I had a Falco TS-1 dating from ca. 1981 in my possession a couple of years ago and dumped the ROMS.
It was based on a Z80 with 6845 CRT controller and 2651 UART.

I have data from two 2732s (Z80 firmware), as well as an EA8316 (2K*8) used for character generation.
That's in text format.

Also have a PDF with some notes on the hardware and reverse-engineered schematic segments.

I didn't have need / get as far as doing an I/O map or memory map for the Z80.

Should I send these files along?
