Add a layer of indirection for KEY 2020-05-02 10:37:37 -04:00			`CODE (key)`

			`0x28 RSTn,`
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)`
