Remove INTJUMP mechanism Not worth the trouble. Easier to set jump in binary directly. 2020-05-14 15:13:16 -04:00			`(entry) ~ACIA ( Set RST 38 jump ) PC ORG @ 0x39 + !`
z80a: make mnemonic names more uniform across assemblers Initially, I used the same letters as those used in the z80 ref docs, but it makes the different assemblers harder to use than they should. Having consistent "argtype" rules across assemblers should help. 2020-06-27 22:01:56 -04:00			`AF PUSH, HL PUSH, DE PUSH,`
Copy ACIA driver to blkfs We can get rid of acia.z80, but not of acia.fs yet, we still need it. 2020-04-23 12:42:41 -04:00			`( Read our character from ACIA into our BUFIDX )`

rc2014: add a declaration part to ACIA drivers Driver configuration don't need their own words at runtime, we only need to compile them as literals when compiling words. Now that we have this "declaration blocks" pattern emerging, it seems like a good idea to take advantage of this in drivers, both for simplifying the xcomp unit and to make final binary slimmer. 2020-06-28 17:30:01 -04:00			`ACIAW> LDHL(n),`
