And the optimizer is really only a backend optimizer. The size reduction also helps with JIT candidates which have a default max size of 96 bytes (chosen somewhat empirically through a bunch of tests). The additional byte codes in PLASMA 2.0 were specifically targeted to help with common code sequences and FOR/NEXT loops. There are a few more I wanted to add, but the JIT compiler for the existing byte codes is right at 8K - my self imposed limit on JITC size. Always tradeoffs.

Thanks - I have to really clean up that image.

Looks like it's in bank 0 - $2000 and $4000 for even/odd and the nibbles interleaved? Can you shed some light on how that video mode works?

So it's pretty much the 560x192 mode but interpreted as 4BPP, 16 shades of grey or color (depending on what's hooked up to the video ports). Just like Double HiREs on the //e and //c.  Due to the way the Apple /// maps screen memory, it's very difficult to read and write directly to the screen. You need a helper, this is where the device driver comes in - but it's a slow API. Someday I'll get the HGRLIB ported to the Apple ///.
