Hi John,

I've done that, but for some reason on Atari boards, the NOP configuration
does not yield stable signatures. So far I've been too busy to figure out
why, so I just use the CAT box. However, it does work well on Space Inva-
ders.

Cheers,
Mark

P.S. Come to think of it, it may just be the phase difference between ph.1
      and ph.2 of the clock. With the CAT, they're in phase, but with the
      NOP they're not. Note to self: check the clocks.
