The Altair 680b in my collection is in excellent condition and is supposed to be working. I haven't had much time to really test it out, but will do so and update these pages in time.

Until then, pictures will have to suffice.

If anyone has one of these that they are about to throw out or do not want anymore please donate it to my collection, I am trying to incorporate earlier computers into my collection.
