That picture...
I'm guessing you haven't heard anything from them. Was anyone brave enough to try the phone number [ (818)341-7780 ]?
Argecy have them for slightly less...
TamyaTech list them as, albeit it as "Special Order" if you search for 1387033 in the PN#/Model box, both as refurb and "New Open Box" with manufacturer warranty!
The Argecy page, with its IBM document, shows that this part number was supplied with model 220, which seems to be what is referred to by 3290-2 [ie. type-model 3290-2XX, the second digit specifying the keyboard, the third a mystery to me...]. I have a reference that states "
If I remember right, the model 2 can also use a regular "enhanced" PC keyboard.". The
Corestore picture (from
the "emuterm" page) certainly shows a "Enhanced" type 'board, though it's a 102 terminal 'board (and from the filename it's a Model 1?!...) rather than a 101/102 for a PC/AT.
So, it may well have much in common with other terminal kbds of the time, and be yet another using modified scan code set 3, and so may work with the existing kbdbabel adapter for many Model M terminal keyboards.
This may also be the case for the 122 key P/N 6110344 Model F for the type 5271 "3270 PC" (as owned by Sandy)...
