Update ! With only the CPU board <no prop i/o> I am able to boot/load the monitor and CP/M using *v1.2* firmware and related files. I'm not familiar with the monitor syntax. Is this a common monitor program ? I'd like to know how to use it.. Otherwise I can load CP/M and get the a> prompt. A "dir" command gives me one file MON-32K.COM.
Also, as mention in another thread, I was having an issue using v2.3 and a memory error. I did the test Josh had recommended to Jeff to test the lower RAM chip with the command R 00 7F. It took a bit but ran and passed. I switched the two memory chips and they all passed. At this point I want to 'assume' my hardware is good, but my setup doesn't like v2.3 yet.
