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.
