Hi Chris,
I’m located in Boulder, Colorado. I’m fine with an RL02 that doesn’t work. If
it can’t be fixed it can always occupy space in the rack. This is going into a
museum and I might end up using an emulated drive behind the scenes for
day-to-day use.

If you have the version of the RL02 that can be jumpered for either
RL01 or RL02 use, yes. I've seen people put switches on a plate under
the lid (over the old brush area) so that you dismount an RL02K, flip
the switches, mount an RL01K, then read it. One of the tricks is to
be sure to
I bought a pair of absolute filters for my RL02's. Good idea as one was
so plugged the heads could not fly.

Are they? Since I have had several of them since the 90s, I've never
tried to go buy more.
What's rare to me is RL01/RL02 absolute air filters. Finding a way to
repack the guts with new filter

If you have the version of the RL02
If you really want to fix an RL02 I have a pile of parts that equal a
RL02. Good spindle, power wires were eaten by mice, good electronics,
weird heads, good head servo system, good motor, etc.
That way I'll be forced to get the RL01. To fill the void in my life.
Where are you?

God, $140 is quite reasonable. I keep thinking of picking it up but then
I realize I can read my RL01's with my RL02's if needed, then move the
data to bigger disks.
But RL01's were great for running RT11 and other base operating systems.

Well, there's this:

It's an RL01, not an RL02 as you were enquiring after, but RL02's are
I can't help you with the RL02... But I have MFM drives, experience using

Looking for a pair of DEC RL02 drives, working or otherwise, for a PDP-11

fine if it's not working - I'm happy to try and get it up and running. Thanks!

Hi,
It it possible to get parts for a Digicomp? Mine needs some springs and
the thing that connects the clock to the whatever.
I used rubber bands instead of springs.
The article about 3D print DIY
https://www.thingiverse.com/thing:1477209
contains instructions how to bend the wire crank.

That is very cool!
The RICM has a DIGI-COMP, but we have not done much with it

In fixing my PSU I managed to break the leads to the LED on the front of the
PSU, probably through metal fatigue.
I seem to remember people saying it is quite difficult to replace these,
mainly because you can't get them out without breaking the holder. Is that
right? Has anyone done this
