I have most of one. It has been quite some time since I worked on it,
but I had it running a modified version of the M100 ROM.
It was working on an Actel FPGA at the time sometime in the 2009 - 2010
timeframe, but I believe that FPGA is now obsolete. But it is mostly
just Verilog / VHDL code that could be ported to any FPGA.
When I say modified ROM, the modifications were because I had extended
the 8085 CPU with 24- bit registers and relative branches. I had it
running in simulation a few months back. From what I recall, I had
modules for the LCD, keyboard, 80155, etc.
What type of FPGA are you interested in using? I typically use Xilinx
these days.

Not sure if anyone here has an FPGA programming knowledge and who could make a
core or know someone who could make a core for the 100/102 for the MiSTer
project. Would be a really awesome option to have an FPGA version of the 100.
