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.

I was talking about the 2624 and yes, they're small 32 byte PROMs for decoding; probably not relevant for an emulator (therefore the smiley) but maybe useful to archive for repair purposes.

On my 2624s two are soldered in and one is socketed.

I can't find my box of TS-1 boards so I'll have to open one up to see what's on there.

I'll have a look for the box with documentation but it might be a while; BTW, my inventory says that I _do_ have a User's manual for the TS-2624 (V1.16).
