Vaxhaven's AG-PXL1A-RE.iso is 236013792 bytes, Winworld's "VMS 552h4
VAX.iso" is 205508764. Neither can be burnt by MacOS directly from the
GUI. The following command line results in a "raw" burn (remove the
-testburn switch to enable the laser).
$ hdiutil burn -testburn -imagekey diskimage-class=CRawDiskImage -speed

The Vaxhaven raw burn does not boot. I will try the Winworld version
next. BUT, just to make sure the RRD42 is not the problem, here's a
couple of questions about it:
1) I have connected the SCSI cable at the bottom and a terminator at the
top. Is this okay?
2) When I insert the caddie in (with the CD in the caddy), the green
light turns on for a few seconds and then turns off. Nothing else
happens. MicroVAX comes back to ">>>" prompt after a few minutes, no
other messages. Should I expect to hear some noises of the plate at the
bottom of the caddie moving sideways to expose the CD to the laser, etc?
Also, even if I get to a point where I boot into standalone backup, how
am I to fix the problem with DKA100's contiguity issue?
The previous owner said he had actual PAKs that he could not find, but
are loaded in the LMF databse. I would very much like to at least be
able to copy the LMF and am averse to reinstalling a fresh copy of VMS
on DKA100 (everyobdy here will understand exactly why this is
super-important now).
I haven't tried burning but I used p7z
through File Roller on a Linux
Mint system. I have only used it as an image on Simh. I am not at my
computer tonight but if you need it tomorrow I can get you a checksum
on the unzipped image.

Okay. Maybe it's a difference between Linux and macOOS.? I downloaded
the file from WInWorldPC.? The actual file came from someone named
"Ricky" in Germany.? The file downloaded was "DEC VMS 5.5-2H4 (Jul
1993) [VAX] (ISO).7z"? I ran it through "TheUnarchiver" and it
produced a folder with two files.? A txt file and "VMS 552h4 VAX.iso".
I tried burning that ISO file but then I get the disk image is invalid
error.
I'll have to get a copy of SimH running on my Mac and see it it can
read the ISO.

and I tend to agree that the VAXHaven one is corrupted (at least it's
never worked for me). But the WinWorldPC copy works great. Also,
corrupt is the MicroVMS 4.7 TK50 image on VAXHaven.

??? The file I got from WinWorldPC came as a ".7z" archive.? and I
unpacked it with "TheUnarchiver".? Does that match what you did? The
file I get from that always gets the "Could not burn "VMS 552h4
VAX.iso". The disk image is invalid." error from the Mac disk burn
software.
??? Did you do something differently?
??? Thanks.
