Aha! Yep, I actually acquired one of those same 8300s years ago; it had that same curly-cord serial cable. I actually have that very ROM in my collection, same label with the same version listed. The 8300 did seem to see a lot of use in industrial applications -- much more than the 8201A. > If I install the rechargeable pack, and plug the wall power into the > battery pack instead of the computer, turn the machine on, and pull the > wall wart out of the wall, the machine keeps running.

What's the condition of the machine itself? For the one I had picked up, the screen and keyboard had seen better days... Gary
