Still bombing out at the same place:

401002a :  [ 0xe34 ]

byte-load: exception caught!

: xe33  $find invert IF ABORT THEN ;
: xe34
  " us" xe33 TO x9a7
  " case-closed?" $find invert IF 2drop ['] 0 THEN
  TO x9a8 ;

So the thing that throws is fcode e33, when trying to find the word "us".

(Btw, "invert" is weird here; I suppose it was coded as its synonym "not".
In some other Forth systems "not" is a synonym for "0=", which makes more
sense here.  Either works as long as $find returns a canonical true/false,
as it supposed to).

So, implement "us", and you'll get further :-)  It's just like "ms", but
microseconds, instead; so you could do

: us ( n -- )  d# 1000 / 1+ ms ;

(which waits way too long for short timeouts, of course).

Ok, thanks, that makes since. I did see the “case-closed?” When I searched for 0xe34 in the detoked rom, but I wan’t sure what to make of it.

So, the “us” word is unimplemented in Openbios, and we need to add it to get past this part?

Exactly.  And I gave a (not super great) implementation above, enough to
see if you get further :-)
