I think what I'll do at this point is try to make
an image with
exchange of v5.03 with my program and all, and copy as well as copy/boot
it to a scsi disk on the vax, and then move it to the PDP. Assuming I get
far enough to get that working, I'd then experiment with getting it on the
CD. I did end up coming across a Viking/QDT SCSI controller, but it
doesn't have bootstrap, and I don't have a BDV11, nor do I have room for
one. I may buy a CQD-200, as they are a lot cheaper than the the CQD-220.
I'd be willing to trade the Viking if anyone wants to swap.
While not as fast as the CMD controllers the Viking/QDT is a good solid
controller. What version are the ROMs on it? You need a fairly new
version to support CD-ROMs. This is the controller that I use on my
PDP-11/73 (in fact I just booted off of CD-ROM this morning). I know for a
fact that it will talk to a DEC RRD-42 CD-ROM (which I like since it's a
caddy drive).
Before I got the Quad-Hieght /73, which has onboard bootstrap and console
port) I had a dual-height /73 without the onboard bootstrap. At that point
I had a WQESD ESDI controller in the system whose only purpose was booting
the system and a DLV11J for the console port. I've still got the DLV11J in
there as well as a RQDX3 in the system that's only there to drive the RX50
floppies.
