This happens if the ROM cant see the SWIM. grab the classic schematics and go throught it. Your not gonna see via corrosion AFTER you already washed it. You needed to take note of…

Thanks for the suggestion, I don't get a flashing ?, yet.  I removed the RAM card and it did not help, in a separate attempt, I removed the HD cable and the startup remains unchang…

As long as you got the flashing '?' inside a floppy disk icon, the Classic is or should be working. You got a Bong an you got video - that's 2 out of 3, which the third is booting.…

Could be the HD, try disconnecting it and booting from floppy

Its weird that only text is having a problem. That and the ROM checksum is passing. The only other chip I can suspect having a problem is the MEGA II which contains the character g…

It actually looks like what my vision does to me, from time to time. lol. But I digress.... double data = missing upper address bit/select signal on character ROM. 

And it can run my Leopard developer preview!

I do actually have one of these floating around somewhere in one of my stacks, might actually do just that!

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…

I have been unable to find out what the CFM and the dBA of the original Color Classic fan is.  While I am doing an upgrade, I would like to move more air and perhaps use a fan that…

Yes, advantage of a TiBook! Also, 100GB is overkill for OS 9, but just enough for Leopard. *And* I can run my library of old Mac software (1983/4-1999 I think, maybe later than '99…

Schmoburger.... Point well taken.  I restore old vacuum tube motion picture amplifiers for a hobby 1930s-1950s equipment.  I keep them all original.  I would prefer to drop in a …

9.2.2 should fly along beautifully on the 1.0 Ti... not entirely sure about Leopard's performance however. I know as much as it will run, however it may be a little painful as I do…

My weapons of choice are 9.2.2 and Leopard

For what it is worth you likely will not hate the experience as much as you might expect if you play your cards right with the initial setup... I actually go out of my way to use t…

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.

I think this is on! Perhaps June will be PowerPC month .

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…

I use my 3 G4 iBooks (2), PowerBook (1) and my G4 Tower for everything everyday since I acquired them long ago. I do have a iMac Intel Mini but do not have a working PSU for it. S…
