6bc1738bfd pcat: implement (loop) 
8086 asm is a lot terser than z80... Those indirect memory operations
are very handy.

d8d2e05eb2 pcat: make find compare strings 
find is the biggest chunk of logic of the boot code. The 8086 version
is significantly terser than the z80 one. REP/CMPS helps...

8c452f5add pcat: begin implementing find 
Not comparing strings yet. Without asm tooling support, it's a big
chunk to swallow at once. It's progressing well!

2b7abf802f pcat: begin porting forth 
I'm not sure yet where I'm going, but I'm not going to build the
8086 port from the ground up like I did with the z80, that is,
making is sustain itself and eventually merge its forth code with
core words. That would be too much work which would then be thrown
out (all those words I'll initially have to implement in asm which
are already implemented in Forth).

What I *think* I can do is build a mirror version of z80 boot code
and cross-compile it from the z80. This means it has to follow z80
stable ABI.

Nope, I'm not sure where I'm going...

07e50313c7 pcat: separate MBR code and OS code 
MBR code now strictly loads OS code into memory and jumps into it.

Now, I've got to consolidate my assembler code, modrm logic is
messed up.

b2b556911f trs80: implement AT-XY 
Also, I've run VE on the TRS-80 for the first time! It doesn't work
well though. Screen is mostly blank all the time.

I removed instructions from the recipe which became obsolete when
Collapse OS became 100% bootstrapped. Also, I've updated instructions
to change the NL override which is necessary for blkup to work.
