I've come up with a way to read Heath hard-sectored disks with a 1797-style
controller (with some modifications). I've now archived all of my old disks
with only one unrecoverable error in an unused sector (not bad for media that
is approaching 30 years in age). I do seem to have run through *drives* at
an alarming rate, though I hope that the cleaning disks I have on order will
restore some of them. Is anyone interested in:
-Technical details (the method should work for many non-standard FM formats)?
-Having me read any H8 disks?
-Any distribution images that I might have?

I have a huge cache of H8/H89/Z100 software, half a room full at the least
(the other half of the room being documentation for same). Where are you
located? I'd rather not ship it all, but would welcome someone to come over
and archive the bits. I believe I have a wall full of Magnolia drives, Heath
8"FD/HD combo boxes, etc.
I would bet I have more than a few spare hard sector drives as well, many
new in the box. Someday I'll get the time to go through my Heath holdings...
a project for my retirement no doubt :>

Hi Dan.
By all means, please post some technical details.

Nice to see you on this list, Dan! I remember your advice
from the BAWUG list. In fact, I seem to remember
referring
someone from this list to you - someone looking for old
ISA wireless gear.
Dan's a clear expert on old Aironet wireless gear and apparently
old Heath equipment!

New subject: Teledisk problem
Maybe someone with experience using Teledisk can help me with a problem. I
have an 8" drive connected to an IBM PC/AT floppy controller, with the 34 to
50 pin adapter. I think it's working correctly when making a file from a
disk, but I can't be sure because I can't recreate the disk. It gets to 32
sectors and can't find anymore. I have a similar problem trying to use
Anadisk to format an 8" floppy. I set it to 48 sectors, but it only writes
out to 32 sectors.
Anyone ever see this kind of problem and know how to solve it?
Thanks,
Richard Lynch

My recollection is that you need to use something like a CompatiCard instead of a
standard FDD controller for the 8" drives. Something about controller BIOS?
Perhaps someone else with clearer memory (no pun intended) on this subject will comment.

What disk format are you trying to create? Nearly all PC floppy
controllers (and probably other controllers, too) can't handle more than
32 sectors/track. I've found one that could do more (up to about 50) but I
don't remember the type right now (maybe a DP8473). Other things that
could cause problems are the GAP sizes which can't be made too small. I
tried it when I wanted to create 52 sec/trk MFM disks, although 26 sec/trk
FM works fine.
