We used to make all of our own cables and sometimes even build our own
computer systems.
We built several using a Heurikon system board, Fujitsu Eagle 400 MB drives,
Kennedy tape drive, wyse terminals, Western Digital 5 1/4 disk drive,
Printronix printer, Hyperchannel network boards and hubs and a Ramtek color
monitor. Cabling was always a nightmare. Cable clamshell covers always got
left off so we could visually inspect the connections.
One hint never solder up 25 pin cable connections after having a beer. My
eye hand coordination slips.
Every device seemed to prefer its own "flavor" of connection. tie 6-8-20
together, crossover 2,3,4,5. Lots of our connections were straight through
with the cross-overs in the connector or gender changer. We usually cut
large holes in the wall, it was easier to plaster a hole than cut off and
reconnect a cable end connector. Of course many just hung down from the
ceiling.
Our tech always carried a breakout box and several gender changers. We also
had a little vacuum based vise to hold the connector while you soldered on
it.

It occurs to me that there are several PDP-8'ers here. Quite some time ago,
at least 1992, I got involved with a group of people, and one of them was
Charley Lasner. As far as reptutation went, he was the guru of -8s. He lived
in NYC at the time, and I visited him for the weekend. Actually, it was the
very same weekend that ST:TNG premired, because I was little disappointed
that I missed it, but I figured hacking was more important!
So, does anyone remember him or know how to reach him?

I picked up several systems from a fellow list member (thanks
Kelly) and I'm looking for any links, info, etc. on them to help me
get them all up and running again. I picked up 3 RCA Cosmac
VIPs (to go with the one I already had, also from Kelly), 3 SWTPCs
with different boards (I have to look through and find out what cards
are there), a Netronics Explorer and on a sort of temporary
permanent loan, a Super Pet. Oh, and a Sun IPC motherboard, at
least we think that's what it was. Not sure which model. I'm
working on cleaning them up, testing power and cataloguing them
before beginning work on restoring the systems. Any info, help,
links, whatever would be appreciated. More info to come soon for
any who are interested.
Thanks.

Hi all, I am gathering the memory offers on the NeXT hardware. If you have
sent me a generic, "what do you want for..." email, please, if you could:
make me an offer. I am comparing the offers made and will be making a
decision Sunday or Monday. The RAM is for computers I am giving to kids who
live in foster care situations, so you can be sure I will be going for best
offers.
RAM type needed: for ppc 6100, 7100, 8100, performa 520/550/575/580, quadra
630/640, centris 610/660 AV, 7200, 7300, 7600, powercomputing powerwave
I have:
1. 3 very clean NeXT boxes (040 25 MhZ)
250 MD hard drive (needs to be reformated and OS loaded)
20 MB RAM
2. 4 MegaPixel NeXT Displays with monitor cable, very clean
3. 14 NeXT keyboards, clean
4. 3 NeXT mouses (will go with boxes if trade includes), clean
5. 3 NeXT 12x external CD DRIVES with cables, very clean
6. 3 NeXT laser printers (these are sharp looking!) with
cables

Hi all
I ran across these two items yesterday and is thinking about purchasing them (one or the other, not both). I have zero knowledge of the DEC systems, but the Vaxlab, I never heard of before.
Can someone give me a little info on these especially the Vaxlab. I would like to know what was it used for and give me a link with some info. Also what price should I pay for this, not knowing if it works or not. The place I am buying it from is known for unrealistic prices, so I did not bother to ask until I know if I need it.

In fact... I seem to remember that the Ultrix-11 installation
manual specified this action during the installation process.
No urban legend.. I remember doing it on a home -11...

A very knowledgeable individual on this list (hi Sridhar!) mentioned
to me once that modernized MCA (faster, 64-bit, etc) was seen in new
machines much more recently than that. Sridhar?

Finally the chip dropped! (Or whatever you say en anglais =)
Or, IOW, my collection finally got somewhat interesting again. In the last
weeks, I have found an ABC-800 (for free at the dump), yet to be tested since
it needs to be supplied with power through the monitor. It seems as though it
could be useful as a terminal, given its ROM and serial ports. Quite nice
keyboard, too.
Today, I was at the fleamarket and found a Japanese word processor with
carrying case. It's a NEC Mini-5 thing. Could actually be useful, providing
the LCD still works. Cost me 40 crowns.
At an additional 40 SEK (a steal!), I found a boxed TI-99/4A. Came with
documentation, PAL modulator, joysticks and "TI invaders". =)
I really like the keyboard, but now I really need a male-male RF cable to plug
it in. =/
I was also alotted an Apple portrait display. I really prefer my Sigma
Pageviews though, they look much nicer.

For many years I used a standard null modem cable to connect my PC's
with my A1000 to transfer software between them, can't get much simpler
than that.
