This is a poplar post and I updated it and reposted it. David Larsen
The first 8 bit Intel microprocessor -the 8008 was the result of designing the Computer Terminal Corporation "CTC 2200" logic into a single chip.  The CTC2200 was a successful project to design an electronic version of the 'workhorse' Teletype data terminal  of the 60/70s  - the Teletype was an all mechanical  communications terminal with hundreds of gears and levers. .  CTC contracted  Intel to design a microprocessor however the process was slow and CTC did not  use the design.The result was Intel had its first 8 bit microprocessor (8008).  See short story about the interesting origin of the 8008 at the end of this post.

We are fortunate to have this CTC 2200 in our computer collection and on display in the museum.

CTC's TTL-based desktop personal computer, called the Datapoint 2200, was unveiled in 1970, with cassette tapes for 130KB of mass storage and 8K of internal memory.

The first end user sale was to a chicken farmer in the South who programmed the CTC2200 to write payroll checks. So I you could say a chicken farmer was the first  user of a programmable microcomputer.

The CTC 2200 is densely packed with Small Scale Integrated circuits and other parts. The mechanical design seems to be well done and the unit is solid and sturdy. ( also very heavy )

The design includes about 100 small scale integrated circuits along with discrete components- transistors - resistors -diodes and capacitors. In this photo you can see 4 printed circuit boards under the display and in back of the keyboard.  Their are 4 printed circuit boards under the tape deck area and 4 memory boards next to the CRT display.

The unit was designed to fit in the same area as an IBM Selectric Typewriter. This did not give much room and the unit is packed with cards and circuits.

Here you see the large heat sink on the back of the terminal. It is heavy and weighs about 40 lbs.

Here is some great research about the first microprocessor - Ken Shirriff's Blog 


Short story about the origin of the Intel 8008 microprocessor.

The Teletype was the communications terminal used from the late 50's until in the 80s - first as a data  terminal connected to the telephone system with a modem. It was used to send messages to users and mostly for sending and receiving telegrams. Later the Teletype was used for a minicomputer printer and paper tape punch to store the data.  Long distant voice calling  were so expensive and unreliable it was rarely used  in the 50's and 60s'.

The Teletype was a totally mechanical device that could decode 8 bit data strings - ASCII code - and print all capital letters on paper & also punch paper tape for permanent Storage of the data. The Teletype could also read the paper tape and convert the code into the 8 bit serial ASCII data for transmitting over a telephone line using a modem. The word Byte for 8 bits of data most likely came from this sending and receiving alphabetic characters as 8 bits of data.

ASR 33 Teletype
Teletype 
The Teletype was a great invention however it was a mechanical monster with 100's of cams and levers that could and failed often. It was a mechanical device and very noisy & distracting in and office.

In the end of 1960's, 2 graduates at Case Western Reserve University in Ohio, Harry Pyle and Victor D. Poor, came up with the idea of a high density integrated circuit which would be programmable. Harry and Victors ideas were used to create the logic of the CTC2200 and this became the code for the 8008 microprocessor. When transistors and more importantly integrated circuits became available and all electronic version of the Teletype became possible.

The Computer  Terminal Corporation produced an electronic replacement for the Teletype the "CTC 2200". The CTC 2200 was actually programmable terminal using a custom designed 8 bit computer. The computer was made from discrete components and and small scale integrated  circuits. Microprocessors had not been  designed in the late 60's when the CTC2200 was developed.

The engineers at CTC did have the idea to put the computer logic they had designed into the CTC2200 on a single chip  - making a microprocessor.  A design team went to Intel to have them design and make a microprocessor  using the logic in the CTC2200. Robert Noyce of Intel when approached with this project did not like the idea as he thought a computer on a chip would hurt the memory chip market of Intel by competing with computer makers using the Intel memory chips.  However Robert Noyce did agree to make the chip for $50,000.

The CTC engineers also went to Texas Instruments and ask them to make the same chip to be sure they had a backup source.  The Texas Instrument chip did not function properly and was not used. The Intel chip was a long time in development. The CTC team decided to just build the 2200 terminal with there current design of about 100 small scale integrated circuits and give up the rights to the intellectual property rights for the   Intel microprocessor design --and did not pay the $50,000 to Intel.  Giving up the intellectual rights to the microprocessor is among the worst business decisions ever.

Intel went ahead with the full development of the microprocessor and called it the 8008. The microprocessor used the same digital logic and operational software codes as CTC2200 .

The computer logic in the CTC2200 then was an original 8 bit computer that used the 8008 software code and was  the beginning  of 8 bit computers (8008 microprocessor) for Intel.

