Thanks for the welcomes, everyone!

The hard drive spins up, but frustratingly enough - GS/OS boots midway
before getting stuck during the thermometer process.
When I first opened up the IIGS - there were loads of dust bunnies. I
cleaned it out with a few quick blasts of compressed air. I also
opened
the external drive to make sure it was clean. So far so good.

At this point, since I can't quite boot my hard drive, I've been
eyeing a CF card based solution. Any recommendations on which one
would
serve me best? The price points are roughly equal, so I'm interested
mostly in hearing about reliability and support.


I'm a satisfied CFFA customer--Rich has done a fantastic job of keeping
his early customers current, and has steadily improved the design.


I'm hoping (and this is a big hope) that with the CF card, I can boot
a clean version of GS/OS 6.0.1 and see the volumes that are on the
80MB
HD I have. If I can copy that data over, then I'm okay.


That's exactly what you should hope for!  I'd give that HD a rest
until you're ready to block copy it to a CF card and attempt a full
recovery or just file retrieval.

Until then, I'd avoid anything that might write to it...


My Second Sight board seems to work okay - but with an LCD (I'm using
a Hanns-G 19" model) - I was seeing a lot of wavy lines when
attempting to boot from  GS/OS on my hard drive. Weirdly enough, I
didn't see this when accessing the built-in Control Panel or anything
ProDOS based.


The dot clock on the IIgs is 16MHz in SHR modes (like the GSOS display),
but 14.3MHz in all the standard Apple II modes.  It sounds like your
monitor prefers the 14.3MHz modes.


I'm incredibly rusty with the IIGS - I used to know it like the back
of my hand, but I'm having to Google information to jog my memory
back.


It's like riding a bicycle (for the mind ;-).


I'll keep everyone posted on how things develop. Thanks in advance for
those CF card recommendations!


Good luck!

I should also note that the RamFAST utility appears to lock up from
time to time when I am in it. (I'm holding the 'zero' key to access
the onboard RamFAST utilities. I will add that my hard drive now
appears to boot into my System 6.0.1 partition (albeit very slow...) -
(it may have taken some time for it to 'warm up', being dormant for
the better part of a decade). It freezes after the thermometer.
I need to check if the ZipGS card is functioning or if the machine is
crawling at 1MHz...
The adventure continues.

I'm in the process of setting up my IIgs again but mine has only been
down for a number of months, not years.  :-)
The last time I had my machine set up, I was trying to modify a flaky
ZipGS to a higher speed but never got it running reliably.  Last week,
when I put my regular ZipGS back in, it wouldn't start properly (similar
problems to what you experienced above) but by pulling the card from the
slot, disconnecting the ribbon cable from the card, removing the ribbon
cable from the processor socket, putting everything back together and
then flexing the card and/or ribbon cable a couple times (the ribbon
cable tends to bend the ZipGS card away from the power supply if the
card is in slot three) it has started working again.

The processor socket-to-board connection seems to be a well known
design weakness in all IIgs accelerators...


Actually, I meant the entire path from socket to accelerator board:
the processor socket, the plug, the cable, and the header plug...


Cable, too, especially if it's been folded(pinched) numerous times.
That breaks the conductor inside the insulation. I've run into that
quite a bit on many different interfaces.
