Can anyone identify what this board is/does?

by tony.aiuto＠gmail.com

https://www.ebay.com/itm/263005049078 EBay listing for a "Soviet Magnetic Ferrite Core Memory Board". It looks like 20 something gigantic cores and a lot of diodes. I am guessing it is some kind of ROM, but it doesn't look like a rope memory. And maybe the cores are not cores at all, but some sort of inductor. I've not seen this before.

SOL-20 and Helios-II in Louisville

by brian＠marstella.net

Hope this isn't too far off topic, but noticed a SOL-20, Helios-II, and several disks available in Louisville via Craigslist. Can't afford more stuff this year myself but price doesn't seem too bad. i don't know the person that has it, just found it as I was searching. https://louisville.craigslist.org/sys/d/processor-technology-sol-20/6391107… Regards, Brian.

I've been using it to burst those TIFs into individual pages before making PDFs out of them. I'll post a link to them when they're ready. J

TRS80 Model 1 video RAM (2102A)

by binarydinosaurs＠gmail.com

Hi folks, After sorting out the Model 4P (thanks to all who provided hints!) and scrubbing it up so it almost looks new again I turned attention to my Model 1 Level II which had been dead for at least the same amount of time as the Model 4. There?s some excellent troubleshooting tips for these machines out there and I quickly discovered a bad RAM chip, swap that for a NOS one and we?d be back in business if the video RAM wasn?t failing. One of the 4 2102A chips is failing (MEM SIZE becomes OEO SIZE) and I?d like to double check this before I stump up the ukp4 required for a pair of NOS ones, can anyone think of a machine from back then that also used 2102A or 2102LPFC or NTE2102 video RAM? Cheers! ? Adrian/Witchy Binary Dinosaurs - Celebrating Computing History from 1972 onwards

PTAP2DXF - make paper tapes without a punch

by steven＠malikoff.com

If you have a paper tape reader and no punch, you can now make real working paper tapes using a normal home stencil-cutting machine. I've written a small command line utility that can take a .PTAP (or any other binary or textfile) and generate output that these machines will cut. that your reader will read. It can easily make repair pieces for existing old broken tapes from any byte offset. In addition it can make banner tapes, 5-level Baudot RTTY tape, your own custom n-level paper tape or cut tapes from other materials such as plastic. Even if you don't need it to make or repair tapes, it can be used to visualise a paper tape through the console output it produces. I'd never claim it's any sort of replacement for a real punch, and it's a whole lot slower. But, it does work :) A simple example to make a tape of the characters ABCDEF with 1/2 inch of sprocket leader and 1/2 inch of trailer: C:\> ptap2dxf --text="ABCDEF" --leader=5 --trailer=5 --output=ABCDEF.dxf +---------+ | . | | . | | . | | . | | . | | O . O| | O . O | | O . OO| | O .O | | O .O O| | O .OO | | . | | . | | . | | . | | . | +---------+ Joiner 0000: data byte 00000000 absolute position 00000011 The resulting ABCDEF.dxf file can be viewed in a DXF viewer such as Inkscape and directly loaded into the paper/vinyl cutter for producing the actual working tape. Another example: say you need a repair piece for an absolute loader, starting at byte 57 for 12 bytes. (A repair piece has removeable side tabs for handling as a self-adhesive vinyl joiner): C:\> ptap2dxf DEC-11-L2PC-PO.ptap --range=57,12 --joiner --ascii --control +---------+ | O .O O| JOINER % | . O | JOINER <STX> | . | JOINER <NUL> | O . O| JOINER ! | . OO| JOINER <ETX> |OOOO .OOO| JOINER | O. O| JOINER <HT> | O O.O | JOINER , | . | JOINER <NUL> |O .O | JOINER | OO . OO| JOINER c | . O| JOINER <SOH> +---------+ The output for machine cutting will be in DEC-11-L2PC-PO.dxf For larger tapes, the output can be chunked into sections which can be cut individually. There are other options to invert, mirror, reposition the sprocket feed and so on. If you think you may find it useful, it's fully open source and available at https://github.com/1944GPW/ptap2dxf It will run on Windows (pre-built exe provided) and Linux and Mac (follow building instructions).
