I have a friend whose organization recently bought 95 Radio Shack Model 100 portable computers. They all have 24K RAM, and my friend wants to upgrade them to 32K. There is a small panel on the bottom of the machine which upon removal reveals two IC sockets. One socket is a standard 40 pin DIP socket, and the other is an easy-insertion-type 28 pin DIP socket. I would like to think that the 28 pin socket is the one used for RAM expansion and that plugging in an 8K CMOS static RAM (6264?) would do the trick. It's probably not that easy. Does anyone have one of these beasties? Does anyone have information (or pointers to information) on the internals of this computer? Radio Shack wants $119 for the 8K expansion plus $15 to install it. Is there a better (cheaper) route? Any info on the subject would be greatly appreciated.

Doug,
the 40 pin socket is the access to the Model 100 System Bus.
The 28 pin socket is used for an optional ROM. Sorry..
A service manual is available for the Maodel 100 From Radio Shack. Ask for
26-3801/3802 Service Manual. Additional RAM is easy to install. See ads
