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`

Replace INITIAL_SP with PS_ADDR conf Now I struggle to remember why I ever did things they way I did. There must have been a reason... 2020-05-12 11:08:24 +10:00			`0xfffa CONSTANT PS_ADDR`

Use blk's boot.z80 2020-04-23 11:49:44 +10:00			`262 LOAD ( xcomp )`

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

Split icore in 2 parts The goal is to insert device drivers in between. 2020-05-09 11:47:03 +10:00			`393 LOAD ( icore low )`

Update z80c.bin's LATEST during xcomp instead of using slatest 2020-04-26 12:02:44 +10:00			`( Update LATEST )`
xcomp: remove XOFF and use ORG and BIN( instead 2020-04-28 23:15:17 +10:00			`PC ORG @ 8 + !`
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 ! "`
Pack core words blks a bit tighter With all this recent movements, we had a bit of a fragmentation issue. 2020-05-03 11:47:32 +10:00			`422 459 XPACKR`

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!`
