BERNARD,
I too am still active in PACKET however I use a Commodore 128 for
all my uses. One for internet use and another setup for Packet
on VHF only. I use GERMAN software called DIGICOM V5 which uses
the worldwide compatible software. I built my own TNC strictly
for PACKET/VHF. In Hawaii we have a statewide packet digiptr
setup, with the digi on top of Mt Haleakala. I can easily reach
that. I think its APRS which has a lot of addnl cmds I am not
familiar with. As to TNC'S that will work with PC's and or
COMMODORE computers the following commercial TNC's are all suitable.
MFJ (makes several versions)
Packrat PK232's with latest upgrade ROMS also (useable with
Commodores if adapter is also included.
KAM+ Kantronics also with latest ROMS is MBX and fully compatible.
Hope this helps. I was handling all MARS traffic via Packet between
Ft Huachuca Az and Schofield Barracks in Honolulu for many years till
I finally resigned last year. After 70 years with pre WW2 then
MARS till last year I decided I better rest and take it easy.
