WHat kind of -11, do you happen to recall? I assume someone will have grabbed the 'Bolics machine... Hyper-desirable. I do hope someone will be able to scoop up all this stuff. Even if all you do it put it up on eBay, that's still better that having it go to scrap! Noel

Model 33 wiring complexity

by tshoppa＠wmata.com

The Model 33's I bought back when I was a teenager, were all ex-Telex use and had exceedingly complicated wiring harnesses as well as built-in modems. They had paper tape readers and punches with various auto-start/auto-stop relay options. The exceedingly complex wiring harnesses were to add various options. The wiring harnesses made the wiring of the unit look, literally, a thousand times more complex than it actually was. In the end all I ever did was find the magnet wire, and the keyboard contact wire, for the main unit and the punch. I usually also found a useful current loop supply in the base. Sometimes I would find bipolar relays and 20mA/60mA conversion supplies. I was a little surprised at some of the current loop supplies - some of them weighed 20 pounds and were obviously made for driving exceedingly long lines (open-circuit voltage way over 100VDC). Seemed odd these were in there considering the units had modems just a foot away from magnet and keyboard switch. Tim N3QE

Locust 1-2-3

by lproven＠gmail.com

This came up recently due to a small coincidence. Does anyone remember this early MS-DOS game for PC compatibles? It was designed to look exactly like the spreadsheet, so you could play in the office, but you had to "shoot" falling numbers by doing arithmetic... It looked just like a mockup of 1-2-3 r2.01, the classic version. >From very vague memory... There was an answer line at the bottom. Numbers would trickle down the current column. You had to add, subtract, multiply or divide and input the correct answer. If you didn't, your mistakes piled up, like incomplete lines in Tetris, giving you less room and so less time to do the computation, until you died. Then a new column began, I think. When all the columns were full of figures, you'd died and had to start a new game. It wasn't much of a game, but it was kinda fun, and it was a perfect mockup of the spreadsheet, so it would pass casual over-the-shoulder inspection. -- Liam Proven ?

Need help reproducing a PCB

by brain＠jbrain.com

I am trying to reproduce a PCB design, and I have removed all the ICs, scanned the boards, and am trying to draw it up in EAGLE. But, it would much easier if I could import the actual PCB as a bitmap under my PCB layout, to ensure I have have everything in the right place. Sadly, my graphics manipulation skills are suboptimal, and I am wondering if there is anyone on the list that could take my scans and convert them into 2 color bitmaps of the correct size such that I could import. When I tried to convert, the difference between light green and dark green essentially removed most of the traces. Jim -- Jim Brain brain at jbrain.com www.jbrain.com