Here are some links to more complete stories of the CTC2200 / Intel story. Some of the information I used came from these references.

Their is a lot more to this very interesting story of how the first Intel 8 bit 8008 microprocessor came about - here is the REST of the STORY 

David G Larsen
I  remember for many years I did not think I would find a CTC2200 and wanted to have one for it is one of the first programmable microcomputers. During the late 80's I was able to find not only this fine example and the source also had a  model the CTC1100. The CTC 2200 and 1100 now are part of the "Bugbook Historical Microcomputer Collection"

land for sale by owner - Floyd Virginia

 

Hi friends - most of you know that most of  Post on this site have been about my interest in Historical Microcomputers and Amateur Radio.  

My family has lived and worked in the Floyd County Virginia area for the past 53 years and during 52 years I have been involved in farming and rural real estate.   I just wanted to post information about my life long interest in farm land.  A major part of this interest is the buying and selling land as "For Sale By Owner" for 52 years.

The new "For Sale By Owner"  rack card designed by my associate Jason Gallimore. Take a look at the card information below for a good idea of how my associates and I work with land & farms.

Computer Memory is now 4,000,000,000,000 time larger then 49 years ago

Bugbooks
info click

The Intel 1702A EPROM  (1971) has only 256 bytes of memory - today the USB Flash drive has 1 Terabyte of memory --- that is  an  incredible  4,000,000,000,000 times more memory.  This is a number so large I just can not sort it out in my mind. 

1000 GB or 1 Terabyte
Flash Drive. It would take
125.000,000,000 C2708 chips
to have this much memory!!!!

Moore's law seems to be working after 56 years. Gordon Moore made the observation and prediction in 1965 that the density of components on a silicon chip would double every 2 years. 


The USB Flash drive to the left has 1 Terabyte of memory.
That is 1000 Gigabytes.

It would take 125,000,000,000 of the Intel C-2708 Chips to equal this amount of memory.  A really big change in 56 years of technology.  This 1 Terabyte USB flash drive cost $39.00. 

Please note the Intel C-2708 has 125 times more memory than the Intel 1702 EPROM at the top of page. 








Help wanted 

 A project to make presentation displays for 
 2708 EPROM memory chips and a little history.

Intel C-2708 EPROM
memory chips.
I have 359 of these really nice Intel 2708 EPROM chips purchased in 1987. These chips are all nice white ceramic with gold pins and gold tops. They are part of my 45 years of collecting microcomputer memorabilia. 

What I want to do is make a presentation case/display for use as example of this early microcomputer and memory technology.  

Curious about EPROM memories - take a look here at a my blog post about the very first EPROM -  the Intel 1702A - Get an idea of  how and why they were used. "CLICK"





Intel C2708 EPROM 
A Smart display/presentation case is easily  possible.

A small Raspberry pie microcomputer can be included to provide many photos/videos and text that could be picked up on a smart phone using Bluetooth/WiFi connection. The unit could be connected to the internet with WiFi and linked to selected information on line about the history of microcomputers.

The use of these EPROMs is nice because the quartz window allowing a view of the IC chip. You should know the window was not put there for you to look into the IC - the window allows the memory to be erased by exposing the chip to UV light.

silicon chip that is viewed through
the quartz window on the IC.

It would be very nice to include a way to see into the window on the 2708 and get some idea what the actual silicon chip looks like. This could be a magnifying glass or maybe a photo of the chip would be best. Of course with the smart part of the presentation case just a view of the proper web site may be best way to obtain  more information.





Bottom side of 2708 EPROM

All my IC 2708 chips have a 1977 date code time of manufacture.


More information about EPROM memories - here is my video of the 1702 the very first EPROM chip. You will find this interesting. 






Summary of project:

To build and market a beautiful small  presentation case about microcomputer technology - most  likely out of wood that could be on the desk or appropriate space on the wall. The unit could be just a nice piece on the desk of those who have an interest in microcomputer history or are currently involved in the technology.  It would be a great conversation piece with the smart technology to bone up on the history of microelectronic technology and a real piece of history included - the Intel 2708 EPROM.

Geocaching - Outdoor sport you can do alone.

Geocaching

A Sport you do outdoors.
You can be a team of one.



Chantilly Farm Floyd Virginia  - has a Geo-Cache ready for your hunt. 

This is a sport just made for a time  like this when we can not gather in large crowds and need to keep a social distance.  Our Cache is named "Tilly's Trace" after a wild Bob White Quail who became a friend of our venue and for several years would follow our staff outside like a good buddy.

