I have an Emulex UC18 (dual SCSI, one channel setup
for MSCP disk, other
setup for TMSCP tape) on my PDP-11/44. I have both 2.1GB Seagate hard
drives and DEC RRD43 (Toshiba) CDROMs on the disk port. I've used the
CDROM to boot XXDP, RT-11, BSD2.11, and RSTS. The Emulex reads the CDROM
and reports the size of the disk as the size of the drive. If no disk is
present it reports drive offline. I can mount/unmount (BSD) and switch
media in the CDROM at will.
I'd not thought of building an XXDP CD-ROM, *good* idea! I assume in the
case of XXDP there aren't any issues with booting off of a Read Only drive?
What kind of luck have you had with RSTS? My goal is to be able to install
RSTS/E off of CD-ROM. I can install RT-11 and RSX-11M+, plus I should be
able to install RSX-11M. I got stuck on RSTS/E, but then I don't claim to
be very knowledgable about RSTS/E.
I can't remember if I've had a CD-ROM on my /44, I think the Viking UDT
controller has new enough firmware. The real problem is the /44 is buried.
I've got Viking QDT's in my /23+ and my /73.
