e6bac985fa Cross-compiles in a single stage! 
Finally got rid of the XPACKed core and managed to cross-compile
all core words, which greatly simplifies the bootstrapping process.

7c20501f27 Move core's blk to xcomp core (low and high)

Now more low/high layers.

cbf5baf3b6 Pack core words a bit 
This leaves space for xcomp-core which is growing.

dfe474ca0e xcomp: add XCOMPILE and X[COMPILE] 
This allows us to move words like ABORT" to xcomp-core, which is
I think the last roadblock before being able to unify all drivers
into a single xcomp layer.

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...

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...

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.

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.

58ec54fc97 ti84: wip 
Gave more priority to CPU in the emulator because initialization would
otherwise be horrendously slow.

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.

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.
