I am putting together an exhibit to show at the Train and Hobby Show next month (details in a reply).
My theme is Snow White design language Apple computers.
I'll be exhibiting three Apple computers, an Apple IIc, Mac SE and a Mac II. I own the IIc and SE, and borrowed the Mac II from a friend.
We didn't know if this Mac II worked, as it was in a huge job lot. Out of the two Mac IIs they have, this was the cleanest.
To get these to power up, both batteries should be fully charged. You can also jump a 3.6v battery. I gave it a clean, checked for RIFAs and jumped it.
And it works! First time, correct chime

Someone asked me in the pull request comments how I'd generated thousands of test cases for #DesmetC, and I figured the #retrocomputing heads here in the fediverse might be interested in the answer, so I'm linking it here too: https://github.com/the-grue/OpenDC/pull/9#issuecomment-3866218702

I didn't put a lot of thought into the approach, and I'm sure it could be made much more elegant, but damn if it didn't flush out a lot of bugs.

Fix and regression-test integer arithmetic and comparison by PeterFidelman · Pull Request #9 · the-grue/OpenDC

Math operations now promote to int, unsigned, or long, in the C89 standards-compliant way ("usual arithmetic conversions"). Most notably, this removes the DeSmet-ism by which char additi...

My favourite terminal emulator to dial BBSs was cracked Telix for DOS.

You can still use it today because we added a backend where telephone numbers can be mapped to internet addresses to @DOSBox_Staging.

Hello from #snac , running on an old Pentium 3 900 MHz system with 512MB of RAM and 40GB 5400RPM HDD with #OpenBSD as operating system

This is very slow. And that's not caused by the old CPU. Hopefully a new ssd + ide>sata adapter will arrive soon.
