Given (a) that these are 48 tpi 5.25" DD diskettes and (b) that the
3B1 uses a WD2797 at standard data rates, you should *at least* see
returns from a Read ID operation. ISTR that while the 2797 could
format using a variety of DAMs, there's only one recognized MFM IDAM
and it must be preceded by three A1s to be recognized reliably.
If you're not seeing at least the address headers, it doesn't look
good.
So, does anyone know if we can count on sometime in the next few months
having a complete set of install disk images that can be written to floppy
with or without a catweasel?
This made me think of a possible alternative. How hard would it be to do
a fresh install on a 3b1, then dump the hard drive? Would that eliminate
the need to deal with weird formats? Would that be acceptable for the
different variations of machines?
Note, I have a catweasel specifically for weird formats like this.

A: Because it fouls the order in which people normally read text.
Q: Why is top-posting such a bad thing?
A: Top-posting.
Q: What is the most annoying thing in e-mail?
Does it fail to see any sectors at all?
Correct. I haven't tried a catweasel on it yet to see
what the details of the sectors are.
