But, there was a time when I would do almost anything for one. By the way, I found two weird systems at my school. One is the "Writing System" which looks like a PS/2, and we have a bunch of "Eduquest" systems, which are now all in the supply room. >> ps2 models arent really that hard to upgrade. the difficulty only comes when someone attempts to upgrade it way beyond its capabilites. certain 95xx models have used dx4/100 cpu also. eduquest systems are/were one piece mac-like systems designed for school use. proprietary design, but so easy to work on. some even had dos in rom. david
