Virgil Dupras	650481f849	z80/8086: extract 2>R code from stable ABI zone ... Only its jump at 0x33 remains. I've also fixed a strange offset oddity in 8086's (n) placement. It was off by 2, but strangely, it ran properly. Anyway, now it's fixed.	2020-07-05 08:03:15 -04:00

Virgil Dupras	6bc1738bfd	pcat: implement (loop) ... 8086 asm is a lot terser than z80... Those indirect memory operations are very handy.	2020-06-18 15:01:04 -04:00

Virgil Dupras	d8d2e05eb2	pcat: make find compare strings ... find is the biggest chunk of logic of the boot code. The 8086 version is significantly terser than the z80 one. REP/CMPS helps...	2020-06-15 06:23:19 -04:00
Virgil Dupras	8c452f5add	pcat: begin implementing find ... Not comparing strings yet. Without asm tooling support, it's a big chunk to swallow at once. It's progressing well!	2020-06-14 21:52:58 -04:00
