I have a couple 3c509b ethernet boards for 16-bit ISA busses. Anyone want them? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

BCS at 50

by ljw-cctech＠ljw.me.uk

I've uploaded some photos from the BCS at 50 event at Bletchley Park today. http://www.flickr.com/photos/ljw/sets/72157600782178592/ 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. -- Lawrence Wilkinson lawrence at ljw.me.uk The IBM 360/30 page http://www.ljw.me.uk/ibm360

Useful Information

by Billy.Pettit＠wdc.com

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. Billy

The fet is for high input impedence and the transistor is for increased gain. Other wise know as a reflex receiver. Allison

VCF/MW dinner

by pat＠computer-refuge.org

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.

CP/M for DEC VT-180?

by david＠marmotking.com

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.
