  1. I just ordered a set of caps to service several Color Classic analog boards. There are 23 different caps on this board, so just getting all the right stuff in the cart was tedious. Here's a Digikey cart link to make it quick and easy for anyone else doing the same. https://www.digikey.com/short/zmr2t1 This is for a complete recap, which may be unnecessary. Check out the various guides if you want to trim it down to only likely culprits. Also, the quantities in this cart are to replace caps on one board, with no spares. Most are very cheap, so you might want to get 10 or more of all to have them handy if you plan to to other recapping work in the future. Cheers!

    CC and SE30 damaged pads

    Destroyed a few pads on my CC and SE/30 boards. CC was the first board I tried to re-cap, with my rusty soldering skills and not the best iron. My electronics guru helped reconstruct most of the traces but we couldn't get this last one and I can't tell what it connects to. SE/30 recap went smoothly (I learned from my mistakes with the CC and took it slow) but I broke a pin off UF8 and then killed 4 traces trying to remove it!

    Color Classic Fan

    Can any of you Color Classic owners confirm if the stock fan is 80x25mm and runs at 12V? Also, is the fan 2-wire or 3-wire? Lastly, if there is anything that would impede the easy replacement with a modern 80x25mm fan, please let me know. Thank you!
  4. Hey Guys, I have a color classic that has worked great though the years. Tried to turn it on this week and got nothing... I guess the caps finally went. Opened it up and had a little leakage, cleaned up with Isopropyl and ordered some caps from console5. Caps arrive and I replaced them but it still doesn't power on I started reading all the previous posts here and started checking voltages and traces. What I found out was, the system WILL power up when the board is removed. As soon as I plug in the board the system immediately shuts off. I checked the Analog Board Voltage and have a good 5v and 11.95v. After messing around I was able to get the board to go in and the system stayed on, but i only got a black screen with horizontal lines. After I took the board back out and inspected it I found the Ti 9307XN Chip in the upper right corner by the 2 100 and 47 caps was very HOT!!! Checked the traces around it and could not find anything off. Maybe this is the problem ? I am hoping you guys can help
  5. The quantum hard disk in my color classic died, so I bought a SCSI2SD and was reading some information about it on codesrc.com and there was written that SCSI2SD needs to run on 5V or else the board would break.
  6. Folks.... I need some help with the correct name/nomenclature of some SCSI connectors. I am trying to plug a SCSI CD drive into the back of my Color Classic. Photo sphoto1 shows the SCSI cable connectors on the back of a CD drive. The SCSI connectors are small at about 1 and 5/8th of a inch long. Photo sphoto2 shows the SCSI cable coming from the back of my Color Classic. It is quite wide at about 2 and 1/2 inches. Is the SCSI connector in the back of my CC called a "50 pin Centronics"? What is the name of the SCSI connector on the back of my CD drive? I saw this SCSI adapter on ebay and wondered if it would work: https://www.ebay.com/itm/HPDB50-SCSI-2-Male-to-CN50-SCSI-1-Female-Adapter-CablesOnline-AD-S05/272707095673 What I really want to buy is a cable with the correct head at one end to plug into the back of my CC, and the other end to plug into the back of the CD drive. Can anyone point me to one? Also, I need to buy a terminating resistor (I think) that would plug into the back of the CD drive. But I can't buy one because I do not know what the SCSI connector is called. Help appreciated. Thanks mraroid
  7. I bought the color classic, previous owner said that it's working but when I connected everything and pressed the soft power button on ADB keyboard, nothing happened (the switch on back was turned on). I found on the internet that I should let it attached to the power for a day, it didn't help. I pulled out the logic board and turned the switch at the back on and I heard fan and hard drive spinning. Any ideas how to fix it?
