	I didn't scoff, but I scratched my head for a bit....

	I'd like to thank you for posting that program because it uncovered
some flakey hardware in my system.  When I recompiled it to use my
'020/'881, it started going bonkers.

	Which brings me to the reason I ported this over to c.s.a.t:  I'd
like to bounce off you people what I think is wrong with my setup.  I have
an ASDG Mr. C with 2M of RAM in it, and a Ronin Hurricane card 14.foo MHz
'020, 16 MHz '881.

	When the ASDG cage is disconnected, everything runs great;
'Hopalong', as well as all other programs, run without incident.  When I
plug in the cage, vanilla programs run fine.  However, programs utilizing
the '881 are prone to random crashes, typically exception code 4 (illegal
instruction), 11 (line F emulator), and to a lesser extent 10 (line A
emulator), as well as one instance of 14 (format error).  Precisely when
these crashes occur is random.

	I suspect this is due to a combination of the kickstart tower PAL's,
and a flakey '881.  If it were just the PAL's, then one would expect ordinary
code running on the '020 to bomb randomly as well (which it once did before
I had the kickstart tower PAL's grounded).  If, on the other hand, it were
just the '881, then one would expect the random crashes to persist without
the cage attached.  Ergo:  It's both the PAL's and the '881 that need
looking at.

	Is my theory correct?  Is it close?  Am I from Neptune on this one?
