Subject: Battery warning in Falco terminals

Were there 3 PROMs on the TS-1? I don't remember (and unfortunately didn't dump
them, unless you're including the character generator amongst the 3).
They were probably soldered in and I was probably thinking mainly about eraseable chips
and did the CG as well as it (would have been) socketed.
If they were small PROMs, they were perhaps I/O and memory address decoding.
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.
-----------------------------
Don't forget the three PROMs ;-)
There were at least 2 models of the TS-1; the TS-1SP added paging & scrollback among
other features, and there was also the similar TS-100.
Their magnetic core & transformer keyboard technology always intrigued me; very
reliable & spillproof but I never saw it used anywhere else.
