This is my Macintosh Color Classic.
I purchased it from goodwill store NOT working.
I took a chance on if I could fix it and I did.
Works great now.

So I bought this Color classic not working. I assumed it was just the logic board ( motherboard )
That was bad as the capacitors on these logic boards are known to go bad.
So initially I was going to get it re-caped. So I put it away for a while to work on it later.

I found another auction for a Performa 575 so I bought it only to have it arrive shattered in pieces from not being packaged correctly.
So I decided to use it for parts.

I took out the logic board and hard-drive and put it into the Color classic.
And it worked. It would not work with the old hard-drive so I had to use the one from the 575 which
Is larger capacity anyways.

The 575 CPU operates at 33mhz as opposed to the original Color classic logic board with 16mhz CPU.

I also added more ram for a total of 36mb( 2x16mb + 4mb ). But I read it can also support 128mb.

I also added a NEW Network card. 8mb is all the ram that is required to use the Netscape web browser and go online
But more ram is better.

I purchased a NEW copy of Mac OS System 7.5.3 and installed it from 16 floppies.
( Painful , but it worked ).

And put on some new games.

Works great now.
I really like the tiny display. It works like NEW and image is nice.

I have 2 SCSI CDROM’s attached and several game pads.

Ah it's the "Mystique" upgrade, hrm yeah you could say that it's indeed a very extreme Color Classic.

Kinda sucks about the 575 arriving in pieces, but unfortunately with how plastic tends to become brittle, it's eventually going to become hard to ship these.

Yes, “Mystique” is what they call this logic board upgrade from a 575.
I plan on adding more ram up 128mb and a larger hard-drive.
This 575 logic board opens up allot of opportunities that were not available with the original logic board.

Is that an apple pippin controller i see?

Nope, Gravis Gamepad! The Pippin has a trackball in the middle of the controller, and a different shape entirely.

I finally finished upgrading this computer.
With more RAM, Bigger hard drive and NEW apps and games.
This computer from 1993 can still go online and works great.
All that is needed is 8mb of ram and Netscape web browser 3x

These 500mb hard drive upgrades really made a BIG difference in my setups.
I have lots of room for games and apps now.

I have a Macintosh Color Classic and when I bought it a couple years ago it worked perfectly. Then, a couple years later I decided to try it out again. It didn't work, and it turned out the caps were leaking. I took the board out, washed it down with a paint brush and slight soapy water in the sink, let it dry and it worked again! I know this usually is a temporary fix. Now I tried it the last time a couple months ago and it works with a boot disk, but the hard drive seems to not get noticed. I can hear it try to start, the motor turns but then dies out. It does this several times trying to start, but no go. Its as though the Hard Drive is not getting enough power?

Could this problem be related to the caps, even though it looks like the hard drive is not getting enough power to turn on? The board seems to work fine, so I am confused. I am wondering if caps could be gone in the power supply, not allowing enough power to the drive, or could the caps on the board effect the turning on of the Hard Drive? Any help or suggestions would be greatly appreciated. May be a mystic upgrade is in order until I fix this boards caps? Thanks in advance!
