http://www.retrotechnology.com/herbs_stuff/clean_disks.html There's any number of Web pages about dirt and cleaning dirt on magnetic media. My site has collected what I think are reasonable practices. I've not discussed 3D printed "disk cleaning frames" as they did not exist until recent years; I'll add that information.

Museum Report: 12 August 2020
by svcatitc＠aol.com 15 Aug '20

15 Aug '20

Opened museum 1p. It is a bit ironic considering the deluge of "carwash" rain we got today that we had as many visitors as we did. Busy day. Four (4) groups of 3-4 people came in, (2 groupswere families) starting around 2p. Just a mild interest in the technology, however it was theparents that listened with intent. The last visitor was a repeat customer, an older gent withexperience on electronic cash register and associated equipment, working forNCR. Closed at 5p Bill Inderrieden

Needed 5-1/4? Cleaning Floppy
by David K 14 Aug '20

14 Aug '20

I recently bought a 5 1/4 version of Witness from infocom. I bought it for the contents as the listing said the disk was bad. Visually looking at the disk it looked dirty. I used a sharp hobby knife to open the disk "envelope" at the top edge (the edge you hold when you put the disk in the drive). This allowed me to totally remove the magnetic disc itself - being careful not to touch the magnetic parts. I used 90% rubbing alcohol and a cotton ball. I cleaned the bottom side of this disk because that was the side actually read by the head. I used moderate pressure and cleaned the disc in a circular pattern from outside to inside. I could see some dirt on the cotton ball. I let it dry completely and then put it back in the "envelope" and tried it in the drive. Initially it did not work but after repeating the same process two more times the disk has been working. I have used this same process with other "dirty" disks and been successful maybe 30% of the time. David K

Zip 100 drive cartridges
by Sentrytv 14 Aug '20

14 Aug '20

I just found an old 486 computer and it has an IDE zip 100 drive. If anyone who going to the workshop (or museum) and can bring a couple of those cartridges I would appreciate it. I want to back up the hard drive and the only way I can think of to do it right now is on that zip drive if it works. I won’t be at the workshop, but I could stop by if anybody has them, just let me know. I’m going to see Alex J. sometime late afternoon. Thanks Mike R.

Keyboard encoder chips?
by Richard Cini 14 Aug '20

14 Aug '20

All – I was recovering an ASCII keyboard from a video titling machine (no documents) and in it is a Clare/Pendar keyboard that’s in nice condition (#700223-K1-1). The gold-pinned ceramic encoder chip on it looks like a General Instruments “S0778”. The only other numbers/markings are “GI 3-24-70”. I have seen references to a “S077D” used in the Apple keyboard, but I have no data sheet on that. The other reference I thought might be “AY-3-2470” but no luck there either. Of course, either could be a date code, too. I have several GI data books (1977, 1980 and 1982, which would be the right timeframe for this keyboard) and the GI keyboard encoders were AY-5-2376 and AY-5-3600. Any clues would be appreciated. Thanks! Rich -- Rich Cini http://www.classiccmp.org/cini http://www.classiccmp.org/altair32
