General discussion of wire wrapping, was: AWG 30 stripping tools

by roger.holmes＠microspot.co.uk

I've got 3 different size wire wrapping tools. My ICT1301 uses monster wire wrap posts, most of which are made in two halves. One half is part of a printed (or some are hand wired) circuit board and the other half is part of the rack it fits in. Bare 25 AWG tinned copper wire is wrapped around the two halves, up to 25 for each board to connect the board to the rack. No tails going off anywhere else. To swap a board all the wire wraps need to be undone before the board can be slid out. It does … [View More]

Semi-OT -- IEEE 802 Committee anniversary

by evan＠snarc.net

I don't normally like to mix work with pleasure, but (selfish plug) here is an article I wrote today: http://tinyurl.com/ykpd6bn It's about the history of the IEEE LAN/MAN Standards Committe -- from which we all got standardized Ethernet, WiFi, Bluetooth, etc*. *< no shame > Slashdotting strongly encouraged. < / no shame >* *

Xerox 820-II floppy images added to bitsavers

by richardlynch3＠tx.rr.com

For those with Xerox 820-II systems, Al has kindly posted a file on bitsavers containing images of a large collection of 8" floppies primarily for the 820-II (there are a few for other systems too) that I acquired a few years ago and just finished archiving this week. There is also an excel file with details on each floppy. These came from someone who worked as a software developer in the late 70s/early 80s and many appear to contain source code. Richard

>which anyone could then program to emulate any disk/controller they like. Ah, well, this is the hard part of the job, right? Building the board is the easy part. I'd buy a couple, at least, without exaggeration, if the Verilog or VHDL to make them functional already existed. Bob Armstrong
