I really dont have any preference to a serial chip other than that it should be
reliable and easy to source. I have no spare T2s either. All the spares I have
are the T400 (2-link) transputers.

transputer schematics (especially trams). Ooops, I should take that back, there is
the DTC (DSP + Transputer card) card that comes with schematics and is free.
