Welp, at least I learned something.  For whatever reason, I thought the
branch instructions worked on the acum and ignored the registers.  So I
probably would have never stumbled onto the reason by myself.  Thanks for
the help, and it works without a problem now (no big surprise there, eh?

Side note:  Eckhard, I haven't gotten your app to compile with MPW on my Mac
yet, but was only able to give it a quick go when I first tried to email
you.  I'm afraid my email is still being blocked by your ISP (both
addresses) so my attempts to email you bounced back (the second address

And there's yet another tidbit for this hobbyist to learn.  Didn't realize
that Thrust was an 8/16k game, nor that you couldn't cannabilize old carts
to make one.  How are you making these boards from scratch?  I'm afraid I've
mostly ignored the "Superboard" conversations as being threads that were
well over my head, and I suppose that extends to any bankswitched game
hardware.  Gotta walk before I can run, and I haven't even finished using a
good 2k of space personally -- so for right now even Combats are safe from

So any chance there'll be a limited run of signed Thrust carts? ;^)

Thanks to you both,
