Hmm... I happen to have a 486DX33 that's has both ISA fingers and
PC/104 sockets. No integral Ethernet or video, but has
serial/parallel/ATA. If I can find a way to get even 10Mbit Ethernet
on it easily, I've contemplated using it for a little network
peripheral box, but it'd also make a nice emulated RX02 like yours.
One thought was an "ISA staple" board - two slots - one for the CPU,
one for a NIC. It still wouldn't be too large to be convenient. Not
as nice as one board, but much nicer than a full-on cased PC.
And what sort
of daughterboard (PC-104?).
Not PC/104... Yes, this one is similar. It can take PC/104 and
PC/104+ boards,
and the SBC itself can plug into a passive 16-bit ISA backplane. I
always found it odd that a board that has PC/104+ (which is PCI on a
different connector) capability would have an ISA card-edge connector
on it instead of PCI.
That does sound strange, but perhaps it's designed to work with older
backplanes as an upgrade.
Is it DiskOnChip(tm)? Many SBCs can take those,
both early and
modern. I have a small pile of them somewhere.
I will have to check, but my 486 SBC might have DoC... How expensive
would a 16M or 32M chip be? One can fit JAILBAIT or Damn Small Linux
in that (or Linux Router Project in under 2M).
