Hmm, fair point I guess. And no hard disks present as I'm network
booting everything, so I don't have that to worry about either. I need
to do some tests in a bit and work out how many boards I can drive with
one supply (main concern will be hitting limits on the -ve rails I

There seem to be quite a variation of 486 motherboards out there in
terms of keyboard socket type / bus connector types / whether they have
onboard COM ports / type of cache memory used etc. - I'd forgotten what
a range there was. Getting sufficient quantities that are roughly the
same might be harder than I thought (onboard COM ports and the same type
of keyboard socket on all of them would be nice!)

I've just been given one board that has 16bit ISA, PCI *and* VLB all on
the same motherboard, which is a new one on me.
