ti84: tidy up driver code Pushed all words directly interfacing with ports and memory offsets to low level layers. This saves us the need for keeping those variables in runtime memory. 2020-05-09 22:50:55 +10:00			`( Required config: LCD_MEM )`

ti84: wip Gave more priority to CPU in the emulator because initialization would otherwise be horrendously slow. 2020-05-08 21:56:34 +10:00			`: FNTW 3 ; : FNTH 5 ;`

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. 2020-06-28 12:01:56 +10:00			`0x10 ( CMD ) INAi,`
