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 7464c67c80 boot: fix (roll)
It didn't work for values over 0xff. Duh!

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 e569e40665 Forth-ify 2DUP 2OVER 2SWAP
2DROP was left in boot.z80 because it's used in icore.

Virgil Dupras bf49ca2ed2 recipes/rc2014: fix Makefile
It didn't have z80a anymore.
2020-04-20 19:22:43 -04:00
Virgil Dupras d466c6d95d emul: make stage2 load z80a from blkfs
This allows us to remove forth/z80a.fs. Another big step towards
self-hosting!

Virgil Dupras 6ae65940d2 Update bootstrap bin
It seems that I had forgotten in an earlier commit.
2020-04-19 20:57:09 -04:00
Virgil Dupras 0892193cbe Copy z80a.fs to disk blocks
I don't remove z80a.fs yet because build process needs it, but that
will change shortly.

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 a70366aa43 drv/sdc: Implement SDC!
This has been tested in the RC2014 emulator. I could edit blocks with
the Block Editor and they would correctly be written to SDC.

Virgil Dupras 47a7133b8b drv/sdc: Implement "SDC@" as a BLK@ word
"0 LIST" in the RC2014 emulator w/ SD card works!

Virgil Dupras f3c92684a0 link: improve reliability by never relinking last word
It's not possible to reliably determine its end and with some memory
initialization scenarios, it makes RLDICT fail.
2020-04-18 16:51:48 -04:00
Virgil Dupras 052c744000 drv/sdc: implement "SDC@"
I can read a block from blkfs in RC2014 emulator. It even checks
CRC16 successfully!

Virgil Dupras c64a8a2e2b drv/sdc: new unit to drive SD card through SPI relay
Goes through initialization in RC2014 emulator.
2020-04-18 11:11:11 -04:00
Virgil Dupras b062a9092a parse: use "0<" instead of "0 <"
As I wrote in my "Clarify signed-ness" commit, "0 <" is broken.

Also, made this unit a bit more compact. The RC2014 stage1 can
really use some breathing room...

Virgil Dupras 19d94dfb47 recipes/rc2014: stage1 is too big! saving some space
stripfc requires 2 spaces before "(" to strip a comment. This was
a low hanging fruit for me to get stage1.bin under the 8K line.

That thing is getting tight...

Virgil Dupras 9c41744e46 emul/hw/rc2014: implement blk write in sdc
All of that should help me implement sdc support much faster in
Forth.

Virgil Dupras ae470397d7 emul/hw/rc2014: add sdc emulator (wip)
so far, it goes through initialization with the rc2014/sdcard recipe.

Virgil Dupras eefa8e6de5 Add word "BLK!"
as well as emulator support for it. We can now write an edited
block back to "blkfs".
