run very well as Z280 offers larger memory, I&D space,? supervisor/use,
and MMU so a real protected

That's got me thinking... Suppose I redesign the P112 board to take a
Z280 CPU.? Would you guys go for it?? I'd like to come up with a way
to use a socketed CPU or put a surface-mounted chip on a carrier board
to allow greater versatility with playing with different Zilog chips.
Hello David
I saw your posting on the cctalk mailing list regarding RSX180.
It is Hector Peraza that's been tinkering with this.? He intends
making the
full source-code available via SourceForge or GitHub but is still
working
on preliminary web pages and documenting etc.? No doubt he will
provide you
with more details.
I've been tinkering with a Z280 system designed by Bill Shen (the
Z280RC on
the RetroBrew web site at
https://www.retrobrewcomputers.org/doku.php?id=builderpages:plasmo:z280rc
)
and have contacted Hector about porting it to the Z280.
That is the easy part, where is the 99 cent dumb terminal to go with it?
Ben.
