I have a couple large double-wide 19" equipment cabinets that used to
contain the components for a Nicolet NMR spectrometer. They are six feet
tall and would hold lots of gear. Before I scrap them I wanted to offer
them to anyone who could use them. I would like a token amount (basically
the cost of the steel scrap, which would be maybe $30-$40.
Local pick-up would be required (I really doubt someone would want to ship
these).
If there's any interest let me know ASAP and I'll send photos. I need to
be rid of these within the next few days as they are consuming valuable
space that I need to recover.
Please reply directly to me.
Thanks!

I just took apart a Thinkpad 701c that has a BIOS password that I am
attempting to clear. There is some powdery residue caked inside the battery
compartment that has leaked into a few areas surrounding it. Is there a
safe way to remove this?

I'm trying to get rid of some stuff I'm not using, so if anybody wants
to come and get it... I'm open to deals, trades, and negotiation on
everything.
Sun Ultra 10, 440 Mhz, 256 MB RAM, 9 GB drive. I'd like a little cash
($20?) or booze in exchange for this.
Sun Ultra 1, 175Mhz (?), 64 MB RAM, 9 GB hard drive. Trade for beer?
20" Sun monitor, 13w3. Take it for $5 or I'll throw it in with either
of the Sun boxes
Sun Type 5 keyboard & mouse to go with either of the computers.
DEC Multia, Alpha processor @ 166Mhz, 64 MB of RAM, no hard disk. $10?
and finally
Cisco 7505 router w/ 4 fiber Fast Ethernet ports and FDDI interface. I
have tested it, I know it boots. $75 (I feel the need for compensation
after hauling this around for 2 years)

Fewest parts would be to use a FIFO feeding the "O" back to the "I"
I had thought about building a state sequencer this way once for a project
where the sequence was of programmable length, but didn't require branching.

The ADM3 'A' version differed from the original by replacing the recirculating
shift registers with 2102's and a 10 bit counter.
Hi,
A while ago I got one of these off a friend of a friend and got it going a few
days ago. I was wondering if anyone had any information about it,
specifically a technical reference manual. I'd like to have a closer look at
its architecture, just out of curiocity and for this...
The hard disk interface is a WD33C93 and has a BIOS to let MS-DOS access it.
It currently has its original 20MB Miniscribe hard drive internally and I
attached an external 140MB 5.25" SCSI drive.
Just as an experiment, I attached a CD-ROM drive to it and set the number of
SCSI drives to three. It detected the CD-ROM drive when there was a disk in
it, but MS-DOS doesn't natively support ISO9660 drives. So I made a 20MB hard
disk image in QEMU, partitioned it in FDISK and formatted it, then burnt the
image to a CD. MS-DOS detected it as a drive first go. This shouldn't be a
surprise if you know a thing or two about the SCSI architecture.
This makes me wonder if there's such thing as an ISO9660 extension for MS-DOS
that will let me access CD's in this way. The issue is if I don't have a disc
in the CD-ROM drive when it boots it will fail to detect the drive.
The other option is writing a driver for the WD33C93...
Thanks,
Alexis

No, just until you're about in your mid-30s or so.

A post about a multiprocessor PDP-11/45 made me think about a
multiprocessor microPDP-11/83. Is it possible to connect the Qbus of two
microPDP-11/83s together? what about Unibus PDP-11/84s? The -11/83 is
more interesting, because I can replicate it.
Since bus arbitration is handled by the processor, arbitration on one of
the processors would need to be disabled. The KDJ11-B Users Guide
doesn't suggest a way to do this. The arbitrating processor would also
have to field all the interrupts.
I am tired of reading about the first computer on the internet...
Besides, I have not heard any of you wise guys argue that there couldn't
be a first computer on the internet (or Internet) or any network since a
single computer can't make up a network.

Don't overlook the Dollar stores (or whatever they're called in your
part of the world); that's where I found my tiny torx.
And FWIW, up here N of 49 Active sells a fairly complete 32-pc security
bit set for ~$10.00.
