Vintage Computers -First PDP computers from Digital Equipment Corporation early 1960's

     
 
 Lyle Bickley tell story of how Digital Equipment Corporation (DEC) started to make their first Minicomputers.

How and why Digital Equipment Corporation (DEC) started to make minicomputer in the early 1960's. DEC was already making digital modules for science and industrial use. These consisted of the usual AND , OR , NOR, NAND , NOT gates and various filp-flops. Other special modules were made for instrumentation as well. 

Having all this digital capability DEC engineers wanted to use the modules to make a computer. Management resisted this for fear of competition from big Blue (IBM).  Management finally gave in however the computer could not be called a computer it was called a "Programed Data Processor" or just PDP.  The first was the PDP1 soon followed by the PDP8. Folks began calling them minicomputers.

These early PDP computers  are in great demand by collectors however it is believed only 3 PDP1's still exist and the only one operational is at the Computer History Museum in Mountain View, California.  Later models are available but the very early ones - PDP8, PDP8S are difficult for collectors and computer retro  folks to find. I was very fortunate to have acquired several original PDP8, PDP8S and PDP11/70 computers. My interest is more with historical microcomputers. The PDP minicomputers in the "Bugbook Historical Microcomputer Museum" have now been pasted on to other retro collectors of minicomputers. You will some of my past blog posting about these transfers/collectors.

Thank you Lyle Bickley for allowing me to make this audio story and publishing it on my blog post.  The recording was made while touring the Computer History Museum in Mountain View, California --- lots of background noise however I found the story very interesting and I hope you do as well . Thank you for taking a look - listen.

Vintage Computers- PDP8s & PDP8 Minicomputers have a new home with Bob Rosenbloom

LR Bob & Dave

Bob Rosenbloom came in early this morning by plane from Santa Cruz, California and arrived  at the "Bugbook Historical Microcomputer Museum" warehouse ready to load up by 10:30 AM. Our loading crew arrived about 10 minutes later. Bob's rented truck was loaded with the PDP8S, PDP8 minicomputer and the Systron Donner Analog Computer in about 1 hour - the loading really went smoothly as the Analog computer weighs in at 800 pounds - we used a forklift to get this on the truck. Bob also loaded an ASR33 Teletype for the PDP computers.   The PDP8S was rather small and light weight - it went into the  passenger seat of the truck for a cushy ride to California.
Bob was treated to a Virginia Lunch at our house by my wife Gaynell. Bob and I then did a 2 hour tour of our area that included the "Bugbook Historical Microcomputer Museum" and our "Chantilly Festival Farm" . It was about 3:30 PM however for Bob's California time it was only 12:30 and he took to the road to get a good start on his 2700 mile journey to Sana Cruz, CA.

Update - My wife and I visited Bob Rosenbloom and Lyle Beckley - in October 2013 after they had purchased computers from  our collection - great visit we  also visited the Computer History Museum while in CA.

   Bob arrived today and here is a few words about the journey in his own words, 8-9-13

 The Systron Donner Analog computer weighs 800 pounds - a forklift was need to get this on the truck.

 Easy fellows, this is important cargo.

 On the truck - easy with the right equipment.

WOW it was great to load these computers for a new home and  Bob is sure excited to have them for his collection. Bob really likes the vintage minicomputers and other large antique computer memorabilia.  I like all this also however I am working more with the historical Microcomputers. All of our staff are delighted to see these computers go to a new home where they will be treated very special.

Bob Rosenbloom is heading to Virginia for vintage PDP computers for his Collection

A PDP8, PDP8S and Systron Donner model 80 Analog Computer will be leaving the 'Bugbook Historical Microcomputer Museum' collection for new home this weekend.  Vintage computer collector Bob Rosenbloom is arriving tomorrow on a Red Eye flight.  Bob will be taking these additions to his collection home in a rented truck. This is a long drive to his home in California however Bob feels more confident in personally picking up the computers then trusting a commercial shipper.  I will post more on this adventure for Bob and I as we pack the computers in this rented truck and he is off to California.


Just received email Bob is on the plane and we expect him here in  Floyd VA about 10AM today. 
WOW good timing he arrived today at 10:30AM - see next blog for more.

Bob and some of his collection
