upgrading Apple Colour Classic

[Mac128]

What does a CC with MacTV logic board identify itself as being? A Macintosh TV?

You know I never thought to look, or if I did don't remember. Unfortunately I can't get the answer easily and will need a weekend or two to pull both out and check.

When you say res-edit hack, do you mean to the system?

Whatever it is, the logic board is telling the analogue board directly to produce 640x480 (I don't think the Mac TV will do 512x384, but can't remember), so it could be coming from ROM, in which case, I suppose a hack would do it, but something tells me this is not the case.

nope 1 faulty cc main pcb WELL I TRIED :disapprove:

My Macintosh TV logic board will drive the Color Classic at 648x480

this sound very cool am guessing 648x480 @ 67hz

was it full screen??

Except that is a MAJOR hack, requiring significant modification surgery not for the faint of heart.

And performing an unsupported hack on a Colour Classic board isn't?

Perhaps this has been mentioned before, but I didn't see it in a quick scan. You will find a wealth of information about upgrade possibilities at http://colourclassicfaq.com/

There is/was also a wonderful site by Stuart Bell. I now get a "404 Not Found" error, though. I hope that this is a temporary outage -- his site is full of valuable information (and great photos of successful mods).

And yes, long live Robby!

And performing an unsupported hack on a Colour Classic board isn't?

Having performed all but the 575 analogue board hack, I would say the others are minor hacks by comparison.

FYI, the stock Colour CLassic board will support stereo sound output if a duplicate set of components are added, namely a second Sony amplifier. I have done this by cannibalizing one of the channels from the 575 board. Wish I had heard of the 575 hack before I did it as it would have solved a whole host of problems.

But I am really curious to know what is happening with the Mac TV board (and yes it was full screen, not sure of the exact HZ though). Is it in essence allowing the CC analogue board to produce the larger resolution somehow within tolerances, or is it inducing the same strain as the VGA mod (or is it the hi-res mod, I forget which)? If the former, then it would be a nice secret to learn for all CC mods.

It's been down for a few months, alas. There's a couple of onoes! threads about it on Applefritter, and a rallying of the troops to rebuild it from archive.org and google cache. No idea if anything came of that.

archive.org, meanwhile, has a reasonably complete backup of Stuart's PCC site. Some versions of it are missing some of the photos, but otherwise it's all there.
