I recently acquired a VAXmate with an LK250
keyboard. The problem is the
keyboard came without the cable. It uses an 8-pin SDL connector and the
usual tiny MMJ-like connector at the keyboard end. I don't know the pinout
and I don't have the necessary crimping tools, is there any source for such
Is it actually MMJ, with the offset pin, like a DEC serial cable? Or is it
just an RJ connector like a telephone handset? And is the SDL end the same
type as on an IBM model M keyboard?
I have a VAXmate buried in storage. With enough prodding I could dig it out
and try to determine the pinout of the cable.
LK201 keyboards use a telephone handset type connector. You might try a handset cord,
though it's possible those don't work because of not having enough copper in them.
At least I remember being told that handset cords have "tinsel wire" in them,
while LK201 cords use real wire.
