I have a model railroad controller (Hornby Zero One) which is based around
the TI TMS 100 micro.

I would like to correspond with someone who has had experience with the TMS
1000. It was manufactured in the 1980s.

I am wanting to feed the output from the TMS 1000 into a modern micro and
insert another field.

You won't get much useful info. It's an old p-MOS mask-programmed
4-bit micro (the first really popular one), introduced in the
mid-1970s. You'll have to treat it like a black box- you can't
practically read and you cannot change the program.
