IBM 9075 - the PC-RADIO (OT?)

This may be OT, but the computer is a bit unique in its own way (in the fact that there's only two that I've ever heard of/know exist - the one that I have and the one that the person I got it off of still has) It's an IBM 9075 Laptop PC radio. One of the neat things about it is its display. Looking at it, it's reflective (silver), but when it's turned on, it's backlit, and after it boots, the backlight can be turned off under bright light. Anyone have any info on this thing? I just picked on up, and got it to "boot" by connecting a Mac power supply to the battery terminals (7.5v). It came up with the backlight, then did the 640k memory test gave a CMOS battery date error, then booted to drive D, which is a ROM drive. I took it apart, and it has no HD or floppy, an 80186 processor, a modem, and a "Motorola Cellular Packet Radio". First thing: where could I find a power supply for it? The connector is an odd round 4-pin plug. Next: Where can I find IC cards? It has what looks like a PCMCIA slot, but a PC card won't fit, and it is apparently for IC RAM (ROM?) cards. Last: How does the Packet Radio thing work? Where could I find drivers, or an antenna or something for it? Or should I contact Motorola? The computer was apparently used by a Sears Service tech, but that's all I can figure out so far. ThAnX, -- -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1>
