Be aware most Willems will require a parallel port.
Most newer units will
also sport a USB port, but it's for power only.
Some of the newer units will indeed work with USB.
Either way, buy a unit with a socket for an external power supply. The on
board charge pump can't do enough with USB supplied power to handle all
of the EPROM programming variants.
It seems that there are USB to DB25 devices available so you can plug the
Willem into a USB port on a modern PC that does not have a parallel port.
Has anyone tried this?
