I'm fairly sure it's really a software issue related to timing - I
suppose there could be genuine hardware limitations (speed wise) with
some of the early chips-although I doubt that bus speeds were fast
enough to bring those limitations into play.

The Cordata/Corona Data Systems laser printer interface card
is for PC/XT. Attempting to install the software on 286 or
above gives a message telling you not to, and mentioning a
286 version of the board that may or may not have ever existed.
Is the hardware actually incompatible?
Or is it a bogus test by the software?
