I've always believed that the keyboard from a PC/XT class machine couldn't be used on an AT, or vice versa, as they used a different protocol. Some were duel standard and had a switch on — I've got one.

I recently came across an 88-key keyboard that I'd forgotten about.

Now I never had an AT machine. I've obviously used this keyboard on an XT as the + key on the numeric pad has been re-labelled ◄┘, which I used to do by hacking KEYB.COM.

Today I put it on my Pentium 4 via a 5-Pin Din to PS/2 adapter and it worked. The only niggles were the \ key not working, though I managed to get it to with a re-mapping program, and nor does the ALT key. I didn't mess about with that as for all that it's a nice keyboard it doesn't feel any better than the ones I currently have in use.

What's puzzling me is that this keyboard doesn't have an 88/286 switch on so where some made auto-switching?
