Virgil Dupras 2d9a07d215 blkunpack: don't include trailing empty lines 
This was becoming heavy to manage.

Virgil Dupras 1b5333d0b4 pcat: move all find code in _find word 
It isn't used by low level boot code anymore, so it can go there.

Virgil Dupras dbd283758c Refer to BOOT and (uflw) by addr in stable ABI 
Was previously referred to by name+find, which was wasteful.

Virgil Dupras f6ded7712e VE: add 't' 
This is the first commit I do entirely in VE. It's a habit I'm planning
on taking as it helps a lot to find usability issues.

Virgil Dupras 2d17b4e8ec Make string length-prefixed instead of null-terminated 
I'm not sure why I chose null-terminated initially. Probably because
the z80asm version had null-terminated strings.

Length-prefixes strings are the traditional form of strings in Forth
and it's a bit easier to work with them with traditional forth words
when they're under this form.

Virgil Dupras f75b1c8864 Add word ?DUP 2020-05-22 14:19:02 -04:00
Virgil Dupras bd38d80f9c Move Cross-compiled core from B390 to B350 
and renamed it "Core words". Also, reworded the presentation.

Virgil Dupras bd1e76ec5b Gather all RC2014 drivers into a single "RC2014 Recipe section" 2020-05-13 14:56:38 -04:00
Virgil Dupras 8d78ca9dac tests: add test_sdc 
The SD card driver is a bit too slow to be bearable. I'll write
_crc16 in z80 and see how it goes.
