don't be such a dick. he's said why he needs older machines.
for the OP.
check out VMware, you can use vmware player and run windows 95, and pass through access to hardware (I assume parallel port). -and that software is free.
You can still buy expansion cards (that have both parallel and serial) in shops, (in the UK Maplin sell them in store). these are usually PCI cards so will work with modern machines.
it's also possible to get USB to parallel converters, but these are A pretty rare, B pretty buggy since there is no real flow control on the USB port as there is with the parallel port.
