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.

That does sound strange, but perhaps it's designed to work with older
backplanes as an upgrade.

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).
