    I'm borrowing a PK-80 to try packet (I know, I know). I can't seem to find a manual anywhere online. I've got a cable that needs pin-outs but no idea what goes where.

    FWIW, I'll probably borrow a PK-232 soon. But I'll need a manual for that one too, if you can point me to a pdf online.

    The AEA PK-80 modem was released in late 1986 / early 1987 (as I remember).
    http://www.geocities.jp/tnc_gallery/pk80-e.htm

    The PK-80 was AEA's clone of the TAPR TNC-2.
    Still good for 1200 bps packet and is upgradable with add-on modems for 9600.

    Virtually identical to TNC-200(Paccomm), MFJ-1270(MFJ) and TNC-2A(GLB).
    Suggest upgrading the firmware with latest TNC-2 or PacComm Tiny-2 firmware.

    It should be the same as the PK-88 I have 2 and 2 manuals.
    Just go and buy a serial cable from your local computer store and plug it in. You will also need a serial card in the PC and a terminal program.

    The PK-88 TNC can also be directly connected to a Wyse - 50 terminal via the serial cable. I would think the PK-80 is connected the same way.

    Also use the same cable with the PK-232 TNC.

    I borrowed a PK-232 the other day. Hopefully this one will have better capability and ease of setup.

    I do not recall it needing a null modem cable, I thought it was a straight serial cable. A null modem cable would have him cursing up a storm, and there's no real identifiable marking to tell the difference (this is the voice of experience speaking ;) ).

    That could very well be, the same as the picture a DB25 Male to DB9 Female serial cable. It has been a long time, I still have my original cable hooked up to the TNC. It all still worked a year ago on my old Win-95 box, but no one on packet to talk to.

    I'm looking at the box now... it was set up to have Radio 1 on some sort of special pin connector to a mic jack and a tiny headphone jack thing. Not sure but I'd guess it was originally set up on a pre-706 ICOM with the round pin connector in the front.

    Seems I could potentially order the special cable from MFJ (*gasp*), but not sure if it needs the roundish accessory looking plug one, etc. I would likely use it on a 7100 since it has VHF/UHF/HF capabilities.

    I sold my PK-80 manual and PK80 Modem on Ebay about 1 year ago, had it since the 1970's.

    What I do when looking for something that rare, I do a search on Ebay and then when its not found, you can save the search and you will be notified via email or phone when it appears, if ever.

    It works great. Scored an old and rare ICOM 215 FM rig that way.
