Yea, but those systems aren't quite pure ISA systems. They are SBCs
with an ISA interface, but with PCI NICs and built in IDE controllers.
We're not talking about breaking those. Your systems have 64MB or more
of RAM, which is enough to run FreeBSD (should you guys ever forward
port). Though, to be honest, I'm not sure if UART would work with that
particular card... All the proprietary cards that I recall should
still work, though there may be some hassle with the network stuff one
of them does.