There are about 500,000 locations in the US - one will be near you - some in exotic places.

There are 11  within 10 miles of Chantilly Farm. This is a sport that may be available  in your neighborhood.

What is Geocaching:
Wikipedia: Geocaching is an outdoor recreational activity, in which participants use a Global Positioning System (GPS) receiver or mobile device and other navigational techniques to hide and seek containers, called "geocaches" or "caches", at specific locations marked by coordinates all over the world.[2]
A typical cache is a small waterproof container containing a logbook and sometimes a pen or pencil. The geocacher signs the log with their established code name and dates it, in order to prove that they found the cache. After signing the log, the cache must be placed back exactly where the person found it.

How to get started:

1. Go to geocaching.com and sign up by loading the official geocaching app.There you will find all you need to get started and be a GeoCache-hunter.

2. You need a GPS to find your Cache.  Most of you will want to use your smart phone.The geocaching app has a GPS app built in and it should do just fine. I tried groundspeak and it seemed to be easy to use. 
3. To find our Geocahe just search cache location Chantilly Farm Floyd Virginia

A brand new Southwest VA geocaching adventure at Chantilly Farm you can embark on! Find the cache located on the farm and write your name in the log book! We hope you have fun and good luck searching! This cache is in the heart of Southwest VA, surrounded by the stunning nature that makes this region so beautiful. Walk down this beautiful bird-watching trail and enjoy the sights and sounds of the outdoors! This trail is the home of Tilly, a beautiful and rare grouse that can be seen and heard while enjoying this short nature walk. This is a fairly easy cache to find with lots of great views, so have fun and enjoy! Note: This cache IS on private property, but geocachers have permission to be present. Have fun and good luck

During our "Ham Radio Mission" to Dominica we visited a very interesting application of using Shipping Containers to make a small commercial building  in the capital Roseau. The design and construction was really excellent. It looked a little out of place along the old buildings on main street. It has a great little coffee shop in one corner. The coffee was good and the price very reasonable.

The  coffee shop is tucked into about 1/3 of a 20 foot container at ground level. The building is constructed from 3 containers.

The interior of the shop is small but well equipped.  The shop also is a wine shop so you have lots of choices.

The menu is in Caribbean $.  About  40 cents in US currency. You can get in town delivery for about 80 cents US.









Small office and retail space building
made from 3 Shipping Containers
in Roseau, Dominica.



You can see here a clever idea - the top container extends over the coffee shop and provides the roof area. A small garden and seating area is built in front of the coffee shop.

The other sections of the are small rental office spaces and a small conference room. It looked like about 6  offices were available and all done very nicely with A/C.  You do not need heat on this beautiful Caribbean Island.

Looking back at the coffee shop where you can see the top container being used as roof for front of the shop.

The railing you see over the container is where a small outdoor seating area was made with a roof overhead to be used by the tenants and their guests.

The whole country of Dominica is small 15x30 miles in size with a population of about 65,000.  The capital Roseau has 15,000 people.

Look carefully and you will see a typical Dominica tiny house just over the roof of the while auto. The streets are very narrow and with autos parked on both sides there is barely room for one car to drive down the street. Look closely and you will see the ocean at the end of the street.

The island is still recovering from hurricane Maria in 2017.

We have visited the island 32 times in the past 23 years.  Our purpose has been to help with Disaster preparedness communications.

The island is a mix of old and new buildings. The island historically over the past 300 or so years was dominated back and forth by the French and  British.  Most recently it was a a British Colony and the dominate language is English.

In this photo you can see some of the cobblestone sidewalk that has been in place for hundreds of years.






Port Roseau in Dominica.
Dominica is the nature island of the Caribbean and has many beautiful water falls, hiking trails, hot sulfur spring bath pools & great Caribbean food - my favorite food!

You can see in the photo a cruse ship in port at Roseau. The ships  make a 9 hour day stop, however, they are an important source of income for the island folks.

Amateur Radio SOTA - Frontier-women YO6EVA conquers Summits

Amateur Radio YL Acitivties 
YO6EVA - Eva Kelemen Gajdo 
YL SOTA operations

Summits On The Air
Heather Holland ZS6YE sent me a very interesting a copy of the "yl.beam #81 April 2020" a few days ago.It had a very fascinating  story about a  YL doing SOTA "Summits on the Air" activity.  It was interesting to me because I have had an  interest in SOTA and my wife is an active YL ham  - Gaynell Larsen KK4WWW. This is just a part of the full newletter - Thank you Heather ZS6YE

I think you will agree with me the Story of YO6EVA and her SOTA work is facinating.  DAVID KK4WW - ENJOY THE READ 
If you are not familiar with "Summits on the Air" SOTO you may find a new part of the ham hobby you will want join.







