During a familiarization brief at the Atlanta Hamfest, the speaker told of an individual who using a TRS-80 Model 1 for packet communications. I am aware of the limitations of such a setup, but am curious if anyone has developed the software for an IBM-PC compatable to work packet without a separate TNC? I would just like to do it to get my feet wet in packet. If anyone knows of any available software please let me know. Allen R. Shuff AI4G (919) 228-4318

A software solution for the TRS-80 has been written by W4UCH. I took
the basic transmit and receive routines as well as the *great* CRC
generating and checking and transferred it to my Schneider (Amstrad)
CPC464. "It is not easy but not impossible to transfer these routines
to another PC" (W4UCH, quotation may not be 100% correct, I havn't
got the original text with me).
This software solution works rather fine, if you forget that it is
impossible to enter something into the keyboard while you are
receiving or transmitting. The software PLL needs the interrupt to
be switched off, so you can't do anything else...
I intend to make my own keyboard routine, equalized for time delay,
and put it right into the PLL loop (hard work that is?).
To summarize: I know of three PC's a so called software solution
is running on 1) W4UCH's TRS-80, 2) DIGICOM>64 for the C64 and
3) my adopted version of W4UCH for the Amstrad CPC464.
