8bf6258673 Add word TICKS 
Adding a delay such as the 20ms one we have in AVR programmer's
initialization routine is tricky without a word like TICKS.

This implementation is highly inaccurate, but more accurate and
reliable than a "ballpark" DO..LOOP...

25a35cf28e Move 8086 boot code from B800 to B440 
That slims down blkfs a lot.

b21be43535 Move 8086 assembler from B730 to B30 
Also, move doc to doc/asm.txt.

Also, fix the pcat recipe which was broken since the overlay change.
I hadn't noticed it because I didn't have to rebuild the MBR.
