RCA CDP 18S604B

I have a CDP18S60? CPU board, a CDP18S623A RAM board, and a CDP18S625 EPROM board. I don't have an original backplane to plug them into. They plug into the "Microboard Bus Interface" bus. I have originals of the following catalog and manuals: MPG-180C COSMAC Microprocessor Product Guide MB-601 RCA COSMAC Microboard Computer CDP18S601 MB-623 RCA COSMAC Microboard 8-Kilobyte RAM CDP18S623 MB-625 RCA COSMAC Microboard 8/16/32-Kilobyte ROM/PROM CDP18S625 MB-640 RCA COSMAC Microboard Control and Display Module CDP18S640 MB-601: "The RCA COSMAC Microboard Computer CDP18S601 is a versatile computer system on a single 4.5 x 7.5 inch card. The card contains a CDP1802 CPU, a crystal-controlled clock, read-write memory, parallel I/O ports, a serial communications interface, power-on reset, and expansion interface. Four on-board sockets are provided for read-only memory enabling the user to select 4 or 8 kilobytes of mask-programmable ROM or EPROM, depending on the applications. Because of its CMOS design and low current requirements, the power supply and cooling requirements are minimal. The CDP18S601 Microboard Computer is designed to provide the key hardware for various microcomputer applications allowing the designer to concentrate on the software and special requirements of his specific application. The CDP18S601 is plug-in compatible with the RCA COSMAC Development System II CDP18S005 and the RCA COSMAC CDOS Development System CDP18S007 facilitating prototype design and debugging of both hardware and software." I wonder if any of these docs are scanned anywhere on the net. Here's one webpage which lists the documents but doesn't have links to them: http://bellsouthpwp.net/d/o/dogas/cosmac/dev4.htm -Glen On Tue, Sep 7, 2010 at 9:11 PM, Marvin Johnston <marvin at west.net> wrote:
