I wasn't aware of the utility board that Andrew mentioned, it might be a good solution.
Something as simple as adding a small amount of ram/eprom and a single serial port to a Z80 board would give folks an entry point. As long as the ram could be disabled later it wouldn't take up much space or cost. Using a FTDI/USB cable would even eliminate the need for RS232 and the associated jumpers, drivers etc. Sadly I lack the expertise to put it all together. - Gary On Friday, May 9, 2014 1:08:29 PM UTC-4, monahanz wrote: > > This “All in One” S-100 board request/issue comes up from time to time. > With current static RAM chips and high density I/O chips it might be > possible to put together a reasonable Z80 board “All in one” S100 board for > a specific hardware setup.
