Virgil Dupras ab6a2688fe recipes/trs80: self-hosting 2020-05-06 12:38:33 -04:00
Virgil Dupras b89fa2981f recipes/trs80: move RECV program to blkfs 2020-05-05 22:21:27 -04:00
Virgil Dupras 31119c2de3 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.

Virgil Dupras f023f9bcb4 Pack core words blks a bit tighter 
With all this recent movements, we had a bit of a fragmentation
issue.

Not worth the complexity and space.

Virgil Dupras 0044011f06 Move AT28 and TRS80 drivers to higher blocknos 
I'm reserving the 100-200 range for non-bootstrapping needs.

Virgil Dupras b046aba7f9 recipes/trs80: running! 
no floppy yet.

Virgil Dupras 6c51ea1ebb recipes/rc2014/selfhost: complete instructions 
I have yet to test the whole process on real hardware. Soon.

Virgil Dupras f690cb2e5b recipes/rc2014/sdcard: use driver from blkfs 
This completes the migration of all Collapse OS code into blkfs!
 2020-04-26 19:50:38 -04:00
Virgil Dupras 865f4f9256 Move AT28 driver to blkfs 
And adjust rc2014/eeprom recipe
 2020-04-26 15:18:28 -04:00
Virgil Dupras 7c692c1111 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.

Virgil Dupras dee7eea497 Move link.fs to blkfs 2020-04-26 14:37:54 -04:00

Virgil Dupras a2f164ecc3 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.

Virgil Dupras 1bd191e86a Move /emul/forth/* to /emul 
Less noisy this way
 2020-04-24 17:53:58 -04:00
Virgil Dupras f19a5e1f71 Remove recipes/rc2014/zasm 
That becomes irrelevant in Forth
 2020-04-24 10:59:28 -04:00
Virgil Dupras 44403c3d4c Move icore to blkfs 
The way is clear for complete stage1 bootstrapping on the RC2014
target!

Virgil Dupras 8fbbf5209a Copy sdc driver to blkfs 2020-04-23 13:55:00 -04:00
Virgil Dupras a19376df6c Copy ACIA driver to blkfs 
We can get rid of acia.z80, but not of acia.fs yet, we still need it.

Virgil Dupras dd6ce1b8fe Avoid using (xentry) outside xcomp config 2020-04-23 12:09:31 -04:00
Virgil Dupras fcd77f80ab Use blk's boot.z80 2020-04-22 21:49:44 -04:00
Virgil Dupras 7a0e63746f parse: don't validate 0x and 0b lengths 
It doesn't serve much purpose and takes up many precious bytes. And,
after all, parsed didn't do it either...

Virgil Dupras bf49ca2ed2 recipes/rc2014: fix Makefile 
It didn't have z80a anymore.

Virgil Dupras 98191d0b0d recipes/rc2014/sdcard: now works under Forth! 2020-04-19 16:56:37 -04:00
Virgil Dupras dfaa1dc101 link: add "offset" argument to RLDICT 
As long as our target was the first word of the "user" dict, using
target's prev to compute offset was fine, but when the target is not
the first word, this system breaks down.

This is the case when, instead of including source code in our boot
binary, we paste it in Collapse OS' prompt.

Also, adjust RC2014 recipe to include stage 3 assembling instructions
with the "paste into prompt" method.

Virgil Dupras a2d89de557 drv/sdc: implement core words in z80 
In addition to making the driver significantly faster, it allows us
to make SDC port configuration opaque to sdc.fs.

Virgil Dupras d0545d555f upload: use A! instead of C! 
It makes the tool much more versatile. I'll have adev being included
in all recipes, so it can be assumed.

Virgil Dupras d08a9711c5 boot: make HERE point to RAMEND instead of CURRENT 
The former was only used in the peculiar context of "/emul". The
regular case is actually HERE pointing to RAMEND on boot.

Virgil Dupras c515720e23 Revert "Remove link.fs" 
Let's revisit the relinking approach, with LITA this time.
This reverts commit 6652125d47.

Virgil Dupras 6368cc3bac Remove (sysv) 
Replace its usages with direct RAM+ offsets. The (sysv) mechanism was
incompatible with cross-compilation of a full interpreter.
