I didn't expect to have an earthquake hit in the middle of my video, but we had one here on Japan on January 1st. I talk a little about my channel content, popular videos of 2023, and what I'm thinking about in 2024. (Quake epicenter was the Noto Peninsula in Japan, 205 miles from my area. Our area in Aichi prefecture sustained no damage.)
Check out the YouTube channel of Thomas Andrews @AmigaofRochester
(He's recapping my backlit Macintosh Portable 5126.)
Michael Mullett who sold me the Portable is also selling of part of his vintage Mac collection because of financial hardship. You can find his recapped Color Classic MYSTIC and CD-ROM drive sale on TinkerDifferent here: tinkerdifferent.com/threads/mystic-color-classic-cd-rom-drive-us-1-000.3176
