Subject: Battery warning in Falco terminals
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'm confused; I've got at least one TS-2624 board which is identical to yours and
also several TS-1s and TS-1SPs, but they all had the backup battery in the power supply
so, although the power supplies were damaged, the Main boards were not (although it's
amazing how far the corrosion can migrate).
The TS-1s and TS2624s were very similar but certainly not the same board.
I've also got some of the newer Fame style models; guess I should look at those but if
they have the pox then it's probably too late.
FWIW, I've also got a bit of documentation for these and various other Falco terminals
(User, programming & service) but alas, not for the 2624; I can also certainly dump
any firmware that I have.