  8. Since my SE/30 Wi-Fi Mod was somewhat successful, I decided to apply a similar technique to my Colour Classic (I’m not a total Mac hoarder, I only have these two!). Here’s the result: (my Colour Classic is a Mystic with a 575 logic board, but this technique should also work on a stock Colour Classic) If you’ve got an SE/30 with a network card, then you’ll know that it is in fact 2 cards connected by a ribbon cable – this made my original Wi-Fi conversion easy as I could just re-arrange things inside the case. However, network cards in the Colour Classic butt against the case, so you’re restricted if you want to attach a Wi-Fi antenna. One solution would be to modify the network card itself – i.e. de-solder the RJ45 jack and replace it with an antenna. However, to me it seemed a travesty to butcher a vintage expansion card. Instead I came up with a non-destructive solution which involved mounting the antenna in the RJ45 port itself: Voila! The idea here is that the Ethernet connection feeds into the mac via a thin cable – and then the Wi-Fi signal feeds back out to the antenna (genius, I know...). I found these thin Ethernet cables on eBay, so I ordered a 1-metre one for just a few dollars: I stripped the wires off one end, and then I removed the plastic from the middle of an RJ45 jack using my Dremel: I crimped the cable back into the jack – but this time feeding the cable downward instead of outward. Then using some Epoxy Putty, I placed the antenna mount inside the jack. You need to work quickly as the epoxy putty sets like a rock in just a few minutes: With some fine sandpaper and a lot of patience, I got it looking pretty clean. A lick of paint: Now for the other end of the cable! The Vonets Wi-Fi card comes with some extra little bits for making your own connection: There are 6 pins on the Wi-Fi module for you to use: I soldered the 4 TX and RX wires from the ethernet cable onto the correct pins. The remaining 2 pins are for 5v power and Ground, so I soldered on another wire for the power. Here’s the finished assembly: I piggy-backed the Wi-Fi module onto the ethernet card using a 15mm M3 screw, nut & spacer: The final problem to solve was how to get power to the Wi-Fi card. I could use the same trick as my SE/30 project, whereby I pulled the power from the Molex drive cable using a splitter – however one nice thing about the Colour Classic is that you can easily slide the motherboard in and out via a single connector, I didn’t want to lose that. I noticed that the LC PDS slot on the motherboard was a bit longer than what the network card required. After a bit of research it turns out that there are 2 LC PDS connectors – a 96-pin connection and a 114-pin connection. I found the pinouts for the LC PDS slot on the Interwebs and lo-and-behold there is a free 5v+ and ground connection in the unused holes. I marked them using a Sharpie: Here’s the ethernet card and Wi-Fi module fully connected: With bated breath, I powered on the Mac expecting fireworks – but everything worked perfectly! The link light came on the Ethernet card, and you can see inside from the blue lights that the Wi-Fi card has power! Obligatory IP address screenshot Here’s my 2 Macs with their Wi-Fi Antennae
  9. Hi folks..... I saw this card on ebay and i am not sure what it does. Can anyone give me a heads up? Here is a link to the card. :The card is made by Asante. https://www.ebay.com/itm/Apple-Mac-Color-Classic-PDS-Ethernet-Card-Math-Co-Processor-LC-Performa/112629676565 If the above link is broken, you can search for item number 112629676565 I have a Farallon network card in my Color Classic. I have a math co processor installed on the main board. I do not know what this card will do. Thoughts? Thanks mraroid

    Ethernet on my CC

    My Color Classic is repaired, and I have loaded 7.1 on it with Update 3. Now I want to install either MacTCP or OT and setup the ethernet. I have an Asante MCLC Twisted Pair card installed. When I plug in a cable, it lights up. I have tried unsuccessfully to get this working. First I installed the Asante Ethernet Installer 5.2.9, that installed MacTCP 1.1.1, but it would not connect to my LocalTalk network via EtherTalk after that installation. Serial LocalTalk works fine. I searched the net a bit and found a walkthrough for installing ethernet in an SE/30 running 7.0.1 or 7.1. Using that guide, I installed the Network Software Installer, followed by MacTCP 2.0.6 and the patch to 2.1. Still, I cannot get any communication to work over ethernet. Does anyone have any advice for me? Did I mess things up when I installed the Asante stuff first before I installed the Network Software Installed and the MacTCP 2? Should I be using different versions of this stuff?

