Hello,
A little while ago I bought a "new" 10ft MMJ cable from That Website.
Today I came to use it and discovered it was a crossover cable. So, my
question is where can I buy a straight MMJ - MMJ? 10ft would be fine,
longer perhaps better, and ideally a UK source.
Whilst on the subject of DEC, I'm also looking for an ethernet card for a
PDP 11/53 and perhaps a TK drive (assuming that if on power-up the drive
wheel just spins continually and you can't lift the handle, the drive is
broken).
Cheers,
Andrew

a at smokebelch.org
is it likely I'd be able to read disks from this system on one of the following (all equipped w/8" floppy drives):
IBM System 23/Datamaster
Canon AS-100
NEC APC
Subject says it all :
I need to replace the floppy drive in my Lilith.
The floppy PCB is so crappy that further repairs are pointless,
PCB traces fall off whenever a soldering iron comes with smelling distance.
Willing to pay reasonable amount, location Switzerland

Spotted on ebay...
DEC H-500 computer logic trainers.
I thiink it is a reasonable price and there is the chance to make an
offer. Front panels look PDP-8 vintage.

No connection with the seller, just spotted what I hope is an interesting item.

A new version of my Wang 2200 emulator, version 2.1, was just released after a three year
snooze:
http://www.wang2200.org/emu.html
This version runs on Win XP/Vista, PPC OS X, or i386 OS X. Full source code is included.
The big changes are support for large format disk geometries due to emulation of the
intelligent disk controller protocol, 2200B mode, the ability to print directly to the
parallel port, and a massive code clean up.

Hi everyone
As a 4th year computer engineering student with a part time job, I
definitely have too much time on my hands, so I've been thinking about
doing something like building my own computer. I remember playing with
the 68k SBCs back in my assembly class, so I thought something from
that family might be an interesting choice. It's ambitious, but
ideally I'd like to do 16/32 bits and a few megs of memory.
Have any of you built something like this? I'm looking for links to
project pages, shared experiences, and advice on what processor to
use. Reminiscence is welcome too, if you have fond memories of such a
thing :)
Thanks
John Floren

Hi! If you are interested in home brew computing you are welcome to join us
on the N8VEM home brew computer project. It is currently Z80 CP/M based but
if you would like to explore 6800/6809/68k designs you could design your own
SBC and reuse the peripheral board designs we have already.
There is an SBC, an ECB backplane, an ECB bus monitor, and an ECB
prototyping board available now.
There have been 68k based ECB designs in the past although I am not an
expert in how those work. As long as it uses +5, GND, Address, Data, and a
variety of control bus signals it should work though.
A Disk IO board (IDE and NEC765A FDC) and a Terminal Replacement Board (uses
VGA monitor & PS/2 keyboard) are in the works.
Several builders have projects as well such as a USB & network peripheral
(!) which allows running CP/NET.
There is another builder with a project that allows wireless serial
communications and numerous interfaces to relays, etc. That same builder
made an AT keyboard interface and a 20x4 LCD display with NVRAM controller.
In short, you could focus on your 68k SBC design while leveraging the
peripherals and standard bus components already available.
Take it for what it's worth. You can contact me offline if you'd like more
information. There are photos, schematics, PCB layouts, ROM images, parts
lists, BOMs, and bunch of other stuff on the website. The PCBs are all $20
each. Good luck with your project!
Thanks and have a nice day!

The Alameda County Computer Resource Center (ACCRC) is forced to liquidate
its computer museum due to the current economic climate. The VCF has been
contracted to auction off the ACCRC museum to raise needed funds for their
non-profit operation.
I have put up the first batch of machines at the following URL:
http://www.vintage.org/special/2008/accrc/
In order to use the system you must have a VCF Community ID. Getting one
is simple: just following the links and prompts when you visit the site
above and read the instructions.
I have been cataloging the hundreds of items in the ACCRC museum and will
be putting up auction lots weekly until the collection is dissipated.
There are still many items to go (with lots of duplicates) so check back
every week to see the latest batch.
All items are offered as-is. Functional condition is unknown unless
specified in the item description. For more information about a
particular item, please contact the VCF and your inquiry will be answered
as soon as possible.
Winning bidders will be notified at the close of the auction (see below
for closing time). In the event of a tie bid, the winning bid will be the
one submitted the earliest. Upon receiving a winning bid notification,
payment and pick-up at the ACCRC facilities in Berkeley, California, is
preferred. Payment from winning bidders is due within 72 hours after the
close of the auction. Non-payment will invalidate your high bid and the
item will automatically go to the next highest bidder (no exceptions).
Upon request, items will be packaged and shipped at bidder's expense plus
a $25 handling fee. Payment in the form of cash, money order, or PayPal
(in that order) is preferred. Personal checks will be accepted on the
condition that they first clear the bank.
All items must be sold. No reasonable offer will be refused. Your
purchases will go towards supporting an organization that over the years
has provided nearly 20,000 refurbished computers to needy organizations
and individuals worldwide. 100% of the proceeds of this auction will go
directly to the ACCRC (minus the handling fees, which are covering my
time...barely).
Please contact me DIRECTLY with any questions you might have of any of the
items. I'll be happy to get more notes and photos on particulars items of
interest from inquiring bidders.

Subject: RE: USB Model M
I think this is not the classic IBM keyboard we're talking about. *The*
classic keyboard has the part number 139140x where x differs from country
to country.
This is what's on the label of my keyboard (a rather new one, the oldest
one I have dates from 1987 and came along with my 8550-021). There's no
IBM logo on the bottom, only the oval grey logo on the top left.

PS:
The US version of the keyboard is the model 1391401.
-------------Reply:
Probably no point in arguing with someone who, because his
particular keyboard does not say "Model M," therefore insists
that "IBM *never* called the (Model M) keyboard a Model M."
Presumably even if I sent him a picture of one of my 1391401s
plainly labelled "Model M" he would not be convinced any more
than he is by others on here and the extensive Wiki entry.
Oh well...
Here's another batch of things that I don't have time to play with. Same
deal as before -- tell me you can come and collect them from Crawley,
the sooner the better. Most of these are easily obtainable, so they will
go to landfill if they aren't claimed.
Sharp MZ-700
2 x Amstrad CPC 464, one boxed and clean, the other with the inevitable
cracked cassette cover
DEC Letterwriter 100
DECserver 200/MC (DSRVB-A)
2 x Commodore Amiga 500
Acorn Electron and games
TI Silent 700 (the enormous briefcase one with acoustic coupler)
2 x DEC TK50Z drives
2 x Commodore 64
Motorola EXORterm 155 -- no keyboard with this.
AVID video editing unit and the BBC micro that it was used with
I've put photos of some of these on Flickr:
