This is actually the first I've heard of anyone trying to use a Zip
Disk for a PDP-11. I think Jerome Fine uses MO disks. I have SCSI
drive trays (like you used to see in PC's) for my PDP-11's, and just
slide in the right hard drives. I'm using a Viking QDT SCSI Adapter
though. I also have a Plextor SCSI CD-ROM drive in my /73 (one of
the old ones that uses Caddies). I've successfully burned SIMH
images to CD-R and booted them on my /73.

I have a bootable 100MB RSX-11M image in SIMH

identical to my machine, so it should be straightforward,
but when I try to boot my disk, I get a "not bootable"
response from the ROM (the activity light on the Zip
drive does flash momentarily, so I know something is
going on, but it doesn't look like it's taking enough time
to actually seek anything (and when I boot through the
bootstrap provided by the CQD-220 ROM, I get a HALT
at 000002, which tells me it's probably getting all zeroes).
I know at least some of you boot your -11s off of Zip disks,
probably with similar cards. What am I missing? As far
as I can tell, the SIMH disk image format is a headerless
binary blob, but it doesn't look like I'm getting to the point
where that even matters yet.
