Lunchboxes! :-) And there are images for new boot ROMs available for
those
which will allow you to boot from the on-board SCSI host adapter, ...
I've heard of this, but I haven't seen it. As I recall, the onboard SCSI
adapter uses programmed I/O (no DMA!) so it's really slow. For a TK50
nobody would ever notice, but for the system disk it's a problem. Better to
cluster boot one, diskless.
FWIW, an RD54 isn't necessary. The 2000 can easily be convinced to use
_any_ MFM drive, DEC or not. You can get VMS V4 on a 30 meg drive, maybe
even 20, if you're determined. Long ago I wrote up a little description of
all the VS 2000 disk formatter parameters, what they meant, and how to fake
them for non-DEC drives. Google ancient Usenet postings if you're
interested.
