Move icore to blkfs The way is clear for complete stage1 bootstrapping on the RC2014 target! 2020-04-23 15:14:14 -04:00			`0xe800 CONSTANT RAMSTART`

Use blk's boot.z80 2020-04-22 21:49:44 -04:00			`262 LOAD ( xcomp )`

Avoid using (xentry) outside xcomp config 2020-04-23 12:09:31 -04:00			`: (entry) (xentry) ;`

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 08:23:53 -04:00			`CURRENT @ XCURRENT !`
Add CURRENT* and simplify xcomp 2020-04-09 12:01:08 -04:00

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 09:55:58 -04:00			`H@ XOFF !`
