One of my co-workers a while back, and gave me some old electronic stuff
he had in his garage... among the items was a relay board from
Keithley-Metrabyte (I think), and an ISA card with an 8255 on it. The
relay board has a power supply, 24 relays, a couple of relay drivers, and
a connector to interface with the 8255. It was pretty easy to get it
working on NetBSD/i386, using some asm("outb")s and the stuff in libi386.
