Received mine today, XT-USB, working great with my Original Model F, typing now with it. Oh gods I haven't heard that sound and seen characters come on the screen for too long. I have a question about it, though: I have an odd Honeywell keyboard, I made a thread about it when I got it; it's got a DIN-5 and was sold as AT, probably by some doorknob who thinks DIN-5=AT, but it doesn't work work with a DIN-5-PS/2 adapter, the power light lights up and that's it. Is it possible that I will injure my converter by trying to use this keyboard with it, to determine if it is using the XT protocol? I seem to recall years ago possessing a Franklin-branded keyboard that was possibly XT, and that only a few functions worked, one of them being a light. Now of course my Model F doesn't have any lights...
