California, Ireland, Colorado.
MS Math/CompSci UCLA.
Locus, Sun Microsystems; PDP-11, x86, C, Go.
Programming since 1973.
I wrote the program that calculated the GPA that appears on my high-school transcript.
Starting in 1984 I led the project at Locus to create the first x86 virtual machine, to run MS-DOS under Unix, on the AT&T 6300 Plus (https://en.wikipedia.org/wiki/6300_Plus).

Congratulations!
If you're serious about running Unix, I'd suggest trying to scrounge up the full 256KB of main memory. Back in 1979-1982 I ran the UCLA Math Department PDP-11. The Unix v6 kernel by itself was around 48KB; v7 was around 64KB with just a very few kernel buffers. You might be able to get it to run with 128KB, but remember userspace programs had to swap, not page, so the entire process has to fit resident in main memory to run.
Yes, I remember watching the B machine swap off the DECtape one day after its RK05 drive died. Slow as hell, but it worked -- back and forth and back and forth.
Hell of a story from Julie Brown and The Miami Herald showing lots of suspicious document shredding at the prison where Epstein died in the days after.
