I'm mainly interested in Unix-Workstations.
I currently have access (I don't own most of the machines) to:
various RS/6Ks
various SGI-Workstations
a few Sparcstations
two VAXstations
a DEC 3000
I don't have access to a "HP Apollo 725/50" because the PSU died
and is beyond repair :-(
Does anyone know the Voltages on the PSU-Connector and
if a standard PeeCee PSU can be connected to it...
I'm also tinkering with some transputer-based systems...

I don't know what elmers glue is, and I don't have an HP41C or HP200LX. If
the case is plastic, it's most likely some grade of ABS or just possibly
PVC. (If it's a "waxy" plastic it may be some relative of polythene or
high density polypropylene and almost nothing glues those -- you have to
heat weld them.)
Proper ABS cement (available for plastic plumbing) is about the strongest
glue you can get for that, much stronger than superglue on ABS. It doesn't
just adhere, it welds the plastic. An alternative is methyl ethyl ketone,
MEK, commonly available as a solvent and widely used industrially to
glue/weld both PVC and ABS.
Whatever you do, try it on the inside first, where it won't show if it goes
wrong!

The usual concern is not capacity -- if the school already has copper it
probably is 10baseT or 10base2/10base5 which is the same speed as 10baseFL
-- but safety.
You're not supposed to run copper between buildings for two reasons. First
is that they may not be grounded at the same potential; there could easily
be a voltage difference between them. Even a small difference can cause
damage to interfaces, though if they're working at present, presumably
that's not serious in this case. Tiny differences just cause increased
error rates. However, if there should ever be an earth fault on one
building, all bets are off.
Second reason is inductive pickup, or change in ground potential due to
nearby lightning. Even coax picks that up rather well.
The cheapest way to do this is often to find a pair of hubs (like the 3Com
Netbuilders or PSII range) which can take an extra transceiver module or
two in the back. They're usually cheap, and the Fibre Link interfaces are
very cheap because hardly anyone wants them. Standalone media converters,
on the other hand, are much more expensive, even secondhand.
Best way to buy the fibre for short runs (10-50 yards) is to buy patch
leads from a trade supplier. Trade suppliers are typically 1/2 - 1/8 the
price of end-user catalogues. Better still, sometimes you find people with
surplus patch leads with ST connectors, which they've replaced with SC or
even MT-RJ.

It's not, but that's OK, the 200LX is a classic computer anyway.
Do a Google search for the words '200LX hinge crack'.
There's a mailing list where it's more on topic: HPLX-L!

Well, a very kind soul has informed me that this cable is a quasi
rare item used to connect peripherals to Commodore PET systems, and
apparently that they are worth a bit of money ($50-80).
So, before I just end up giving this thing away to the person
lucky enough to nail me on a "first come, first serve" basis, does
anyone have any ideas on how to make this part available to anyone
who may be interested in it in an at least marginally equitable
fashion (if multiple people are interested)?
If nobody's interested, then I'll just hang onto the thing -- I'm
sure somebody might run into the need for one sometime in the
future. Otherwise, if you want it, just shoot me an e-mail and let
me know -- i'll wait a little while and see how many people are
interested, and we can go from there...
I don't mean to offend anyone by kind of retracting my original
offer -- I just want to give everyone who may be interested in
the part an equal chance at grabbing it irrespective of "luck of
getting to me first". I'm still not looking for a fortune here --
if anyone wants to cover my costs on the cable (I paid $5), that
would be cool, if not, and you're the only person interested,
well, I still wouldn't be adverse to just handing the thing
out.
Kind regards,
Sean

My current setup is:
library A DEC PWD500a running Linux with mirrored 40Gb IDE
drives.
Acts as MP3 store and also rips CDs like there's
no tomorrow!
Wireless network based around a Multia acting as firewall and
access point
iPAQ running Linux with wireless card NFS mounting MP3 files.
Truly portable
MP3 player.
I've been thinking of buying another iPAQ (3130 black and white) as they've
reached EOL and are really cheap. Add one wireless card and keep it
attached to the surround sound system. Then use the other iPAQ as the
remote control (via a web page served from the B&W iPAQ).
Note, there is some non OT content. The Multia is surely more than 10 years
old and as someone pointed out the other day, so's Linux (I've certainly
been using it since early 1992).

I figure I'll try here first...
I'm looking for a case for some SCA-80 SCSI drives I picked up. They
have plastic Sun drive rails, from their RAID tower, P/N 5402568-03...
Those rails are useless to me, and therefore up for sale/trade;
unless of course I can find a Sun box to use them in.
