I haven't worked on my M.2 for a long time
(since I first got it about 3 or 4
yrs. ago, and I'm also missing the cables for the 3 HDs) It was
recommended by several people that I transfer the programs I have from 8" to 5
1/4 disks (unless bit-rot has already got to them) and I believe there's a faq
on how to do that. Do you know if the disk controller on the model 2 /16 is
the same as on the other RS models ? If so possibly I could just transfer them
to another format.
The Model 2/16 is MFM, with a 500K data transfer rate.
The Model 1 is FM with a 125K data transfer rate
The Model 1 with "doubler", and Model 3/4, and Coco, and M100 DVI, are MFM
with 250K data transfer rate.
All seem to be Western Digital, with reasonably "ordinary" format, except
for D.A.M. issues with model 1.
What you COULD do is to cable a 5.25" "1.2M" drive to the Model
2/16. When using 600 Oerstedt disks (aka "1.2M"), it doesn't have to know
that it is no longer talking to an 8".
Undoubtably the 8" disks would copy
(discounting bit-rot) and I have seen it
mentioned on disk recovery sites but I can't afford thier high prices. It used
an early Shugart SS/sd(?) 8" disk. I guess it would require some sort of disk
image program for 8 " floppies.
WHAT are you referring to?
Reading disks with another machine? Reading the disks with that machine and serial
transfer?
No, I don't have a serial communication program for it nor any of the
hardware.
Was there any disk image program for the model 2
?
WHAT are you referring to?
Software running on Model 2 that could read raw sectors from disks
from other machines? Software running on Model 2 that could read files from
disks from
other machines?
Ok, but likely not possible.
Software running on Model 2 that could create a raw
file of the sectors of
a Model 2 disk?
If that was the only way of transferring the m.2 disks to a newer format
ok, but that wouldn't answer my problems with transferring the MICOM
disks to another format for preservation.
Sorry if I didn't make myself clear.
