I visited JJ's shop (https://obsoletetech.us) yesterday to fill some gaps before my demo this week.

He graciously let me borrow his Magnavox CM8562 monitor from his personal collection, so I can still demo my CoCo3, as my new Tandy CM-8 is having signal issues I haven't fully diagnosed. I also got a working Commodore 1541-II floppy drive to replace my broken 1541 and a cassette recorder to use instead of my CCR-82.

I intended to just get some floppy disk holders for my floppies, but walked out with a lot of floppies too! Lots of colorful ones, some with dinosaurs, 10x of LDS Personal Ancestry File 2.3 for MS-DOS, two Commodore diagnostics disks, and several with interesting-sounding software. I also got two magneto-optical discs with data, which will be nice tests for my recovery setup, and four Zip disks.

The mouse will be a nice fit with my Macintosh SE. I don't know what games use the Commodore paddles, but now I have them.

I just re-inked a ribbon for my Marxwriter, but it doesn't print evenly 😭.

I repurposed a miscellaneous ribbon, removed it from the original spools, and re-inked it with a sponge soaked in stamp ink, while re-winding it in the Marxwriter's spools. Perhaps I'll try again later, but for now this is good enough.

It was shipped with the most inventive packaging I've seen, wrapped in brand new, sliced pool noodles:

My period-accurate Tandy Color Computer 3 setup now has a Tandy CM-8 RGB Color Monitor!

This model was designed specifically for the CoCo3, utilizing its higher quality RGB signal and is the perfect pair for a complete Tandy setup. However, even back in the day, other monitors were preferred over it, such as the Magnavox 8CM515 and Commodore 1084, for their sharper picture and additional input signals. But, what's a retro setup without the quirks of the day?

I'm ready to recover magneto-optical discs! These were kindly donated, to enable us to recover some UNIX-related MO media at the University of Utah.

I'll be giving a talk at VCF PNW!

"UNIX V4: History and Recovery"

software is a mirror that reflects the times and the environment it was created in.

this is why much software created in the 1970s counterculture was joyful and humanistic, and why much software created in the 2020s capitalistic hellscape is soul-crushing malware (adware, spyware).

#retrocomputing can mean celebrating hardware limitations and creative coding, but it can also mean celebrating personal computing - computers that are tools for liberation - bicycles for the mind, not cattle trains to the slop farm.
