This is a CP/M 2.2 computer (pre-IBM). It is working.
It is unique in that it uses the the SIM/RIM instructions and SID/SOD/RST6.5 pins for Serial IO. It uses a 5V USB serial adapter for power and communication to your computer (using a serial terminal program).
There two problems with this approach in that the processing delays between Serial IO means that character can be missed if data is sen...
V2 of my ZTO-80 SBC project, with the end goal of having color graphics(?) along with a BASIC interpreter based off of NASCOM BASIC. A future revision may include support for CP/M.
