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.

6368cc3bac Remove (sysv) 
Replace its usages with direct RAM+ offsets. The (sysv) mechanism was
incompatible with cross-compilation of a full interpreter.

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.

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.

9216057db8 emul/hw: add TI-84+ emulator

minimal dependencies (for example, a port-less OpenBSD rig).