    Dead Macintosh CC :(

    I posted a while back about a Macintosh CC that came into my posession with serious corrosion. Someone gifted me a board that needed recapping, and I finally just got it back from maccaps. I plugged it into the machine, heard a slight whine noise, and got absolutely nothing when turning it on. No fan, no chimes, no nothing. When I take out the board and turn on the machine, the fan does turn on. Does this mean there's a short in the board somewhere? The guy from maccaps assured me that it was working when he sent it back. What are the next steps? Thanks! EDIT: There is currently no PRAM battery as I am waiting for one to come in the mail. I'm not sure if that's a major factor?
  12. I have a Macintosh Color Classic that I just restored and I am attempting to create a System 7 boot drive for it. I have a "3M High Density 2.0 MB" floppy that I am writing an img file to using the dd command on Linux. I either get the error that there is no space left on the disk after a few minutes of whirring, or that the end of the device was reached. That can't be right? I feel like a 2.0 MB floppy is big enough for System 7. Anyways, when trying to insert it into may machine, some painful whirring noises occur and it eventually gets auto-ejected. Any help would be really great! I'm not sure what to do from here except to buy a pre-installed floppy online.

    CC (re-capped) Stopped Booting

    Hello all, The short version: The CC (re-capped) no longer boots. I seek guidance. The long version: I booted my Colour Classic earlier today after about 8 months of non-use and I ran into a series of issues. Let me start by saying that the CC has an LC 550 logic board. Both the logic board and the analogue board (integrated power supply) were fully recapped around two years ago (ceramics, tants, and electrolytics where necessary) with ONE exception. I had the wrong sized 330uf 400v, so had to resit the original (see photo). Nevertheless, the CC operated perfectly well after all that. Today is a different story. When I first booted the computer, I noticed that the screen was continually dimming and brightening, almost alongside the speed at which the hard drive was spinning. I initially thought there was an issue with the screen (flyback?). However, after rebooting twice and then trying a third time, the CC stopped booting altogether. When I flick the power switch, I hear the screen get a bit of juice, but soft power boot with the keyboard (tried multiple keyboards and different ADB ports) results in absolute silence - there's no indication whatsoever that a boot was attempted. So, now I'm wondering if it's a power issue. If so, what steps should I take to start discovering the culprit? Could it be that ONE remaining capacitor that needs changing (something I intend to do now anyway)? Might the fuse be blown as well? What's the rating on that? Thanks in advance.

