that.
You don't have a random Linux box there with a SCSI interface?
What about the Netra T1-105? That'd do it.
It doesn't have the correct SCSI interface...I don't have any adapters

Ahh, screwed by The Connector Conspiracy. :-(

Yup. Same damn protocol, different interfaces.

That generally has no correlation whatsoever. What's important is
whether
or not the CD-rom can read the recordable media you're using. Some
record-
able media works better than other in older CD-rom drives.
Hey, I haven't touched CD-ROM stuff in awhile! ;)
You need a refresher...
BTW, the drive you have installed, is it jumpered for 512 byte
blocks???
I'm not even seeing a jumper for it on the drive. Drive is a crippled
Apple CR-507-C (Hey! It's the only working SCSI CD-ROM drive I have!)
I wouldn't be surprised if your problem turns out to be related to the
block size. DEC machines wants disks (including CD) to have 512 byte
blocks. A majority of CD drives do 2048 byte blocks. Not compatible.
Johnny
I think I have several 512-byte sector drives! None of them SCSI...
The drive burning the images is 2048-byte...that'd explain the problem.
No. The writing is fine. You can write the data on any drive...
You need to read it on a drive that do 512 byte blocks.

I don't think this is a problem. I've burned many VMS images on my Mac and booted my VAXen from them.

Dave -- might want to tighten comment that a little. GNU-emacs builds
on most anything with a 32 bit linear address space or greater. Other
emacs implementations YMMV.
In addition, a port of Emacs is actually not that trivial.
Anyone familiar with TOPS-20 (or OS/8, or probably some other of DEC OSes) will probably recognize what I'm going to write next.
Emacs "knows" how an executable looks like, and how the memory layout is of the running program, and how dynamic libraries work, and so on. Because, as a part of building emacs, emacs will start bare bone, read in all kind of initial lisp packages, compile stuff, and create a finalized emacs in memory that is running with all the bit and pieces of initialization code already run. At that point, emacs will do a memory dump to disk, and munge that file to be an executable. And that is the actual emacs binary.
For any new system, and especially for any new binary image format, emacs needs to be taught all about it.
But anyway, if the scope would be "emacs" and not "GNU emacs", then implementations exists for just about everything. I've written a small emacs-clone in TECO-8, there exists multiple Emacs clones for MS-DOS (maybe the best known is Epsilon). Stacken (the computer club at the Royal Institute of Technology) wrote an emacs clone called AMIS, which ran on VMS way back, as well as on Tops-10, RSTS/E, Norsk Data machines, and god knows what else.
There is MicroEMACS, which is really easy to port around (I have it running on RSX).
2BSD have JOVE.
I'm sure people can easily come up with other implementations...

If it doesn't have a physical sector-size jumper, it won't work. I've never met a compatible drive that didn't have the jumper. By the way, this is the same type of drive needed for an old Sun Sparcstation, if you have one of those lying around...

Eh... And... The speed you write with have no relation to the data eventually ending up on the CD, nor the speed you read them off. The speed relates to the time it will take to read/write the disk...
Johnny
Ahh. I assumed it was something related to timing.

Actually the statement holds quite well for anything people are likely
to run into, and certainly everything we talk about HERE save for
PDP-10s and PDP-11s. No, not a Commodore 64 or a PDP-8, but let's be
reasonable.
