Hello!
Have you seen network card for Timex?
I just got upgraded Timex Computer 2048.
It has extra board with 8251 interface and some
very interesting ROM changes.

Some time ago was topic concerning Timex modem and
using the 8251 of it as serial interface. Here you
have almost ready solution. :) It traps tape transfers
and provides extra functionality.
I'm looking for someone experienced in Sinclair BASIC
source to analyse and describe the ROM changes and
network protocol used.
Best regards.
