If the guy is having a problem with his parallel port A/B switch, it may
be because it's not built for EPP/ECP. I've seen EPP/ECP 1/3 switch boxes
for $25 (either in JDR's PC-component catalog or MEI pc-storage catalog),
on the same page with non-EPP 1/4 boxes for $10-$15. Maybe it has
something to do with it.
