Hi everyone
I've posted a few times over the years about RL02 drives and my
difficulty getting them working (no luck so far!). I've spent the past
few days working on one of them and have made some progress.
The status currently is that the heads will load, and the ready lamp
flashes as the heads wobble back and forth very slightly,
I dropped an RL02
cartridge, and needed to get it to load
one more time to get programs off it.
The ready lamp was a dim, slightly flickering glow. I
figured the platter had been knocked off center.
I loosened the bolts at tapped it a bit until it looked
better centered. It took a couple tries, but then the ready
light came on fully bright, and I was able to mount the disk
and read it.
I don't know if that could be your problem. If you get a
solid servo signal with the motor disconnected, then this is
not the same problem.
To add my two cents, I've also seen this behavior on RL02 packs that have
been degaussed. It might be worth your time to find someone with a known
working RL02 drive (or known working RL02 pack) so you can confirm that
your packs are good.
