Pretty much. I took apart my VT52 about 2 years ago because it wasn't
happy. Turned out the +5 and +15 volt supplies were good but the -15 was
bad.
After fiddling around with capacitors and transistors I took the easy
way out and just put in a 7815 regulator, bypassing the old -15 volt
system
To test the false "Write-protect" error, try:
Put a BLANK floppy in the drive, and ask Windoze to FORMAT it.
For simplicity, choose the "360K" or "720K" format.
See what if any errors that generates.
If no errors (or certain specific other ones), then we can assume that the
problem is not with t
Does anyone have anything on the jumper settings for this drive?
I would like to jumper it so it can read DEC RX01/RX02 floppies.
I am looking at being able to read disks on a non-DEC systems
but I would also like to be able to use it on my Andromeda card
in a real PDP-11.

Rod, My memory is that programs like
putr need to run on "real" DOS, not a
DOS window. So if you are trying to
run putr without booting to MS-DOS 6.2
or older, that could be the source of
your problems with it.
