I have the hardware manual for the HX20, which includes schematics, etc. I should therefore be fairly easy to work out the memory map of the main processor (assuming it's not already in the manual). Problem is, there are 2 processors in there. One runs the user programs and does some I/O, the other does timing-criitcal I/O. And there's no information on the second processor in the manual. Well, OK, we know what it is, and how it's wired up, but this one runs from interal ROM, and there's no info on the ROM code or the protocol to talk to it . It communcates with the main processor via a serial link, which can also be switched so the main processor talks to the Serial (5 pin) socket on the back -- the one used for the TF20 disk, etc. There is supposed to be a software reference manual as well, but I don't have it ;-( -tony

Alas I have no scanner (nor any way to display the output of one), so I don't think I can help with this :-(

Does anyone in the S.F. Bay area need or want a UMAX 600DPI/30bit color/flat bed/SCSI interface scanner? Comes with scanner, software (PC

3.1/Win 95/Win NT), cables, terminator, and SCSI card (ISA). This was my scanner of choice until I upgraded to a USB based scanner. I can make

good deal ($10 and its all yours, bwa-hahaha) or come by Saturday to our garage sale and bargain us down :-)
