Hi,
I've managed to acquire a few Multitech Micro-Professor printers and I'd
like to know just how the heck to use them. I've managed to partially
decipher the schematic, but I can't get the *ing ROM to dump. I've got it
hooked up to a 74HC4040 12-bit binary counter and a Microchip PIC16F874
microcontroller. The hex data the PIC snaffled from the ROM contains some
instructions, but most of it is filled with zeroes. Anyone got a ROM dump
from the "PRT-MPF" or "PRT-MPF-IP" boards? All my boards appear to be
later-version ones, with Fujitsu 2732 EPROMs onboard.
Also, has anyone got scanned copies of the MPF-IP (Micro-Professor
mainboard) user's guide, monitor ROM dump, memory map, schematics, etc? I'd
love to try my hand at writing an MPF emulator, but I don't have an MPF in
my collection.
I'd also like to get hold of one of each of the following:
Synertek SYM-1
Rockwell AIM-65 (with printer)
MOS KIM-1
Ideally, I'd also like the manuals, but if they're AWOL it doesn't matter
too much - I'll just snaffle them from Rich Cini's webpage and print them
off :-)
BTW, the MPF printers seem to be quite plentiful - Greenweld UK appear to
have plenty in stock. I've also got the Technical Reference for the Seiko
Instruments MTP201-20B printer module that Multitech used on the MPF
printer - just in case anyone's interested :-).
There's only one minor thing about them - do NOT, under ANY circumstances,
activate the head for longer than 1.5mS - it WILL burn out.
Just out of interest, what sort of printer mech does the AIM-65 use? I'm not
condoning the destruction of a perfectly good AIM-65 just to find this out,
but I would like to know (in case anyone has a parts list for the AIM).
Thanks again.
