It's the old 26 pin laptop/portable/keyboard standard to 34pin.
It's basically this: http://www.martinruss.com/sy99adapter.html
Some wires are straight through, some are twisted, some are shifted, and it needs a mini-power plug to come out of the 26pin end too.
Except for Pin 7, that can't be connected, its +5V on mine (not GND). There was/is a guy who made them as a single cable, but they're only available now with a floppy drive for $70. I can't be guaranteed it'll work either, it just looks 95% likely according to other sources.
I was crossing my fingers someone had a dead Toshiba lying around.
If my bonus comes through I may just order one from the US, prices are silly though :S
