I have a couple 3c509b ethernet boards for 16-bit ISA busses. Anyone want
them?

I've uploaded some photos from the BCS at 50 event at Bletchley Park today.

It was a good day with interesting talks from Tony Sale, John Pether and
John Harper. We got to see both the completed Colossus rebuild and the
completed Bombe rebuild operating.
Friday and Saturday the event continues in London.

Al recently posted a useful manual for collectors. It is called the Fujitsu
Sales Prospector 1986. I say useful because it contains a summary of all
the industry's storage peripheral products available in 1986. Basic specs
and some detailed specs on units. So, for example, if you need to know the
differences between different Rodime hard drive models, that data should be
there.
At the end are several Fujitsu data sheets, on 5.25" and 8" hard drives and
the 243X tape units.
A handy manual for high level data on the state of the industry at that
time.

Hi all,
I'm looking for the switch settings and/or a service manual to indicate what
the switches on the back of my 5251 do. Anyone have this data?
Thanks

That is a simple DC coupled amp that is used to first amplify RF then
the detected audio is passed through again. The fet is for high input
impedence and the transistor is for increased gain. Other wise know as
a reflex receiver.

There's just a few more days left until this year's Vintage Computer
Festival / Midwest. So, come and see all of our excellent exhibits put
on by computer collector hobbyists, listen to our speakers talking
about vintage computer topics, and relish in the nostalgia by
buying/selling/trading your own old computer gear at the VCF
Marketplace at the event!
VCF/Midwest 3.0 will be July 14-15, at Purdue University's Stewart
center. Speakers will run from 11a to 2p each day, and exhibits and
the marketplace will be open from 2p to 6p. Admission is $5 per day
for access to the whole event, and kids 17 and under get in for free.
For more details, and to sign up as a last-minute exhbitor or vendor,
please see the official VCF/Midwest 3.0 website at:
http://www.vintage.org/2007/midwest/index.php
If you have any questions, feel free to send me a message at:
vcfmw at computer-refuge.org.
This year's VCF/Midwest is being sponsored by the Rosen Center for
Advanced Computing at Purdue University - http://www.rcac.purdue.edu

Anyone who's coming to VCF/Midwest and wants to meet up for dinner on
Saturday, drop me a message tonight or early tomorrow. I want to get
an estimate of how many people we're going to have, so I can
potentially make a reservation. So, if you'd be bringing someone with
you, let me know that as well.
Thanks,
Pat

I stumbled across a very old post you made asking for CP/M disks for a VT-180. Did you ever find them? I know this is a REAL shot in the dark. I can't seem to locate them anywhere. I was able to find all the pieces to upgrade a VT-100 to a VT-180.
