Hi,
So.. what it boils down to is: is there any
(serious) project on doing
a "old pc systems" emulation a la SimH, which does, for example, a
pure IBM PC, PC/XT or PC/AT ?
I had a request yesterday for a 286 or earlier machine, the person says
that somethings with the serial ports changed after that and the test
equipment gets communication errors on newer machines.
I expect that it's due to a timing issue. The HP-IL card that HP made
for the PC has the same problem.
I strongly suspect that "PC"s are getting old enough and scarce enough
that they will shortly be valuable again.
