Virgil Dupras 1bd191e86a Move /emul/forth/* to /emul
Less noisy this way

Virgil Dupras f19a5e1f71 Remove recipes/rc2014/zasm
That becomes irrelevant in Forth

Virgil Dupras 44403c3d4c Move icore to blkfs
The way is clear for complete stage1 bootstrapping on the RC2014
target!

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 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...

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.

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 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!
