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!
