Dear Alex, Top of the morning to you!

I only had a quick look at the codebase. A lot has changed! :) Alcor6L has a mode called 'optram' (RAM optimization) which currently doesn't optimize anything for PicoLisp. One can save some RAM by changing platform configuration files and tweaking the build. This is what I used to get PicoLisp to do some crunching in 64K. The next activity for me is to get the miniCodeROM feature to compile (along with gen3m) when `optram' is set to 1 (which includes with it few disadvantages you mention in your wiki + a slight hit on performance I assume since everything is now placed in the flash). Also, currently there are many internal (MCU peripheral specific, immutable) PicoLisp symbols like *tmr-sys-timer* in Alcor6L which have to be listed in init.s. It's certainly some work. Thanks Alex, I'll post again once I've included the changes for the RAM optimization mode.
