Do you have any other 32 bit little endian NetBSD boxes about?  It
should be simple to get my hacked-up version of mopd running on one of
those boxes to netboot your /240.

No idea myself - I'll add it to the FAQ if anyone knows.  I _suspect_
that the PROM might be on the CPU daughter board.  I _think_ we've
replaced /240 boards with /260 boards and ended up with different PROM
versions.  I haven't got any apart to double check this...
