Hi Stephen,
A good challenge, indeed.. Not 100% certain I'm up for it but I'll
give it a look! Send me those mods if you would. Probably the best
approach would be to make the same optimization to the display code
that you did for the M100.
My prior attempts at clearing 200 bytes in the
I agree, it’s fabulously mind-boggling. The recent activity alone on this list
has been inspiring.

Can I just take a moment to express appreciation for being in a community where
170 bytes is a "BIG HOLE?" Because I love that.

Wow. Good show Steve! OK, Gary - Let's see your stuff... "8)

I can share the mods I made to the M100 ROM. You might have a hard time to
get a working ROM for NEC.
The reason why is that, on the M100 ROM, I have a patch that creates a BIG
HOLE. I found an optimization
Great news!
Question for you: I know the dual-CPU board doesn't physically fit
into the socket space in the NEC machines, but would your single
NSC800 adapter fit just fine?

One thing that would be nice, is a new version of tsdos that avoids all
the special 80c85 opcodescompatible with 8080. Then it could run on

Update.
I have refined my NSC800 aka Z80 conversion for M100 somewhat.
I now have a very simple adapter board that converts the 80c85 socket to
accept NSC800. Small and simple. Plug and play.
The main rom needs to change to a patched version that I have. To do so,
you need to use one of the
