That occurred to me also--it seems so obvious that I passed mention of it. But PC 5150/5160-type keyboards use a very different protocol from 5170 and later keyboards--and they're not interchangeable. Some early AT-style keyboards can be configured for either mode (e.g. the Keytroics/Honeywell KB101), but if you're going to use a AT or PS/2 style keyboard with an XT-class machine, you'll need a converter. --Chuck
