Televideo 802 computer?

I've got a Televideo TPC-I, and two of the disks I got with it are labeled "TS-803/803H/TPC-I", which might imply that they are the same machine in different packaging. It's an arm-stretcher, but I have managed to carry it for fairly lengthy distances on a couple of occasions. I could hardly lift a fork to my mouth after bringing it home the first time, though. :) Does anyone know how to program the graphics on that beast? And what was the SuperMouse, and was it actually used for anything? Does anyone know a SAFE way of opening the TPC-I case? It looks like a former owner tried and broke some plastic snaps. I tried unscrewing everything but ended up with a free-floating power supply until I got it jostled back over the screw holes. There must be a special technique to cracking the case?

I have some photos of the TPC-I on my web page. -- Doug Spence ds_spenc(a)alcor.concordia.ca http://alcor.concordia.ca/~ds_spenc/
