I've been working on my Power Colour Classic for close to a year now. I finally got the regulator circuit up and running but my 6360 board is giving me video related problems. Basically just at the point where extensions begin everything appears to go dead on screen apart from a tiny inch long row of pixels in the top left corner. It otherwise finishes booting and works normally. I can use the power key and return to shut down etc etc. A 6200 board has none of these problems but I really don't want to be crippled by this dog like board I'd particulatly like the 6360 to work as I paid an outrageous price for it!

Anyway what I need to do now is track down someone either in Melbourne or, say on this side of Australia, with a working 6360, 6400, 6500, 5400, 5500. If I can find someone with one of these I would like to try my board in it to see if it still works properly. If it's in Melbourne I could arrange to meet up, if it's insay Sydney I could post you the board and provide money for return postage.

If you want to find out more about the problem I started a thread at Applefritter in the Colour Classic Forums, something like 6200 works 6360 not quite.

I'd really apprecitate any help, if I can get this going in the next 6-8 weeks it'll be one of the few projects I've completed in under a year!!

1) Bad Extension: Have you tried starting with extensions off? (Hold down the shift key during the power-up.) You might have an inappropriate extension that you will need to remove (my bet is that it is one of theo "load me first" extensions whose names start with spaces).

2) Thermal Hardware Problem: Does the same sequence/duration of behaviour (normal screen, then pixel strip) occur on restarting after the machine has been on for for a few minutes? If so, its probably NOT bad hardware fault because if it were, the unit would stay in pixel-strip mode after the first startup/warmup.

3) It could be an incompatible video mode. On some system configs (OS 8 and later, IIRC), the machine switches video modes during start-up. This might cause it to use a good resolution setting intially, but then use a bad setting later. (try booting from a system floppy or CDROM)

4) Zap PRAM, hit the CUDA, yada yada yada.

Keep a stiff upper lip!

What would be good is if I could find a repair disk floppy image to boot from.

There is also the fact that 99% of my mac software, particularly my old software archives are in the UK

Finally I haven't really used a floppy in almost 2 years, since I got my first CD burner

Plain and simple, floppies are evil, that's why I'm ditching the floppy in my latest 68k Mac Hack. Incidentaly that's been progressing well but a lack of funds means I can't get everything I need to build the new housing.......

EDIT- Actually I know I could have downloaded one from Apple but at the time I was thinking it would only be possible to get a 7.5.3 disk image. What I would like is a 7.6 disk image but now that I think about it 7.5.5 might do the trick, I'll download one later.

I know what you're saying though - I hardly ever use floppies except to boot from (that goes for Macs and PC's) Bootable CD's are cool, except that it's hard(er) to make a custom boot CD that works smoothly - say a Norton type CD with appropriate preferences set in the System Folder (that really screwed me up the first time I tried)

If you end up needing an OS8 boot floppy...let me know

cheers
Flash!

You just reminded me, I'm 99% certain that my Norton 5 Disk uses has a system 7.6 system folder on it! I'll report back later!

I haven't used Norton in so long! I forgot version 5 has an OS 9 system folder, it must have been 4 that used 7.6 (I'm sure I had Norton 3 long before 7.6 came out though).

I just tried out a friends OS 7.5.5 setup disk, it was meant for the 7300,8600,9600 but I thought it would have worked, but it didn't.......

Does anyone have a 7.6 disk first aid (or simillar), disk image?

Good luck!
