    Default IBM Extender Card

    I purchased a 5161 in mint condition with sender/receiver cards, and have a 62 pin cable coming from the US right now.
    But unfortunately one of the cards turned out to be a serial board! So I'm kind of stuck.

    Does anyone have an Extender card laying about to save my hopes and dreams?

    PayPal payment, and I have a freight forwarder in the US and UK.

    I am in the same boat, it's frustrating having the unit and not being able to use it, if I come up with a solution, then I'll let you know.

    It's sad, have to start scouring eBay for PC's and XT's looking to find systems that just might have a card in it. A few years ago I looked at the possibility of modernizing what it would take to connect an expansion unit but it never gained enough traction.

    Yeah I'd be keen to know if you find a solution lutiana.
    Ideally I'd like it to respond/look/behave as if it was genuine.

    This 5161 (except for a little bit of paint damage on top) is pristine and still bright white. So I'm eager to get it operational,

    Why can't replica cards be made? The schematics are documented.

    I can't see why not, but I certainly don't have the skills to do so.

    I thought it was the availability of certain components or lack there of was the problem and no one wanted to design a PGC (is that the right term?) for it.

    As I understand it, the only hard to get component would be the 62 pin connector, the rest is all standard and easily available logic chips.

    I think there would be enough people with XT's and PC's to warrant one being made. Cost prohibitive, but beggers cant be choosers.

    $US5 from our friends in China. Pretty sure that's a match?

    Edit: nevermind, that's for cables, but I did find this for PCB mounting: https://www.aliexpress.com/item/10pc...ceBeautifyAB=0
