Virgil Dupras 372524fd19 Move xcomp to blocks 2020-04-21 20:30:14 -04:00
Virgil Dupras 4967c2add2 Merge z80c.fs and boot.fs into boot.z80 2020-04-20 21:27:34 -04:00
Virgil Dupras bf49ca2ed2 recipes/rc2014: fix Makefile 
It didn't have z80a anymore.

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.
 2020-04-11 13:31:17 -04:00
Virgil Dupras 6368cc3bac Remove (sysv) 
Replace its usages with direct RAM+ offsets. The (sysv) mechanism was
incompatible with cross-compilation of a full interpreter.

Virgil Dupras 92ddc7ebc1 recipes/trs80: use grid module 
Not much of a gain in terms of usability (a bit of a loss in fact, things are
a bit slow and glitchy), but it's a necessary move if we want to use upcoming
grid-enabled userspace apps, such as a visual text editor.

Virgil Dupras ec6df3087d recipes/trs80: add "recv" command 
This allows us to write contents from RS-232 directly to floppy! it works!
 2020-02-22 14:43:07 -05:00
Virgil Dupras 049f2cf222 Reverse ttysafe escaping order 
Sending the escape after its target made things complicated for upcoming
stuff I want to add. Although it makes `recv.asm` slightly larger, it's really
worth it.

Virgil Dupras 438c71ad3d trs80/floppy: new module 
Read-only support for now, hardcoded on drive :1. But it seems to work.

Can't wait to get a CFS running on this!

Virgil Dupras bd38d46892 recipes/trs80: fix double line feeds 
Lines should be terminated only with a CR on this system, not CRLF.

Virgil Dupras fb2117dc2e sms/vdp: use fonts from kernel/fnt 
Instead of its own version of one. Additionally, add a 7x7 font to
the collection.

Virgil Dupras c7ef8bf915 recipes: add "make emul" targets where appropriate 2020-01-02 16:59:38 -05:00
Virgil Dupras 9216057db8 emul/hw: add TI-84+ emulator 
I implement the screen using XCB which is much more friendly
than z80e's SDL+CMake for development machines that want to install
minimal dependencies (for example, a port-less OpenBSD rig).
 2020-01-01 22:48:01 -05:00
Virgil Dupras 097c677641 emul/zasm: use libcfs 
This allows us to get rid of the zasm.sh wrapper.
 2019-12-31 15:07:39 -05:00
Virgil Dupras dcb96aefe9 lib/parse: remove parseHexPair 
Also, make parseHexadecimal "tail" (HL). Soon, all routines in lib/parse
will do that, making the life of lib/expr easier.

Virgil Dupras 5b155a5c15 tools: use BASIC's new while loop 
Also, increase STDIO_BUFSIZE to 0x40 so that those while loops work.
