Hello:
I'm working with the Computer History Museum, Mountain View CA, on a
project to identify significant disk drives - the RP01 and RP02 have
been so identified. Would anyone on one of these mail lists have any
knowledge of any such drives still in existence, operational or not?

The Computer History Museum site shows the
Memorex 660, aka DEC RP01/02, as the
"First OEM disk drive shipment to Digital":
[url]http://www.computerhistory.org/corphist/view.php?s=stories&id=159[/url]
630-1 (RP01) Disk Drive (link)
Isn't that wrong or a mis-statement ?
I thought the Diablo/DEC RK01/02 came
before the Memorex 660.
It might be easier finding a 660, since it
was oem'd by several different manufacturers.

If I'm not mistaken, the Memorex 660 was the drive used in the RP06. I
think the Memorex 630(?) was what was used for the RP01/2.

I believe Diablo shipped well after Memorex.
The RP02 is the 660-1; DEC was by far the largest customer, including
many of Memorex's end user versions, the 660-0, which were converted to
660-1's and sold to DEC to become RP02's.

The Memorex 630-1 became the RP01
The Memorex 660-1 became the RP02
The Memorex 667 became the RP06
ISS did the others.

I seem to remember seeing Ampex on the RP04. (But I also remember seeing
ISS on *something*. Or was ISS and Ampex the same company? I distinctly
recall seeing the name "Ampex" on some disk drive and thinking, "Oh, those
are the guys who build the big studio audio and video tape decks."
Also, the RP05 was pack compatible with the RP04, but looked just like an
RP06, so I think they were also Memorex. (And I do remember seeing the
name Memorex on RP06's.) I don't think I ever saw a real RP01/02/03, just
clones.
No idea which was first, the RK series or RP series.

I don't remember seeing RK02s before RP01/2s.

RP07 wasn't a Memorex? I'd always assumed it was due to the RP
designation. (Maybe it just worked with the same controller?)

I can't help with the "which Memorex model was it" question, but we
(Cyphernetics/ADP) had RP-01s by the end of 1969. I don't think there
were PDP-11s by then, much less RK01s.

RK01 was from IOMEC, used on the RK8 (not RK8E)
RK02/03 are 1100/2200tpi Diablo drives.
Drawings for the RK8 are from late '69 early '70
The printed documentation for the RP10 1st edition is
Nov 1969. The drawings in the manual don't have a date
I could ask the RP10 designer the exact dates the next
time I see him (he is a CHM volunteer).
RP03 is an ISS drive. I don't recall any Ampex drives
being sold to DEC directly, though many OEM systems used
them, including the AED 8000 subsystem (I worked for AED
in the early 80's).

Yes thats where I first saw the RK02/03 on PDP-8's, Diablo
drives and the was company later bought by Zerox IIRC.
Late 60's early 70's maybe.
As a field guy the RP03/04 ISS (Sunnyvale I think) drives
were better drives more reliable and easier to work on.
I used to work for Ampex and repaired their DEC
compatible drives (SMD) but I don't think DEC ever
oem'd them.
If memory serves me right the 660 (RP02) was the
only drive you could "tune" by ear. In the field the
quick way to do a radial/azimuth alignment check
(with no scope) was to do a repeated full track seek
and listen to the noisy mechanical detent drop as each
track was reached. You could then tweek the drive
or pots till you got the right "sound". Customer used to
love it. Non factory approved method though.

The RP05 was originally called the RP04-II (a half density RP06 designed
because the RP04's were not the most reliable things DEC ever had in the
field... But they did beat the TU45's by a bit.
The RP04's liked to blow driver transistors and such so the DEC folks
were looking at the RP06 and another Sperry ISS drive and chose the RP06
and came up with the wider head reduced capacity RP04-II (named RP05
after the marketing folks realized RP04-II would be confusing).
Anyway, the RP06 class had one of the remaining RP04-II prototypes for
the field service training class demo drive...

Was the RPR02 an ISS drive? I thought so. I thought it was their first
sale to DEC (although it could've been the RP03...)
DEC went back to Memorex after the RP04... and used CDC's for the
RM02/3/5 drives. The RP07 was also an ISS/Sperry product.

Been a long time since RM and RP06 classes.

The Digital RP05/06 Field Handbook
(company confidential) says:
"...RP05/06 consists of a 677-51 (RP05) or
677-01 (RP06) disk my Memorex with a
DCL by DEC...."
The RP04 IIRC was definitely an ISS drive.

So here is what we have:
RP01 Memorex 630-1; equivalent to IBM 2311 (7 MB); shipped late 1968 (I
know, I shipped it);
RP02 Memorex 660-2; equivalent to IBM 2314 (29 MB); shipped early 1969
(ditto);
RP03 ISS equivalent to double density 2314 (58 MB)
RP04 ISS equivalent to IBM 3330 (100 MB)
RP05 Memorex 677-51, equivalent to IBM 3300 (100 MB)
RP06 Memorex 677-01, equivalent to IBM 3330-11 (200 MB)
RP07 ISS equivalent to IBM3350?? or maybe just a 50% increase over RP06
(300 MB)
[MB capacities are in million bytes in the IBM full track record
format]
FWIW, the one salesperson who sold most these products to DEC was
Arnold Cooley, working variously for Memorex and ISS. Also there are
two operational RP06's at the PDP-10 project - probably the oldest
operating disk drives in the world.
But, has ANYONE SEEN AN RP01 or RP02 recently?

NOPE, not me...good summary though....
still unresolved, what was the
DEC;s first oem'd disk, Memorex, Diablo
or something else....

You could probably get some dates for the others by looking
at TW's (Tony Wachs) sources in TOPS-10 monitor listings.

The RP07 was a late 80's Sperry product in the 450+ mb range used to
fill the gap before the RA81 came out in numbers.

Not to belabor a point, but I seemed to
Remember some "first time products", in the
11 and 8 world, being shipped out of
CSS before becoming a production item.
I worked out of the DC area office and we
Installed a lot of CSS hardware at the various
Military and spy agencies. Later they would
Become production products.
I remember the DT03, DX11-B and several
Others as originally CSS products than later,
I think, they became Part of some product line.
Additionally the DEC compatible companies would
Beat DEC to the punch with new devices in the 11 and
8 world. I remember a company out of Texas that had
a hard drive for the PDP-8 but can't recall their name.
Maybe a CSS or plug compatible device can lay
Claim to the first disk drive, but not the first oem'd
drive ? Maybe not.
