You've almost convinced me to have a go... It won't be T2 based, as I
don't have any spare (or socketed) T2s... I may have the odd T4 in the
junk box, though. Any preference on the serial chip I use, or should I
just use a 8250 or something?
I was just looking over Sundance's Serial TRAM and it doesnt even use a
transputer. It just uses C011s to handle the links. Wouldnt that be easier???
There would be no need to get any spare transputers (and they are hard to source
these days). The SMT220 seems to be a very easy design. As John said, it would
be really neat if it can handle modems, etc like a true PC-based serial port...

Pick your favourite serial chip. Link it to the T2
bus, using a PAL for
address decoding and/or to fiddle the R/W .vs. Wr/ and Rd/ signals.
That's about it.
Seriously, it's easy to design with transputers. The bus is designed to
be easy to link things up to. I really think this is a morning's work at
most...
Unfortunately, I have very very little electrical background (almost nothing).
I can but circuits together, but that is just about it :-(
