    After many years since last using AX25 Packet I have decided to dig out my old Proccomm Tiny2 Mk2 TNC only to find I require an Eprom for it (27c256). Can anyone tell me where I can get an Eprom or the binary code so I can start playing again.
    Thank you

    Gwyn Reedy, W1BEL (SK, 2006) founded Paccomm in 1985. He passed away 14 years ago.
    While Gwyn’s wife ran the company for a few years, the web site is gone.
    ==
    The Tiny-2 Mk2 TNC was based on the earlier TAPR TNC2 design.
    Firmware EPROM for this model do appear on eBay.

    I am working from home at the moment (aren't we all?) but I think there are some 256 eproms sitting around at work. If you still need any then give me a shout and I will try and find them for you.
