    Color Classic VGA Mod. the CORRECT way

    The Macintosh TV issue was that, though I fit in the CC, the Analog Video board was not powerful enough to provide power to everything. I popped it into a the Performa 550 and booted up perfectly.

    I have repaired 3 CC Logic Boards, 1 Macintosh TV LB, and 1 LC 520 & 1 Performa 550 LB. I used clippers to clip the old caps off the boards. Clipping at the center of the Cap. I then used a flathead screwdriver to carefully remove the bottom portion of the caps. I left the metal poz & neg leads/posts left from the old cap still soldiered to the board. (removing them when I was ready to put on the new Caps) Then ran them through the dishwasher as outlined earlier. I shook the boards to get as much excess water off (even though I had the dry cycle on) and put them in a dish drying rack with a fan blowing directly on them. I started with the Ports facing down to ensure any water trapped in the ports would drain out first. I rotated them every 6 hours. After they had a good 2 days of a fan blowing on them, I was sure that they were dry. Then I soildered on the new Cap's. It was easiest to put a bead of solider on the poz and neg terminals of the new caps first. Next I started to remove the old Cap leads/posts using resin were needed. (BE VERY CAREFUL - you can easily lift the metal pad off the logic board if you're not careful. Then you'd have to do a trace repair; which can be a bitch) Finally I got the new Caps on and popped the new batteries in. All boards worked. The one that lost the startup chime still didn't make sound though the internal speaker. But external speakers work fine. (had to get Stereo to Mono adapter for best sound.) I'd like to point out, that the Macintosh Performa or LC 520 & 550 logic boards work in the CC without any changes. Essential the LB from the 550's is the same as the Color Classic II @ 33MHz. The 520's are 25MHz, which is still a hell of a lot better than the underpowered 16MHz of the original CC. The thing that took to longest for me was sourcing the Caps as I wanted to use SMD/SMT Tantalum Chip Capacitors. They were only shipping from china off Amazon. I purchased them ahead of time so I'd have them right after the boards were done drying.

    Bump on Schematics?

    Okay I wash the boards in the dishwasher. Still no boot sound on the CC logic board and the Macintosh TV Board still doesn’t see the hard drive. Anyone know where I can get schematics?

    I think the dishwasher is on must run out I’ll just make sure to wait until it has and then run it through.

    Okay. Will do that! Will jetdry cause an issue? I know you do it without detergent

    I used I saprobic alcohol 99% to clean the board and when I put it into my color classic it had a distorted video but it and boot it now I get this started video still but no hard drive is found. I’ve heard people running it through the dishwasher

    What changes need to be done to the motherboard? Sorry if I'm getting confused. I know I have to cut down the AB from the 550 to fit in the smaller CC case. On a side note does anyone have access to the schematics for the CC and Macintosh TV logic boards? I recapped the Mac TV board and everything was working correctly. Now it won't mount the internal SCSI drive. If I pop the CC Logic Board in it boots fine.

    Are you talking about the physical modification because it’s too wide or additional modifications to the actual circuitry? I get that it is too wide.

    Oh... very cool!!! Thank you. I just recapped my Macintosh TV Logic Board and put it in a CC and I get video, though massively distorted. Need to create a new boot disk that the Mac TV will work on. I will have to go pull the AB from the 550 and see were it lands me!! Thanks again!

    @techknight I'm getting all the resistors, caps, & diodes to do the upgrade. I currently got my hands on 3 Color Classics for dirt cheap! All of them had bad Caps on the logic board. I did my first recapping of one and it boots in every one of the CCs! yay! (Although the startup chime has stopped or is so faint I can barely hear it) Thats for a different thread. Anyway, I have two questions for you. Am I reading that after this mod, the original CC Logic Board will still work or does is this only if you're looking to goto a 575 LB? I'm thinking not, but just checking. My other question is about an AB from a Performa 550. I purchased a 550 on eBay because I got a box of old logic boards that I wanted to recap and check if they worked. One of the logic boards I'm looking to possibly put in a CC is from a Macintosh TV. (Probably the rarest of Logic Boards to find in a random box-O-boards purchased off eBay) However, it arrived with the casing in hundreds of pieces. I tried my CC board and when it didn't work I decided to strip the parts out of the 550 and send the rest for proper recycling. The it dawned on me that the CC logic board wouldn't work on a 550 because its not configured for VGA. Though in pieces, I still have the 550 tube and AB. I'm wondering if I should Mod the 550 AB instead of the CC because of the rareness of the CC. Is it possible to make a 550 AB drive a CC tube? I get that I'd have to cut the AB board down and get clever in fitting it in the CC casing because the "bump out". I'm fairly new to this level of Modding and want to make sure that I don't damage the CC tube or fry a logic board. Any advice? BTW this site is awesome!!!
