Yes. I even got an offer. I have to see how this works out.
Yes, not as much fun
as real hardware, but educative.
Sure. It is just a mater of keeping open
eye and time.
Depends. Heads aren't *that* hard to replace.
I know. I had a quick look at the maintenance manual.
However, interchange between your drive and others can
be an issue
Interchangeability is no issue. I have only one drive and don't need
to
read / write other peoples media.
Plan B: Get a
RL11 and connect my knowen to work RL02.
That works too. RL11's aren't
that hard to find. Plan C: Build
some modernish hardware to emulate the RK05 drive.
Meh. Or even
better: Get some UniBus to SMD or ESDI controller. I have some
nice SMD and ESDI disks around. Winchester disks are so much more
reliable.
You can find those too. I don't know. I haven't had all that much
trouble (ie once I got them working) with RK05s or RL01/2s. RK05s are pretty reliable and
built like a tank so other than messing up the heads by doing something silly, it's a
pretty reliable beast.
The problem is the missuse by the previous owner, bad
storage
conditions and time. Meanwhile I removed the damaged disk from the
RK05. If I am in real luck the headcrash may be before track 0. So the
disk may be usable. But the drive needs a tough cleaning. The foam used
as prefilter and gasket is brittle. The duct from the absolute filter
to the cartridge is brittle too and has fallen into pieces already.
I need at least replacements for the pre- and absolute filter and the
cartridge duct.
I did a quick smoke test with the Tektronix 4012. Unfortunately it
doesn't work. The tube lights up in green, as usual, but can't be
cleared. The phosphor is dameged on the right edge and there are quite
some signs of bun in.
