Did you notice the labels on the power switch? It may be my immagination, but it looks like it's OFF up, ON down (at least the upper label seems to be longer...

I would suggest, if you can find it, pick up a copy of Stephen Levy's book "Hackers - Heros of the computer revolution". This is a terrific book that covers...
Another right time/right place thing that made the Altair the first *commercially viable* computer was Altair BASIC. Bill and Paul developed this high level...

John- You said you have an 88-SIO-B cassette interface. I assume you mean you have the piggyback 2-board set (SIOB + modem board) known as the ACR Audio...
Any thougts out there? I bought a half populated tanner 64k static ram board. It uses 2016 ram chips. I am trying to get it to work in an altair with a Basic...

I wrote to the seller again and this time I got an answer. He *thinks* it has a 16-slot single large motherboard. If that's the case, it's most likely an...

Profpresbury, Unfortunately, your missing front panel label is not a simple decal. It's a strip of sticky-backed painted aluminum. There are a lot of 8800's...
