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 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. -- Phil. philpem(a)bigfoot.com http://www.philpem.btinternet.co.uk/