    Mac Color Classic - No Video

    Hi everyone, I'm new to the forums, but I was wondering if anyone could me troubleshoot my Mac Color Classic (stock, no upgrades like Mystic or Takky). I opened the computer and replaced the original 80MB HDD with a 2.1GB disk. Before, the screen worked and it showed the blinking disk icon, but now even though the computer turns on and makes the startup chime, the screen is entirely dark. I wouldn't be surprised if this was a cable I knocked loose or forgot to reconnect when I was removing the analogue board, but so far, I haven't been able to find anything out of place. Here's what I know: The screen still builds up a charge on the outside, which leads me to believe that the issue lies with the electron gun towards the back. The computer sounds like it's booting fine, and I think I can hear the HDD being accessed. I couldn't find any unconnected cables after checking three times. All the wires leading to the video board appear to still be firmly attached to the analogue board. The metal shielding covering the edge connector in the front corner of the analogue board is missing, though the computer appears to have worked fine without it. There's electrical continuity with the ground wire from the video board all the way to the ground pin on the cord. I was about to try removing the video board from the CRT to have a look, but I figured I'd ask here first before I make any more problems for myself. Thanks in advance for any suggestions.
  15. Hi! I’m totally new to this forum and new to the vintage Mac scene, but I love all things retro and when someone gave me a Macintosh color classic to try to fix, I was super excited! The machine turns on (I hear the fan) and emits three monotone beeps. Not the chimes of death, but something I can’t figure out. I busted out the logic board, and wow. There was some serious corrosion. I tried to clean it up with some isopropyl alcohol and cotton balls, but some resistors totally fell off and I can see connectors that are completely worn through. I’ve attached some photos. What should I do? I only see one really leaky cap. Should I try dishwashing it? I’ve heard of this method but I don’t know how to go about I to without a. ruining my dishwasher or b. ruining the board. Any suggestions would be very welcome! Thanks, and glad to be a part of this community!
  16. Hey folks. I remember reading about something similar to this some time ago. But I didn't pay that much attention to it as I wasn't really into CCs back then. Now I am though. I recently picked up a nice looking original CC. The seller advertised it as non working/for parts only and as it turns out, it boots up just fine. (apparently he had completely forgotten about soft power...) So that's good. What isn't though is this: NB: The flag in the top right section of the screen is supposed to be the French flag. Blue, White and Red. It's definitely not supposed to be green, white and blue. Interesting fact: when you give it a little whack on the side, the display becomes wavy for a couple of seconds then it goes back to the weird acid trip colours.... I know the last owner has been tinkering with its insides lately, so he could have messed things up a bit. But IIRC this problem can be caused by cold solder joints on the A/B or on the neck board PCB or simply by a completely shot CRT. That would suck. Or could it be just caps? I really doubt it though. Any clues to what I should look into first? Thanks in advance! Cheers, BGE
  17. I retrieved a Color Classic from a stack of discarded Macs some time ago (~2002-ish) and in the same stack, grabbed an LC 575 (which turned out to have a cracked CRT) and a box of miscellaneous parts that included a full (non LC) 68040. A year or so later, I did the VGA mod to the analog board, found a 32 MB SIMM that worked, swapped in a 1.2 GB drive and installed some system(probably 7.5.3 - that's what I installed on everything back then). Then I put it on a shelf and it hasn't moved since. Around the same time I got that CC, I found a couple SE/30s. Both had dead drives, but I found replacements and cleaned them up. One I donated to a shop my father used to work at (they used several old Macs for running their CnC machinery) as a spare. I think they lost it in a fire a bit after that. I still have the other, which, like the Mystic-ized CC has sat on a shelf since that time. I think I've got 32 MB in there as well, and I later found an Asante MacCon ethernet card that I have yet to install on it. So, all that in mind, if you had to choose to keep one of these (and only one, because justifying both to the lady of the house may not be possible), which would you keep?

