The simplest implementation of 80c85 is MiniMax 8085 by Sergey Kiselev.
It has a very small amount of chips and is easy to build. It has also extension port for connecting keyboard and display.
But for ROM exist only TinyBasic and mon85
I really wish I could figure out FPGAs! I’d love to run this and make some
hybrid M100/internet thing. Have an app that would be like the TRS-80 Prodigy
or something. PCB layouts and FPGAs are way out of my wheelhouse at the moment.
Awesome work!

Ken,
That is awesome! I am admittedly a mechanical engineer and I took one
semester of computer engineering and VHDL programming and changed majors (I
was more of a beer drinker than D&D guy). In any event I will rope in some
colleagues and badger them with questions. Another question is whether

In need of a flat ribbon cable for the Tandy 102.
Any recommendations for source?
Hey Rob,
Actually, the time did finally advance. I forgot that this is a
simulation, so it takes quite a bit of real-time for even one second to
pass in the simulated design. It is up to 5 seconds now in my
simulation after about 5-6 minutes of real time.

Hey Rob,
I have an RTL design I worked on YEARS ago where I was trying to get the
Model 100 in an FPGA along with some extensions. It was back when there
was a lot of talk on the list about a Model 401. For those who weren't
around then or don't recall, the Model 401 was something that was
I have followed this email list for a years and I have never asked a
question...but here goes! I am sitting here with my model 100 and I had an
idea to 3D print a replica case and get my hands on an LCD and mechanical
keyboard and try to faithfully reproduce the Model 100 with simple
additions. I h
