Perhaps you've been skipping the recent thread where we've been
beating this topic to death?
Ahh. I meant that I thought all PC-type machines *with a parallel port*
present it to the system as though it were an ISA-connected port (as in the
original PC) and *not* a high-speed I/O port running at close to the system's
main bus speed - i.e. using a new machine with a parallel port doesn't give
you any speed advantage over using a machine from ten years ago with a
parallel port.
That could well be wrong, in light of what Chuck said. I know that more modern
ports are capable of higher rates using different modes - but I thought those
were purely for point-to-point data transfer between port and device, and not
really suited to twiddling individual port lines at high speed. BICBW :-)
Finding a new system with a parallel port is a separate challenge. I miss my
old Thinkpad laptop as there's no useful ports on this crappy Dell :-(