-------------------------------------------------------------------------------------------------------

SEE VIDEO OF THIS OPERATION 
Frontier-women conquers Summits
Women usually go to the hairdresser, go shopping, and usually do "feminine" things when they have time off. Éva Gajdó, a teacher of computer science at Tivadar Puskás Vocational High School, who teaches programming on CNC (computer-controlled) machines, does not like this. She climbs mountains. And up there on the summit, she transmits radio signals. It may seem a strange combination  at first, but it is recognised as a sport.  Established for less than a decade and a half, it is already gaining in popularity and Éva Gajdó has accomplished something very big in this sport in a short time. Her success is the envy of her fellow men, which as she is a Szekler, does not often happen. (The Székelys derive their name from a Hungarian expression meaning "frontier guards".)


 Éva Gajdó has been roaming the mountains since she was a child. She became a true lover of climbing when one of her teachers took her on an expedition. Then life sank into the ordinary course of events: she got married, the children came and there was little opportunity to conquer the peaks.
 Several years ago however, talking about childhood dreams with a group of friends, Eve recalled that when she was sixteen, she was determined to climb Mont Blanc. But it seemed it would  remain just a dream.  Then, a few days later, a friend told her that the Szeklers were hiring amateur climbers and heading to Mont Blanc.
"I didn't think, I called Tulit Sombor, and  applied," says Eve.
Two months of tough training was unsurpringingly not enough to qualify for the team. She also found her gear was unsuitable. She  hiked in velvet pants and her ancient boots caused problems; the two months were agonizing. But Sombor reassured her that she  had all the skills and with a little training, could climb Mont Blanc.  It became a passion and she has not missed a weekend in five years and  even celebrated New Year's Eve on top of a mountain.
She  applied for another expedition, but unfortunately before her departure she sprained an ankle. She was able to climb this year, but couldn't use the  radio.
In order to understand why Eve should have been broadcasting radio signals from the highest peak in the Alps and what activation means we need to introduce the sport called SOTA.
The acronym comes from 'Summits on the Air', this radio competition was launched in 2002 by radio amateurs who combined there passion with mountaineering.
The competition consists of climbing the designated peaks - at least 150 meters above its surroundings - by hiking, and from the 'summit' the hiker must establish at least four radio links with other radio amateurs around the world (meaning activation).
The peaks  score between 1 and 10 according to their height and can be activated once per year. The map provided by NASA to radio-operators in Romania has about two hundred SOTA peaks, of which 250-300 can be climbed under normal conditions, ie on a more or less well-marked path. A walkie-talkie can achieve the necessary score if it is successfully activated, that is, it has been climbed and  a minimum of four mandatory contacts made. After earning a thousand points, the title 'Mountain Goat'  and trophy will be awarded to the competitor. Achieving a thousand points usually takes several years to complete. Eva did a special job here too.
Eve met a man in Jezer (Bosnia and Herzegovina)  on a hike,  while trying to establish a radio connection at the summit. He was interested in the subject, because there is a radio club at Puskás Tivadar Vocational School, Budapest, and he was wondering how to create something new and interesting for the students.  At that time, he had no plans to start radioing himself, or that hiking would become a competitive climb. He asked a teacher at Transilvania University in Brasov, Csaba-Zoltán Kertész, if he  would come and  introduce SOTA to the children.
Since January last year, Csaba has gone to St. George every Tuesday, trying to infect students with the radio virus. Because amateur-radio amateur is well-suited to the younger generation, SOTA is becoming more and more popular, including foxhunting, but knowing the basics of radio is essential.
Eve had no childhood dream of becoming a radio amateur but her dedication to teaching led her there. Csaba Kertész enthusiastic for  the Tuesday afternoon classes included taking the students on several trips, where they could experience "live" what  walking radio was about.
 Eva thought that if Csaba couldn't come for some reason, it would be a good idea if someone could take care of the children. But to do that she needed a radio license.
- You have to take a very tough exam: electronics, knowledge of frequencies, first aid. You have to learn the phonetic alphabet that is used in radio,  to know what phrases can be heard and what are not, so there are ethical rules as well. She passed and received her radio callsign: YO6EVA.
(YO = Romania ID, 6 represents the area, and EVA unique, individual)
I'll do it in a year
- As I had passed my exam, I went with Csaba to a SOTA marathon. It was staged in the Bihari Mountains, Romania, and was worth exactly one thousand (1000) points for someone who had done it for six or seven years. I told Csaba, as I go to the mountains, I could earn a thousand points in a year.
In the beginning it was really hard because I didn't know anything about radio, I didn't have any equipment, I borrowed a walkie-talkie, which had only 300 meters range I went up the mountain and couldn't activate it.  I persuaded Csaba to come with me to collect points,  but the points accumulated very slowly. Finally, I bought a serious radio, and then the "party" started.
- Has a thousand points been reached in one year?
- Not easily, but it was.  I went to Nagykő (Transylvania, Romania) alone and for the first time spoke on the radio and I was so scared I switched it off. There was bad weather at Nagyhagymás, I went up four times, but never activated it; in minus ten (-10) degrees activating radio was not a lot of fun. Disappointed I told Csaba it wouldn't work for me, but with the support of friends, somehow I hung on and continued. The biggest challenge was to get to the summits that I would not have gone to otherwise, I had to cut through a sign or path like in the jungle. Finally a thousand points were reached, 131 different peaks in a year.
- 131 peaks in a year, one average every three days.
- Most were the four eight-point peaks in a single day, 40 kilometers of walking at 3500 meters.
What's next?
With her unique performance, Eve has earned the envy of many of  the male walkie-talkie operators,  She reached a thousand points in May - since then, the number of activations in Romania has increased, with another SOTA marathon being organized by December 1,  interest in the sport has revived..
Although Eve has achieved what she set herself to do, she does not intend to stop walking but not as intense as before. Also  because all of the closest peaks have been  activated and  new ones are usually a two-day hike away - She would like to climb the highest peaks in Europe, but she would need to take another license before she could broadcast abroad.
Eve talks enthusiastically about everything, but when it comes to the mountains, her eyes shine the most.  What does mountain climbing, mean to her?
- Its an  obsession with me, an addiction. The mountain has given me so much, I try to pass that on to the students. Everything revolves around the mountain, I don't go to the beautician or to the shops, and my daughter says you have seven pairs of hiking pants, but you just don't have anything to go to school. SOTA has exposed a whole new side of climbing and fox hunting.

