Virgil Dupras 78b9f89950 Update README: Forth reboot in process 2020-05-04 08:28:56 -04:00
Virgil Dupras dcd68fc40b forth: transform (find) into FIND which is an indirect call 
You'll see where I'm going with this...

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 7544b3834b emul/hw/rc2014: implement blkread in sdc 
I now get to "fls" in recipes/rc2014/sdcard!

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

Virgil Dupras e37f4c2551 bin2c: add missing stdtypes.h 2020-04-07 18:13:42 -04:00
Byron A. Grobe 217df20d77
Moved tools/bin2c to single-level with other tools. 2020-04-07 16:56:55 -05:00
Byron A. Grobe f65c189e9b
Replace bin2c.sh with a more portable implementation. 
`xxd' is not available on all systems, and on others does not support
the `-i' flag. Since bin2c.sh relied on a tool that I can't seem to find
a compatible version of, I have included a simple, portable replacement in C.

Usage remains the same:
bin2c ARRAYNAME < inputfile > outputfile.

This change is also reflected in emul/Makefile.

Virgil Dupras e284081c79 forth: fix readln overflow handling 
It was badly handled.

Virgil Dupras 941791d609 forth: remove RAMSTART and RS_ADDR from stable ABI 2020-04-02 11:39:40 -04:00
Virgil Dupras 2481ed4b66 forth: remove dummy.fs 
All "stop pings" are now explicitly made at appropriate places. This
fixes a problem I've introduced in the last commit where RAM+ was
unexpectedly part of a stable ABI because of "HERE" usage in dummy.fs.

This system will, anyways, soon change because boot.bin and z80c.bin
will be built during the same process (but there's a bit of retooling
to do before I get there).

Virgil Dupras 68a7be3707 forth: Remove RAM offsets from stable ABI 
Doing this was a bit stupid. These offsets are constants. Moreover,
having them in stable ABI had us construct the boot binary from the
stable ABI of the host, making it very difficult to change RAMSTART
for a new system.

Virgil Dupras d0c5d3a741 Forth self-bootstraps!!! 
This commit cuts Forth's dependency on zasm. It now self-assembles
its own boot-binary! Things are a bit messy now, I'll clean up
later.

Virgil Dupras e846d07238 forth: simplify build process 
Make LATEST configurable through a value in the binary instead of through
a ZASM constant. This enables the simple concatenation of compiled dicts and
simplifies the build process.

Virgil Dupras 5c03b33982 forth: remove sysvarWord type 
Not needed anymore. CONSTANT does the trick.

Now we're having a real nice and tidy forth.asm...

We refer to stable offset as direct numbers instead of offset to JTBL.
Simpler that way.
