Reducing Noise on the IIgs (Fatal System Error 0911)

["Matthew S. Carpenter" <superpsycho@comcast.net>]

Hello,

I recently upgraded my TWGS accelerator with a 32k cashe card.  After 
doing this My IIgs has been giving me Fatal System Error 0911 with a 
fair amount of frequency when I try rebooting the IIgs to different 
drives and sometimes when I try to go into the control panel.

After looking it up in the CSA2 FAQs I think it's likely due to noise 
problems or dropped voltages. 
<http://home.swbell.net/rubywand/Csa2HDWHACK.html#005> I have in my 
Apple ROM 01 IIgs: a LanceGS card[2], a TWGS[3], an Apple High Speed 
SCSI card[5],a superdrive card[7], and an 8MB Serius RAM card.  I've 
already done the power supply mod as explained here 
<http://home.swbell.net/rubywand/Csa2POWER.html#005> but the errors 
persist.

I was going to try adding wires to make the path from the power plug to 
the slots on the board fatter but I don't think I'd be able to do it and 
not have problems with shorting or crimping from supports in the case. 
<http://home.swbell.net/rubywand/Csa2POWER.html#006>.

At this point I would really like to find someone I could take my IIGS 
to who I could pay to do this...or send it out if I had to. I'm in Kent, 
WA... 45 minutes south of Seattle...

I could either pay in cash....or in trade... I have some extra Apple II 
and Commodore equipment I don't need.(though not near as much as I did a 
couple years ago)
