So the main attraction of this board (over say the Z67-IDE+) is that it is 8080-compatible, correct?
Just trying to keep track of all the ongoing projects!

No, all the storage options are 8080-compatible. The H8 bus is
not Z80-specific, so anything that plugs into it should be
compatible with both Z80 and 8080. The original GIDE solution was
a piggy-back on the Z80 chip, so that was not compatible with the
8080 for obvious reasons. But Norberto's Dual GIDE board works
with either processor.

Actually, the Z67-IDE+ and the associated H37/67 board (and PAM-37 ROM) all require Z80. Not a hardware constraint (to my knowledge) but a design decision at Heath…

Right, hardware constraint vs. software/firmware constraint. Like the way I don't provide an 8080 version of CP/M 3 or CP/NET.

Thank you Rick, for your help in the assembly/testing of such board. Nicely done! I’m glad that there were no HW layout issues or logical issues.
I’m very happy to see HDOS working on another controller on the H8 system.
Thank you, thank you!
Norberto

Famous last words. It’s just a matter of a little software… how hard can that be?
