I've been helping the MAME guys simulate a
TS-2624, which is a block mode HP emulating terminal.
I had bought this a while ago, and never dumped the firmware. Unfortunately there is a
large
NiCd battery right in the middle of the board that leaked all over. I've taken some
pictures
which are up under falco on bitsavers.
If anyone has one of these, you want to do battery mitigation ASAP. I'm in the middle
of replacing
every socket on the board since they were all within range of the leakage corrosion.
Also, I suspect the first generation of terminals all have similar hardware with
different
firmware, so if someone has any of the other models (TS-1, etc.) we could get them
simulated
pretty easily once the firmware is dumped.
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?
