If alcohol isn't a good idea, white vinegar or dilute ammonia could also work.
Ammonia is the world's best peneyrant as far as I'm concerned. But to get into
deep crevaces and crannies it needs time. Sometimes 24 - 48 hours. It will

Doc, will you please elaborate on why you avoid the Disk Utility (.app)?

When I'm archiving disks and begin to get unrecoverable errors, I do a head
cleaning and, if the errors go away, it was a dirty head; but if they
don't, something's wrong with the disk.

For 5.25" RX50 floppies, I imaged 400 of them before I needed to clean the
drive... and even then I'm not sure it needed it...

I think people use alcohol to clean the ceramic heads. Not complicated, but
getting in there ...
You could also think about vacuuming or blowing crap out of the mechanism
before cleaning the heads.
Disks give errors, duh. Whatever you use to image a disk, use it as a first
attempt, as that

I think I've only ever seen pictures.
I would love a go at some fo these if no one of longer standing on this list
has shown interest (I only recently signed up).
Many thanks

As others have suggested, a "period correct" 8/L solution
I got the 8L pretty cheap on eBay a few years back after it had been stripped
for parts so it’s been a long restoration project this is why I’m so attached
to it. Now that I’ve learnt that for the L I won’t be running anything other
than paper tape I’m ok with that as I do like the limitations.

Well, yes-ish. I thought about it last night and realized that the
pdp8/L *does* have a data break
That will be complex. I had an RK8 disk controller (the 6 foot cabinet
that was it) along with a pair of the RK03 disk drives and it was (a)
insane, (b) heavy beyond belief, and (c) finicky.
It also required Data break which is not built into the stock pdp8/L.
You would need a BM08 box, and

The nova a 800/1200 series machine and thank you for mentioning about the 8L

sentimental value as the first machine I got and especially since it has such a
interesting history (nuclear power plant in France). Since those

Is it even possible
Hi Mark,
When I visited, there wasn't any documentation in sight and I would have
expected there to be a pile on the floor it it did exist. I will ask.
There may be a pause in this as Covid is about in the area and I haven't
heard from my mutual friend in a day or two
Regards
Chris
