Osborne 1 restoration day 5 (non consecutive): Have it flipped upside down so I could pin out the motherboard while connected to the power supply. It now passes the RAM test and boots to CP/M. Woot!

Morning before the work week starts shenanigans: Have you ever had a dumb idea for a project, and you want to get it out of your head, only for it to come out in a rush and work the first time? Weird but... simple RSA (12ish Bit) on a Commodore 64 in BASIC:

With a cheap Starlink mini and a standard drill battery, and I can literally work from anywhere. I bought this during Helene (I live in the Asheville area) and it has become a standard part of my equipment setup. Almost flawless.

My go-to "this meeting should have been an email" is this game. The @8BitDo controller works great on a Mac with the Redream emulator.

A random find in my basement: Unopened Windows 3. It's still wrapped in plastic. Does this mean there's 1992 air inside?

Been using Lua lately because of my Neovim setup and with PICO-8. Then, had an ADHD moment and made a ridiculous speed comparison instead of doing actual work.
