drive mirror was a LCD display with the track and sector also had LEDs for half-track and
density.
from my research, the ads were in transactor and such,
but apparently none ever made it to market,which is too bad, because it's a very cool
little thing for the 1541

whatever you do, don't run it. it's not actually a copier.it's made up
to look like one, but it uses every trick in the book
Is the book available?
to utterly destroy
your drive,even little things like disabling the track check and so
forth, telling the drive to seek to track 100,which the drive would
happily try to do. occasionally making the drive sound like a jet
engine,also code from "daisy" and hordes of other things I don't think
anyone has actually looked into. suffice it to say, it has been known to
wreck drives, even with a single run.that is, if you're stupid enough to
actually run the damn thing - I wasn't, but there were people who did.
it was put out by a fake company calling itself "magnetic manipulations
Inc",which I always thought was a cool name. too bad they didn't do much
productive releases,they're only decently useful utility was called SDS
(super disk speed) - a fast loader.or I suppose "soft sector format" was
another really cool one. there were tons of these little
groups/companies doing very cool things.
Now that was more interesting. Do you have any more details about the
techniques used?
On most non-embedded "industry standard" drives, there is a SENSOR
"track0
switch", to reduce the amount of cumulative damage from hitting the stop.
Some drives had an innermost track stop, but many did not.
But, did they do anything more interesting than seeking back and forth
between tracks?
I wish I had gotten one of those "drive
mirror" LED track/sector/density
displays....
What exactly was it?
Was it like the track display that Everex put on their case?
