    Default IBM InfoWindow 3477 (P/N 69X8052)

    Hey All,

    I found an IBM InfoWindow 3477 (P/N 69X8052) in my area for what I think is a pretty decent price ($40 local pickup). Before I jump into the purchase, I'm trying to figure out the following...

    1) Can this terminal be fed via serial (either directly or via transceiver of some type)?
    2) Since it does not come with a keyboard, are there any keyboard options or am I limited to buying the IBM 1395660 122-key beast?

    Thanks!

    Ah, ok. Thanks!

    I assume then there is a transceiver involved to get it connected to the twinax bus?

    It's actually a self-terminating cable

    though most installations migrated from twinax to twisted pair and RJ panels connected with twinax to tp baluns

    Right, but I must be missing something. I don't see a twinax connector on the thing. How would you connect it?

    Here is a picture of the back:

    there is a different style 'T' cable with a 15pin instead of a twinax connector
