I stuck mine in a G3 desktop.

I can make out "System Good" on that image, but you say it freezes at that point? Interesting. What cards are you running on the IIgs? Have you run it without cards? If it were a…

Hmmmm that's what I was thinking, that it might be actually logic board related rather than the Targa card itself. I might actually bring the 7600 over later today and throw in the…

I tried reseating the chips and no luck. I'm not sure how to clean the sockets honestly. The problem is also present on the composite output. The monitor is an Apple RGB monitor …

For some reason I'm recalling some other issue on some of these boards that caused slot problems. Each pair of three has its own controller.

Looks like the AppleColor RGB monitor the IIgs is paired with normally. There is no character ROM on a IIgs, it is stored in the main ROM. Have you performed a self-test? Hold down…

So I booted up the 9600 this evening and it froze before the icons appeared on the desktop, which I discovered  after I turned back around to open up Classilla and check something …

What kind of monitor is this? Have you tried it on a Composite Monitor? If not, check your VGA Settings. 

Hi folks... I have a technical question (?) on Chris Lawson's VGA mod of the Color Classic.: http://colourclassicfaq.com/general/vga.html First, I would like to quote a post mad…

I'd remove the socketed chips, clean contacts and reseat first

I've had a "Mystic" VGA-modded Colour Classic with LC575 board which has been running fine for a decade, and it's one of my most used 68K Macs.  I was also given a "Takky" VGA-modd…

You can find 10" "flatscreen" monitors out there, but you'll have two problems to overcome. The flat screen won't fit the very curvy bezel that housed the very not-flatscreen Sony …

Well it increases the current tails in the horizontal output circuitry so it swings the beam harder.  But the problem with this, it adds stress to the sweep circuitry so eventuall…

I thought about this. Can you tell me which one is it? Just so you know, I also replaced the VGC chip and it made no difference. Thanks!! Pitou

My guess would be something with the character ROM?

Hello, I have an issue with an Apple IIgs. The text is kind of doubled in Text mode. When I boot a system disk, in graphic mode, everything is fine. I have some experience in elec…

I have read that the flyback transformer in the Color Classic was slightly undersized to began with.  And then, because of venting issues, it became slightly hotter then it would l…

I don't own a CC and haven't done this modification, but I've looked at the horizontal sweep circuits of the B&W compacts in some detail. I think the CRT shouldn't be your…

Hi... My TV is the very last CRT HD Sony TV.  Deep, deep blacks, and pure whites.  Yes, it is only HDMI 1.1, but I love the 1920 X 1080p picture. No motion artifacts. I am gettin…

Yea, I know... I fubared that one up pretty good. But, oh well... 

OK, I love the attempt at being a wiseguy, but TK, you typed THE ENTIRE URL into the google search box.  LMFAO

Hi... I would like to pull the analog board in my Color Classic.  Any one know of a web site (that is not dead) that has good photos of this?  I have the Mac Service manual, but t…

You try another known good working drive? I would hope so.  Otherwise, did you check the DMA lines that bounce between the SCSI IC, GLU, and VIA? 

I checked all traces going to/coming from the SCSI IC, they are fine.
