emul: bootstrap to stage2 from within Collapse OS! Big bootstrapping change which greatly reduces the role of the modern operating system in the bootstrapping process. 2020-04-27 00:15:35 +10:00			`( Update LATEST )`

recipes/rc2014: include readln directly in stage 1 XPACK is more efficient than stripfc was, we can pack more stuff in 8K. We now have enough space to fit readln. 2020-04-27 04:52:55 +10:00			`," : _ ACIA$ RDLN$ (ok) ; _ "`
xcomp: move all offset spitting to the end of the unit I'd like to move this code, along with all recipe contents, to blk/. It's easier if "emul-related" code is gathered at the same place. 2020-05-06 10:10:04 +10:00			`ORG @ 256 /MOD 2 PC! 2 PC!`
