Looks like the CLI PHP error on SDF is fixed, yeah! I need to catch up my grex and sdf phlogs... I attempted another build of the z80 CP/M machine by Grant Searle and it still doesn't work, while I was able to get the non-CP/M version working fine. I am wondering if there is something wrong with my SIO/2 chip, or some other component... At this point though, I'm planning on building the 6502 SBC, and then thinking about trying to get an rc2014 system started. I also ordered some prototyping boards and IC sockets, so I can build a more permanent version of either the simple z80, or the 6502 system, whichever one is more fun in the end. Still, I would love something that is a little less dependent on an external system as these SBCs are. Something with some way to store and retrieve basic programs... even if it's on cassette.
