Virgil Dupras da371451cc 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...

Virgil Dupras 73482e7ea1 Reword root block 
Usage of "LIST" wasn't explicit enough for a complete newcomer. I
hope that with this wording, anyone can figure out how to navigate
blocks and learn the system.

Virgil Dupras 2791dd992e ti84: offset binary by 0x100 to free space for TI-specific stuff 
Not yet tried on real hardware, but we should be getting pretty
close...

Virgil Dupras 62ae1012df ti84: allow case select during a-lock with 2nd mode 2020-05-10 11:39:10 -04:00
Virgil Dupras a6aba40327 ti84: fix a-lock debouncing bug 
Yup, it was a deja vu. I remember now.

Virgil Dupras 06a4674317 ti84: implement a-lock 
There's a bug where the first char after a-lock isn't a-modded. I
have troubles figuring it out for now. It feels like deja vu. I
think I had the same problem with asm.

Virgil Dupras 2f1e635b9d ti84: tidy up driver code 
Pushed all words directly interfacing with ports and memory offsets to
low level layers. This saves us the need for keeping those variables in
runtime memory.

Virgil Dupras b2d71cb1ee ti84: add Z offset mechanism 2020-05-09 08:13:49 -04:00
Virgil Dupras afc2327770 Split icore in 2 parts 
The goal is to insert device drivers in between.
 2020-05-08 21:47:03 -04:00
Virgil Dupras baf725aa38 Move a bunch of words from core to inner core 
That makes it easier to write drivers that can be xcompiled.

Virgil Dupras ffdc58739a ti84: HelloWorld! 
In emulator of course...
 2020-05-08 11:36:50 -04:00
Virgil Dupras b90efb0f7f ti84: first glyph on screen! 
On the emulator of course...
 2020-05-08 09:07:44 -04:00
Virgil Dupras 58ec54fc97 ti84: wip 
Gave more priority to CPU in the emulator because initialization would
otherwise be horrendously slow.

Virgil Dupras 4e98ef11bd ti-84+: wip 
I need RSHIFT and LSHIFT first...

Virgil Dupras feb0411530 editor: simplify I with the use of MOVE- 
Also, delay the shadowing of DO..LOOP's I for as long as possible.

Virgil Dupras 690d9e6313 editor: improve I 
Make it print edited line and also have it adjust cursor pos.

Virgil Dupras 58ece9f9a1 editor: implement I command 
Also, made LIST properly handle full 64-chars lines not ending with
a null or CR. Previously, such a line would be accompanied by its
following line, duplicating that line's output.
 2020-05-06 12:19:36 -04:00
Virgil Dupras f54b1dc504 Add 2>R and 2R> 
This allows us to make DO..LOOP more compact.

Virgil Dupras 60b4bbf28a Fix DUMP's broken "round up to next 8" logic 
This was caused by the removal of signed-ness a long while ago.

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.
 2020-05-05 20:10:04 -04:00
Virgil Dupras fa79e3d8a6 Make (print) stop on CR 
Lines edited with the Block editor end with 0xd and (print) spits
spurious CR when printing those lines.

Also, properly initialize ACC in BROWSE.

There was a weird empty block in the middle of the program.

Virgil Dupras a96b5f1dec Restore DOES> section in usage guide 
I removed it because it was redundant with Starting Forth, but
I directly reference it in the dictionary, so well...

Virgil Dupras 5504c796ee tools: add blkup 
With this tool, we can send content to a TRS-80 directly to floppy.
This paves the way to writing ourselves a set of disks containing the
blkfs!
