Virgil Dupras d041b91846 Optimize chkPS 
Use EXX instead of the stack for HL protection and remove all
spurious uses of chkPS,

I wanted to inline chkPS in next because of its "tight loop" status,
but for reasons I don't understand, doing so breaks Collapse OS.
Later...

Virgil Dupras 6bff03a48b Move adev to core 
It's small enough to be worth it.

Virgil Dupras b5683f447b sms/kbd: update instructions for Forth Collapse OS 
The keyboard is a bit glitchy, but these are the same glitch as those
that were already present in Z80 Collapse OS. They still need fixing...

Addressed devices are not included in Collapse OS by default. Let's
just accept that upload only works with memory.

Virgil Dupras 7a41c5c6f9 avra: add IF, .. THEN, 
I decided to keep SKIP, .. TO, (renamed from AT,) around and limit
IF, .. THEN, to the simple BRNE case.
 2020-05-19 10:26:57 -04:00
Virgil Dupras 8bbd29d37d avra: add SKIP, .. AT, 
Will change to IF, .. THEN, but I need a way to easily reverse a
BR op. But from this commit, the translation of sms/kbd/ps2ctl.asm
is complete! perfect binary match!
