Off Topic about GRiD and 1958 Oscilloscope- Help requested.

I've gotten my hands on a touchscreen GRiDpad. I don't recall the model number, but its just an LCD panel with some buttons along the side, and a stylus. I found a keyboard port pinout for it and build a power adapter, and can get it to ask me to abort, retry, or fail, but I cannot get it to do anything remotely useful. The appeal of this system is that I am a religious GEOS user for MSDOS pc's, and the idea of having touchscreen-GEOS is pretty cool (GEOS has built in support for the GRiD's goofy video resolution, I believe, as well as support for its touchscreen-mouse driver). My question is this: What do I put on a hard drive to get it to boot? It seems reluctant to boot off of a conventional micro-IDE drive that has MS-DOS on it, and if I don't have a drive plugged in it says GRiD Bios v. something.something. When I first got it it had no HD in it at all, just two PCMCIA looking slots, which I would assume to be PCMCIA sockets. One of these sockets is on a daughter board adjacent to a micro-IDE connector. I am stuck. I've had this in my basement for quite some time, but I can't figure out how to get it to boot anything. On a side note, I've also picked up a 1958 Tektronix O-scope (the school I go to was tossing it). It works fine, aside from the fact that the CRT on it scans so far to the left as to be almost off the screen. Does anyone out there have experience with this vintage of oscilloscope? Thanks! Greg
