The computer has been sold - thank you to all that inquired about this Altair.

MITS ALTAIR 8800 computer for  Sale. This computer has been restored to working order by Win Heagy. Win has been a vintage computer collector for years and has restored many old computers including an original Digital Equipment PDP-8 minicomputer (PDP-8 work is still in progress). The ALTAIR 8800 is in nice condition and displays very nicely. I have posted many photo's below to show various aspects of the computer and the documentation that comes with the 8800. It is nice to have this computer operational and ready for a new home after resting in our museum warehouse for more then 25 years.

The computer serial number is 220414K and I believe the numbering started at 220000 --- that would make this number 414 in order of production. The K at the end of the serial number indicates that the computer was sold as a kit and it was up to the purchaser to assemble and test the product. The low serial number would put the computer in the first month or two of production by Ed Roberts "MITS" company --- a nice early ALTAIR 8800 computer.

Contact me here for purchase or more information.

An ALTAIR 8800 sold today on Ebay for $9001 and a few weeks ago one sold for about $10,000. If mine does not sell soon I will remove it for sale and put it on Ebay. 4-12-15 - Checking the Ebay sale -- it did not make the reserve price so hi bid was $9001 but no sale.

Here are some comments about the ALTAIR 8800 computer by Win Heagy.

1. Runs warm with the cover on.  If you plan to use it for extended
periods of time, consider installing a fan.
2. Some small dings and marks on the exterior, as is to be expected in
a 35+ year old machine.
3. In order to modify the original hardware as little as possible, an
extension cable was made for the original 2SIO serial cable.  A large
piece of white heat shrink tubing covers the DB25 connectors of this
extension cable and the original cable.  This extension can be removed
or reworked as desired.
4. The 4K RAM card was used for loading 4K BASIC in the video.
5. The MITS 1K Static RAM card was not extensively tested.  The RAM
test routine I have did not seem to work properly on this card.
However, as is seen in the video, I toggled in the “Kill the Bit”
program from the front panel using this card as the RAM card and it
works.  The RAM chips are soldered on this board.
6. Most of the documentation included with the system is not original.
Most of the manuals and other documentation is available online.
7. The 2SIO card is picky.  Be sure to use a good quality USB->Serial
adapter - or a real serial port on a PC.  The 2SIO expects serial
level voltages and some adapters cheat a little.  I had four different
adapters and only one worked.
8. A second serial cable/connector is included for the second port on
the 2SIO card.  This cable and port was not tested.

I am selling this and other duplicate computers from the collection to help pay the rent in the commercial rented space used by our museum. We try to have the museum open regular hours and have paid help as assistant curators in the museum. We live in a very rural area of the Blue Ridge mountains and not many retro computer folks to volunteer in the museum. Our little town of Floyd, Virginia only has a population of about 400. The county population is small and we are in a beautiful place with 42 miles of the Blue Ridge Parkway as our Eastern boundary. The county is agriculture based and is known for it wonderful mountain music and many very creative artisans.
