At issue is where the computer is Tue, 23 Apr 2013 20:44:40 GMT Systems Glitch http://groups.yahoo.com/group/altaircomputerclub/message/3181 http://groups.yahoo.com/group/altaircomputerclub/message/3181 ... Herb Johnson has a copy, his reproduction fees are very reasonable and copies are high-quality.

I looked for the obvious and found a bad connection in a socket. It was a pain to find not having exact schematics, Mon, 22 Apr 2013 01:01:53 GMT corey986 http://groups.yahoo.com/group/altaircomputerclub/message/3178 http://groups.yahoo.com/group/altaircomputerclub/message/3178 I need a copy of the schematics to troubleshoot a ram problem. I think I have some bad ram chips but I also think there may be something else going on.

I appreciate it a lot. A Speech-Aided Modem. That is very interesting considering when it was developed.

It looks too tall- more like the size of the Altair 680's Thu, 11 Apr 2013 04:27:51 GMT Kip Koon http://groups.yahoo.com/group/altaircomputerclub/message/3171 http://groups.yahoo.com/group/altaircomputerclub/message/3171 Martin, That is very good to know. I'll just keep them in that little S-100 case then. It is a very strange machine. I can't detach the front panel off this Thu, 11 Apr 2013 03:55:22 GMT mfeberhard http://groups.yahoo.com/group/altaircomputerclub/message/3170 http://groups.yahoo.com/group/altaircomputerclub/message/3170 What a strange machine!
