The oldest Unix written in C was successfully recovered from tape this weekend -- and here it is running on IRIX.
The amazing bit is the contents of the big window in the middle, for children under 50, *not* the windows themselves.

For better or worse, this is my #wrapstodon2025
Apparently y'all schadenfreude loving #retrocomputing people really enjoyed the time I destroyed a DVD drive 😸
I'll do my best to destroy more hardware in 2026 for your amusement.

A friend of my sister's needed a new laptop, but she has no money. So I went diving at the municipal dump, found an i3-5005U based laptop. Threw in 8GB of RAM that I literally pulled out of the trash, and a 128GB SATA SSD.
