Now here's a tricky question: If the SE30 were
the only mac
in my entire household, how would I procure an OS install on
diskette for it? The drive in that thing is the 800K
multi-speed beast, yes?
Do you have a PC? Apple does (or did) offer the OS's on their website,
and there were instructions about how to use various PC based programs
to write them in a Mac 800K format from a PC drive.
Somewhere I have the images and software because I've had to do this
once.

The 1.4M Mac format can easily be done by a PC with special software.
I'd LOVE to hear from anybody who is successfully formatting and writing
GCR with a PC (without adding in a "flux transition" based additional disk
controller (such as Catweasel or COPYII Option Board)
It is "impossible". (VERY difficult)

The bigger problem isn't that it's GCR, but rather that it's also variable
rate GCR. I'd remove the quotes from "impossible" on this one, although,
maybe with a razor blade and a magnet and a VERY steady hand...

How fast can you turn the MOTOR ON line on and off? :-)

I don't think it can easily be done either. Another odd thing is that the
68K machines equipped with superdrives can reliably make 800K disks from
images, my perfectly good powermacs have problems doing this.

Writing? Yes. Reading? Not if you emulate a floppy controller with your
parallel port. Google "disk2fdi" for a working program.

Disk2fdi is, indeed, remarkable.
(BTW, it does NOT appear to "emulate a floppy controller with your
parallel port"; It appears to be sampling the raw data lines of a disk
controlled by a normal FDC, and using the parallel port to provide some
of the functionality of a "flux transition" board)
Producing a version of it that can WRITE will add a few more
serious complications.
But I still don't believe that APPLE ever provided a way for a
PC to format and write 800K GCR.

Actually, not all that different from a Catweasel, only that the host FDC
is used to handle drive stepping and that there's no buffer--and the thing
can't write. Catweasel on the cheap, I guess.

Here's my question to throw into the ring:
I have a LOT of Macintosh superdrives from early NuBus PPC Macs that I've salvaged.
Is there a good spec for the interface and has anybody gotten anything but a Mac to talk
to those drives? If anybody needs a superdrive or two for the cost of shipping just
holler, btw.