The YO SOTA Marathon is a mountain hiking and amateur radio event that takes place every year in the beautiful Carpathian mountains of Romania, being supported by the “Romania’s Radioclub” Association (ARR). The purpose is to operate radio equipment from mountain tops in the Summits On The Air award scheme, and is open to anyone interested in amateur radio. It lasts about a week (during August) and presents the chance to gather a large number of points in the award scheme.

 1st  YL Mountain Goat in Romania.
YO6EVA Eva Kelemen Gajdo reached a thousand points in May 2018 becoming the first YL Mountain Goat in Romania. An admirable achievement, showing great dedication and a nice example to follow. What is truly amazing, that she achieved this goal in just under a year after obtaining her HAM license, learning all about  what it takes to operate a radio while hiking  around the summits of Romania, whatever the conditions or difficulties.  Hail, the rain, bad propagation could not deter her in achieving her target.

Romanian yl  Éva YO6EVA active on Argentina Mountain
yl from Romania - YO6EVA Éva Gajdo and Csaba YO6PIB with colleagues from Sota Mendoza, Argentina, activated SOTA (LUM/PC-004) Jan. 2020
Éva Gajdó  YO6EVA and  Csaba-Zoltán Kertész YO6PIB  came to climb and activate Aconcagua during the first two weeks of January 2020.  Aconcagua (LUM/PH-001) is the highest summit in the SOTA programme, altitude.6960m.  However they could not reach the summit due to very high winds. They began  their descent as per schedule feeling very disappointed, especially regarding the Mendoza radioclub friends who had supported the expedition, prepared to 'chase' (on air) and even to make 'summit-to-summit' contacts. They made 2 attemps and spent 3 nights at over 6000m.
On their arrival back in Mendoza,  Eva and Csabone had one day left before catching their plane home to Romania. Tthe  Argentina SOTA group was also disappointed and it was decided to activate another summit where they could communicate in VHF and HF as originally planned.
 The route was chosen so that  Eva and Csaba could enjoy seeing animals from the local Villavicencio reserve, mostly guanacos.Tthe group was also lucky enough to see several condors flying over the activated peak in the Paramillos area.
The group were surprised by the number of active  stations that made contact. Many operators were keen to communicate their enthusiasm at contacting the visitors and to wish them a safe journey back to Romania. Unfortunately propagation conditions for HF were not good, although some contacts were achieved.
The Argentinas were happy that Eva and Csaba had managed to activate an Argentine summit and although it was not Aconcagua, that they had enjoyed the local hositality of Mendoza.
