  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. 
Hi
 For serial, it might be that one just needs to keep windows
...
 from fiddling with the port when another program is
using it. This may not be a processor dependent issue.

Another person wanted a 486-66 for a Massspectrometer

I know there was a problem with games that were written using the system 
speed to time loops, I guess this also occurred in test equipment.
