Well, I've gotten the overheating and RAM problems solved, but there's one
more minor problem that I'm having:  sometimes, when doing a cold boot the
deinterlaced image has garbage overlayed over it and has a general purplish
tint.  Shutting off the computer and turning back on about a second later
gets rid of it every time.  Turning it on any time after ~1 minutes results
in the screen garbage, but again it is cleared using the above technique.
Any time that the display-enhancer is not used (the productivity modes, or
when it is switched off), the display is garbageless.  It is also free of
any problems when the display is simply scan-doubled (eg. a 640x200 screen);
dragging that non-interlaced screen down to reveal an interlaced screen does
bring up the garbage.  It happens under both 1.3 and 2.0.  I've also check
the cable half a dozen times;  I'm sure it's not that (this problem never
showed up on the 3000 I had replaced).

What I'd like to know is:  does this sound like a problem with the Amber
chip?  If so, I'd be inclinded to just let it ride (it's not really a
hardship) until I take the machine in to get the 2.0 ROM upgrade;  I'd
have my local dealer replace Amber at the same time.  If it sounds more
serious, I'll make the trek to the dealer that I bought it from (1 hr.
away, plus the time needed to remove the extra hard drive and 3Mb of RAM
I've added and reinstall it all in the new machine) and get a replacement.

Thanks in advance for your advice & suggestions.
