Virgil Dupras	b21be43535	Move 8086 assembler from B730 to B30 ... Also, move doc to doc/asm.txt. Also, fix the pcat recipe which was broken since the overlay change. I hadn't noticed it because I didn't have to rebuild the MBR.	2020-09-21 19:24:54 -04:00
Virgil Dupras	b1a95648f1	De-stabilize EXIT ... This marks the end of wordrefs in stable ABI. Nice.	2020-09-19 20:35:35 -04:00
Virgil Dupras	e4a4a9800d	z80: Use BC as IP register instead of IY ... It's a bit more inconvenient in terms of register protection (BC is much more generally useful than IY), but it makes tight spots such as next and execute much faster, so I think it's worth it.	2020-07-06 23:31:00 -04:00
Virgil Dupras	5a2612a9c5	Add HERESTART xcomp config	2020-06-28 19:45:28 -04:00
Virgil Dupras	3068b58be5	Rename RAMSTART to SYSVARS ... It's more descriptive this way. Also, I'll soon add a new HERESTART config.	2020-06-28 18:49:30 -04:00
Virgil Dupras	da371451cc	Replace INITIAL_SP with PS_ADDR conf ... Now I struggle to remember why I ever did things they way I did. There must have been a reason...	2020-05-11 21:08:24 -04:00
