booting from RQDX3

So far I have never seen a third party Q-bus disk interface card that
did _not_ include a PDP-11 boot rom. I'm sure they exist but they
weren't made by the 'name' brands (CMD, Dilog, Emulex, etc) The funny
thing is that the boot may consist of four 64 x 4 TTL ROMs which look
like any other chip.


P.S. Does anyone know if you can convert a CMD CQD200/T into a CQD200/TM
? I like that it can talk nice to my exabyte but it would be even nicer
if it could talk nice to my disks too :-)
