I need a system disk badly. I posted on some news groups but got no
answer. If you have one, would you please make a system disk for me? I
will appreciate it and pay your cost.

Oops, now that my memory is returning, the RK02 was the same geometry
but half-density. RK02 carts say "1100BPI", RK05 carts say "2200BPI".
Was there a RK04?
==
page 1-1 of the RK11-C manual (RK11-C_manual1971.pdf)
"The high-density option provides a choice of either
the RK03 Diablo Disk Drive Unit or the RK05 DECpack
Unit, both utilizing the RK03-KA, IBM Type 2315 12
sector high-density disk cartridge. The low-density
option provides a choice of either the RK02 Diablo
Disk Drive Unit or the RK04 DECKpack Unit, both
utilizing the RK02-KA IBM Type 2315 12-sector low
density disk cartridge".
low density is 12 256 byte sectors (1100 bpi)
high density is 12 512 byte sectors (2200 bpi)
both are 203 cyls, 2 tracks.
I can't imagine there were many RK04's made..

I was under the impression these were RK03s.

The disks have a "-8" designation on the edge, where the RK05s have
the -16. So I am guessing they are half the density of an RK05 pack?
I am still trying to get these to work. Something happened during
transport. The drives operate somewhat, although a bit flaky at times
it seems. It could be something with the controller too. I am waiting to receive the hardcopy of the rest of the documents for this to figure out the problem.

I got a bounce while trying to mail you today. If
you're still on the list can you mail me a working email
address please?

I'm going to take you up on your offer of reading the GUTS
RK05 pack, if we can arrange the delivery. My old Dad
has volunteered to hand-carry it as far as Brugge if you
can find someone who can meet him at the ferry there?

This morning at work (auto repair shop) the scrap metal guy drove buy
with this printer on the back of his truck. I did not get to it before
one of my techs had gutted it for the cabinet. I was able to save the
printer carriage assembly, what I think is the logic unit, and the power
supply unit with the copper ribbon conductors intact. Are these parts
worth saving, and if so, is anyone here interested? The power supply
weighs in at 61kg's the printer isn't light either, maybe 20kg's so
shipping is probably not practical. I can only hold them for a week or
two due to a lack of space here at the shop. Thanks for any advice.

you appear to have an HP 1000 A-series and a 7914 disc/tape combo.
in theory, you should be able to boot from the disc, assuming
there is anything left of it since the heads probably weren't
locked when it was moved.
the software would have been loaded from the 1/4 cartridge tape
but it doesn't look like you got any of those.
it would be a good thing to read those HP 1/2 distribution tapes
that go with the other system. jotting down what's written on
the labels will reveal addtional clues on how the systems were
used. they were probably running RTE-A on the A700 and some
version of 6VM on the 1000Fs

I may have the A-series CE manual. A and L series are sort of
new relative to the manual archive that was saved.
