Thanks to the convenience of digital cameras, I've finally got some pictures of my Takky to post.

Also, I felt guilty letting jt carry so much of the hacking content here. Wink

CC in all its glory

My Colour Classic Takky, in all its glory.

Inside is a 6360 logic board. I used the VGA mod on the video. The internal speaker was replaced with one from a Powerbook 520. The speaker sits in front of the 630 harness.

Also noteworthy, if you look to the lower right, you can see a concrete stepping stone I made out of Pentium I and 486 CPUs
CC back
The Colour Classic from the back. Two PCI slots available, one with a 10/100 ethernet card.
CC where the mobo go
Here’s where the motherboard goes. The frame of the CC was cut in such a way that the 630 harness it tabbed, so it can be removed easily by pushing some of the frame plastic out of the way.
Thanks to the two-slot PCI riser, there’s pretty much zero space for anything on the right side.
The floppy housing was cut to allow the video input card to fit, and now has a small screw holding it in place, as the mounting tabs were cut off.
The yoke's on you
The real guts of the analogue board.
To the left is the slim 3.5″ 1 gig Seagate SCSI drive, and to the right of the yoke is the extra power supply from All Electronics powering the hard drive and supplying the 3.3V necessary for the 6360 logic board.
A rat's nest of wire
Here’s the messy wiring that make all these extra bits get along.
Just to the left of the yoke is the 12V relay that turns on the second power supply.
I'm quite pleased with the system. The only hiccup I still have to address is the sound is distorted - the PB speaker obviously isn't up to the task, and there's interference on the screen when the drive heads move, which I'm hoping I can solve by modifying the shielding.

Oh yeah, I can't edit the first post.

CC - Nekkid
Another view of the insides. Mounting metal for the secondary PSU and the hard drive was cut from a donor Pentium case.
The metal is screwed into the top CRT mount on each side, and the bottoms are tabbed to sit loose on top of the plastic frame.

Nice Photos! Thanks!

Ever thought of going for a x500/300Mhz board and getting even better performance?

Go Speed Racer!

I need to give it an overhaul before I consider upgrading it. Before I went for a speed bump, I'd first want to invest in a 2.5" drive to replace the 3.5" one, and a laptop CD drive - both might fit in the floppy area...maybe. My hope is that moving that big hard drive away from the CRT would eliminate the screen interference from the heads. If it doesn't, then there's grounding or load problems with the aux. PSU, and I'll need to address that.

I may add some more pictures. I was thinking that the 630 harness frame mount might be useful, though it's really just based on your work.

Shoulda "bump-posted" . . .

. . . so you could edit . . . at least until somebody responded. Evil Block Company

GREAT job, e! I haven't been in the CC forum for quite a while, so I hadn't seen all these pics yet, it looks fabulous!

Has anybody got the actual pinouts for the CC (or 575) AB connector? I found the video line listing for VGA conversion, but I'd like to nail them all down before I start. I'd sorta like to turn my newly acquired 575 freebie into something like your CC, but it'll have a custom crossove A/B switch setup. That way I can run the 575 monitor off the 6360 mobo normally or switch to an external feed (or loop back the 6360's Radius PCI card's output to the 575 CRT) and watch movies on my 21" monitor.

Do you mean this guy? You'll have to reverse the diagram layout, but most of the pins on the CC/575 AB are identified.

Nope . . .

. . . there is something seriously funky about those pinouts. I'm sure that layout makes sense from the CC hacker's perspective, but it doesn't look at all kosher to me.

jt :?

edit: erm . . . prolly cuz I'm lookin' at the wrong ten pin connector. I wonder if this is why my tuner card stopped working?