    Color Classic Mystic Upgrade Help

    Hi everyone - I recently was fortunate enough to come across an LC575 board (Mystic) for my Color Classic which the original board had become extremely corroded. I was given the Color Classic a few years ago from someone who did not remove the battery and it caused a pretty large mess. I was able to clean out the system and this morning put the LC575 board in. It appears that the current drive has System 7.1 installed and needs to be updated, as I am getting the following message on startup: This startup disk will not work on this Macintosh model. Use the latest installer to update this disk for this model. (System 7.1 does not work on this model; you need a newer version that does.) I have a usb floppy available on a PC. Can I download a startup disk / tools disk or upgrade set? I also have a Power Mac 7100 running System 7.5 with a CD-Rom drive. Thanks very much for the support!
  19. Hi... I am looking for some software that might give me the temperature of my CPU, the logic board, hard drive, or anything close to that. I am running 7.6 and 8.1 in my Color Classic . I have been unable to find anything. Suggestions welcome. Thanks mraroid
  20. Hi.... I had been using a CD reader with my Color Classic. But I needed a CD drive that I could use to burn CDs from my Color Classic. So I bought a external Smart and Friendly Imation CD-R 8 X 20 CD drive. I used it when I upgraded my Color Classic to 8.1. The install went perfect. But after the install, I found that none of the CDs I put into the drive would ever appear on my desktop. This included the apple branded 8.1 CD I had used to install my OS. So I put the 8.1 CD back in the CD drive, rebooted with the "C" key depressed. It booted to my CD. After that, I ejected the apple 8.1 CD, and stuck in one of my own CDs. When I do that, it will appear on my desktop and I can used it. But I can only do that a few times, then it quits. I tried to install Toast 4.1.3. When I launched Toast I get an error message that says: "An unknown Driver is installed for the CD recorder at SCSI bus 0 ID 4. If you run into problems please remember to disable the driver next time." I formatted my CF card before the install of 8.1 and I had not installed any other software. So the only CD driver that could be on my color classic is one that 8.1 installed. I do not know how to find that driver and remove it or disable it. Could this be why I have having issues with this CD unit? Originally it was on ID 3. I changed it to ID 4 and had the same issue. I have a terminating resistor plugged into the back of this drive and I believe it is good. Anyone have a manual for this CD drive? I found nothing on the internet. Any suggestions welcome. Thanks mraroid
  21. I would like to clean (at least the underside) of the analog board of my Color Classic. I am unsure of the correct chemicals to use. ​I am in Ecuador, so name brand cleaners are probably not available to me. I have access to distilled water. I can buy common chemicals (vinegar?) and some common types of cleaning liquids. I searched the forums here and found a *huge* variety of things that people use. Perhaps someone could post maybe the top three things to try? I was thinking distilled water and a soft toothbrush to start. I have access to isopropyl alcohol but it is only 70% (it was over 90% in the USA). I have access to vinegar. We have a "409" knock off here in Ecuador. On another web site, I saw a suggestion of using heat gun (I have a good one) to re flow the solder on old apple logic and analog boards. I don't think i want to do that. But cleaning - yea, I am up for it. Maybe no liquid but just a soft brush? Suggestions welcome. Thanks jack - mraroid
  22. I was reading some very old posts on this forum. I came across this: **************** An interesting side note here: I put my Mac TV logic board in the CC and not only did it boot up without any special enablers, the screen also had a default resolution of 640x480 without any software or hardware hacks to the analogue board. This tells me that the logic board has all the necessary output to send the proper signal to the analogue board. This is likely due to the fact that the Mac TV was designed to output 640x480 TV resolution, but I have no idea what aspect of the logic board differs to allow it. It also makes me wonder if the CC wasn't originally considered for a Compact Mac TV variant. This would explain why the CC was designed with stereo audio hardware in place (Interestingly none of the pre-580 models have stereo input, except via PDS slots). The reason why the LC 520 came into existence in the first place was because Sculley had bad eyes and took one look at the CC and declared they needed a bigger all-in-one: never mind the Mac had sold millions without one in the first place. ***************************** That almost sounds like a very safe way to have 640 X 480 in a Color Classic. But the Mac TV uses a 68030 processor. I like a mod where I can upgrade to a 68040 better. Has any one else tried this? Here is a link to Low End Mac re the Mac TV: http://lowendmac.com/1993/mac-tv/ Here is a link to the non USA release of the LC 520: http://lowendmac.com/1993/mac-lc-520-performa-520/ another link on Mac TV: http://appletothecore.me/files/macintosh_tv.php I see a non working Mac TV on ebay right now. Probably overpriced at $500 and the seller (with bad feedback) willl not ship but will deliver to NY, NY: http://www.ebay.com/itm/RARE-Apple-Mac-Macintosh-TV-TELEVISION-COMPUTER-System-Only-Parts-Repair-/322528960975?hash=item4b183961cf:g:-vQAAOSwblZZJuc8 I am in Ecuador, and postage would be too much. But I would like to buy the logic board for this just to play with it.... mraroid
  23. Hello... I have 7.6 installed on my Color Classic. I have a Farallon network card plugged into the Color Classic. I have installed the Farallon software. I have installed TCP/IP V 1.1.1 I have Netscape 2. something installed. When I go to the TCP/IP control panel, I am set up for ethernet, and DHCP. However none of the other fields are filled in. Can I go to a windows box and do some kind of command to find out my gateway or other information? With a ethernet cable plugged into my router and the color classic, I can see a green light come on in my router when I boot the color classic. How ever the green light on the back of the ethernet card is not on (and I can not connect to the internet). I think I am close, but no cigar. Can an one give me some additional information? Thanks mraroid
