I have recently acquired a QuickPAD Pro "keyboard":

http://www.quickpad.com/Item.asp?id=5&c=2

The machine is in reality a little 80x86 DOS computer. The only obvious pitfall is the black and white only alpha-numeric display. "The LCD screen is 480 X 128, which is a subset of CGA. The controller in the cpu chip (Vadem VG330) has a built in controller capable of CGA or VGA modes, but it is not 100% compatible with the “PC”. All screen output should go through the system BIOS, which is detailed further on. The screen is always in mode 6 (CGA)."

Here is a link to some very crude developer's info like that above:

The Quickpad has a CF slot in which I am contemplating inserting a CF card containing the DOS flat download.

I have a couple 128M flash cards on order from eBay (this is an old machine, that's all it can handle).

I am a total newbie. The last serious code I wrote was in machine language when computers were still ttl. Am I headed for a train wreck, or might this work?

Sounds like a fun device to play with. I don't see a train wreck here, I see lots of opportunity.

The most important thing is kept secret: the CPU. If is is not compatible to at least 80386, then FASM won't run. However you will be able to use FASM to cross-develop for it, since FASM can brew 8086 code (if you take care, no "only 8086" directive), and it seems to be "sort-of" 8086 compatible.
