I'm looking for any documentation that might be around for APC Automation Products Company Microprocessor, PCB ASSY 0002-3768-151 which is a Motorola EXORBUS CPU board with the following goodies on it, 6808 CPU (w/ 4.000 MHz xtal) (2) 6821 PIA (4) 2716 EPROM M58725 2Kx8 SRAM 6840 timer 6850 ACIA there's a bipolar PROM too which is probably used as an address decoder of some sort. These appear to have been offered as an OEM product for integration into customer's designs rather than being some custom board for a specific purpose. Most parts are dated '83, '84. I have several of them. Any info about jumpers, address decoding or certainly schematics would be greatly appreciated! Chris -- Chris Elmquist
