Hi all, I'm jumping in this thread a bit late, it's a great idea John! I was considering building a Zeta SBC but was missing the S100 compatibility. The board you suggest could be used not only for diagnostic but also to build a compact S100 system based on a 4-slot backplane for example.
a couple of comments : - also agree that serial is essential, video not that much. Propeller is great but, having spent quite some time tweaking the code, there are inherent limitations when running DOS as several programs are addressing the video memory directly and this makes it quite difficult to emulate. as such, we should rather leave the video chip decision to the user and integrate the serial port only. - I own several old school SBCs, as I guess several people here, KIM1, SYM1, TM990 etc and one feature they all have which is neat is a tiny hex keyboard and LED digits. I was wondering if this very limited entry/display device would also be included in the board, probably via a dedicated connector and external daughter board.. that would make debugging, patching, etc quite straightforward, and helping in situations where an external serial terminal cannot be used my 0.002 cents !
