The very first personal computers - How many are left?

I doubt it, I have seen many Altairs and I think the highest serial number was around three thousand something (8800 and 8800A's),lets say 6K were made, I find it hard to believe that MITs made another 44,000 B's and BT's by mid 1978 when the line was discontinued. BT's were introduced in, what, late 77 after MITS was sold to Pertec. The line was discontinued in less then a year because of lack of sales (many better options were available at this time). So I must assume not many BT's were sold, but I have no serial number data to confirm this. I have only seen 5 or so and most serial numbers were in the hundreds, I think I saw one in the thousands. I would guess not more then 10K were ever made (all Altairs including the 680,Attache and Sherwood). If you (or anyone for that matter) has serial number data that disagrees with this conclusion please feel free to correct me! steve ------------------------------------------------------------------------------
