Move icore to blkfs The way is clear for complete stage1 bootstrapping on the RC2014 target! 2020-04-24 05:14:14 +10:00			`0xe800 CONSTANT RAMSTART`

Add xcomp unit for cross compilation Memory mapping is a dead end too, solution has to be at a higher level. xcomp is my new approach. 2020-04-09 22:23:53 +10:00			`CURRENT @ XCURRENT !`
Add CURRENT* and simplify xcomp 2020-04-10 02:01:08 +10:00

emul: build boot binary in one pass ... instead of building boot.fs, and then z80c.fs/icore.fs in separate passes. This strengten xcomp by making it support 2 completely separate dicts (that is, the X dict is not connected to the system dict. The chain now stops at EXIT def in boot.fs). 2020-04-10 23:55:58 +10:00			`H@ XOFF !`

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			`," CURRENT @ HERE ! "`
