Re: reviving an Apple IIGS...

[Krishna Sadasivam <kms007@gmail.com>]

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 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.

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.

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