Does anyone know how to remove the side skins on an SGI Origin
(specifically a 2200 deskside cabinet). The manual mentions removal of the
top and front, but says that the sides are more tricky and to contact SGI
for the procedure.
I'd like to remove them as there's some minor paint splatter on them, which
would be much easier to deal with off the machine.
I see there's a screw at the bottom of the machine on the rear edge (much
like the one for the front which releases the front skin), but removing it
doesn't seem to let the rear plastic molding drop in the same way, and I
assume this needs to come off first.

I have a VAX 4000-300 that I want to pass on as I don't have room for it.
It is in a BA440 enclosure (marked VAX 4000-400). The CPU board had a
couple of problems, the levers that are used to push it into the slot have
been broken, however it will push into the slot OK and work. The onboard
Ethernet (SGEC) is also not working, but I have included a DESQA so you can
network it. It has 64MB of memory (2x 32MB). It also has a CXY08 board.
It does not have any disks because I want to keep the few DSSI disks I
have, however I will include two DSSI covers. You can still boot it as a
satellite of course. In fact I was toying with the idea of putting a
Raspberry Pi inside the enclosure with a crossover LAN cable and running if
off SIMH on that.
It is free, however I would appreciate a small donation, as it has cost me
money to collect it to save it from being dumped.
It is in the UK, in South Manchester. Although I am currently working a lot
in Coventry so could bring it to that area. I will also be at DEC Legacy in
Windermere 11-12 April, although I would prefer to leave room in my car for
the machines I want to exhibit, if possible.

More computer-esque things looking to be identified. Some of it military,
some of it not.
What might the paper tape reader have come out of?
The big circuit boards say "Harris" on them.

Err, I thought RL02 packs came pre-formatted (at least, the low-level stuff
like sector headers, etc), and could not be field re-formatted? Or are you
simply talking of a high-level re-format (i.e. the file system), which might
write all data blocks to zero or something, thereby getting rid of the
un-readable contents of such blocks?

The obvious place to put it is on our Wiki, of course... (Hint, hint... :-)

I've gotten my RL-02 -> USB Mass Storage controller mostly working with a few residual gremlins. Specifically, I've noticed from my testing that I have good packs, ones that read out almost the same every time, and bad packs, ones where half the bits seem to be in different states every time I read them. I've left write support untested until I can solve this problem.
Right now, my working theory is that different controllers had slightly different timing characteristics, and I may need to adjust more of my DPLL parameters dynamically to deal with that (something I'd rather avoid). Of course, most of these packs haven't been put into a drive since the mid-80s, and there could be some bit rot going on.
As many of you have much more experience dealing with these drives than I do, my questions are:
- What type of long term reliability have people noticed from their RL02K packs?
- Is garbage data sometimes normal for certain packs until they are rewritten with ?fresh? data?
- Has anyone noticed pack compatibility problems between various computers/RL-02 controllers?
Thanks,
Christopher

I would try gluing an extender piece on the end of the existing capstan roller, perhaps
using wood which is easy to shape. Once you wrap it with a piece or two of heat
shrink tubing, I would think that it would all stay in place.
We just sorted and shelved the following boards, most of which I will never
use. If you are interested in any or all, feel free to make an offer off
list.
There are a few non DEC ones I have to figure out yet, otherwise this
should be most of them.
If you need L boards not listed here, let me know. I have a friend who
has some.
Quantities available on most.
Thanks, Paul

Tape? Not that I know of. In principle iSCSI can handle tape, but I don?t know if it?s been done at all, never mind in Linux.

Hey all --
I'm looking for an image of the EPROM on the CMD CDU-710/M or /TM UNIBUS
SCSI adapters. The 720s have been archived, but only the /T (tape only)
variants are imaged for the 710...
Anyone out there have one of these boards and be willing to dump the ROMs?
Thanks in advance,
Josh
