Add a layer of indirection for KEY 2020-05-02 10:37:37 -04:00			`CODE (key)`
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			`A 0x01 LDri, ( @KEY )`
			`0x28 RST,`
trs80: implement AT-XY Also, I've run VE on the TRS-80 for the first time! It doesn't work well though. Screen is mostly blank all the time. I removed instructions from the recipe which became obsolete when Collapse OS became 100% bootstrapped. Also, I've updated instructions to change the NL override which is necessary for blkup to work. 2020-06-07 10:37:00 -04:00			`PUSHA,`

Add layer of indirection to EMIT This would allow things like temporary giving control to the CL line on the TRS-80. For example... A very far fetched example. Not at all the only raison d'etre* of the layer... 2020-05-01 20:05:15 -04:00			`CODE (emit)`
