"Old PC" emulation ?

[Dave Brown]

I've not come across it with serial ports but it's a common problem 
with older hardware that connected to the system bus- I have several 
older GPIB cards that won't run in anything later than a 286 and an 
EPROM burner card that won't operate in anything later than a genuine 
XT.
