Yak-shaving at its finest!
I want to build a 68K-based machine. To avoid needing too many TTL chips, I wanted to use GALs. I played with GALs, and eventually got them working, but not before looking at the source to galasm and deciding that it was a bit old and crufty and I didn't really trust that I understood its corner cases.
So, I wrote Galette, a largely-galasm-compatible GAL assembler, written in Rust and hopefully a bit more maintainable. Yaks-shave completed.
