Dragged one of my full size Model M out for a go this weekend. First full sized keyboard I've used for a while.
Big and noisy
I'm jealous. I want one. Gonna make pics when I have one mmmm. I will annoy everybody around me SO MUCH.
I have two. One has an SDL cable, the other a fixed PS/2 cable (which I had to rebuild as someone in the keyboard's past has thoughtfully snipped the cable off just where it entered the case.
If you're in the right place at the right time you can pick u pa bargain on these.
A little cleaning, a little soldering, sacrifice one old PC/2 rubber dome keyboard, and hey presto!
