Both of the boards in the photo (link below) came out of Color Classics, and neither of the CCs works. Obviously, I want to figure out what they are before I try them again. Can anyonbe help me out here and tell me what these are? I'm pretty sure the greener one is a stock CC board. But what of the brown one? I've supplied the serials that were on the boards.

Need a few Sherlocks, please.

The green one is a stock CC motherboard
The brown one is an LC520 or 550 board

Actually, IIRC the 520 MLB is the same as that of a CC. The brown one is probably from a 550, functionally the same as a CC II.

So we could say jyowell's boards are CC and CC II.

Help!

Can anyone tell me if my machine (a PPC 8600 beige running on a Crescendo G5 400mhz upgrade processor) has a graphics card that will allow 1024 into 768 or above resolution in thousands of colors on OS X (I'm running OS X on this machine with the help of XPOSTFACT 3.1.a1)?
If it won't, does anyone have an upgrade graphics card for my machine, that will allow higher resolutions, and that they are willing to trade? I have monitors and hardware of a ppc 7300 and a performa 6100 (I think) and quite a bit of software (MS word 5.1, 2001, etc). You can reply to me here or directly to my email .
I apologize in advance if I'm sending this post to the wrong place!
Thanks!

I'd disagree that the CC and

I'd disagree that the CC and LC520 boards are the same. The CC used two 30 pin SIMMs while the 520 like the 550 used one 72 pin SIMM.

CC & 520

AND the 520 was a 25MHz bus while the CC was 16. The 550 was 33Mhz and shares the same part number as that of the CC II also a 33MHz (then again I don't believe there were any CC IIs -- haven't you heard?) Smile So therein lies the confusion. The 550 has a stereo sound output, so if the connector has three wires going into it instead of two you'll know which is which.

Color Classic II?

So assuming I have a CC II board, does it follow that any CC case you put that board in is automatically a "CC II," or were there other enhancements to the case that made these machines CC IIs?

LOL!

Well, what you most likely have is a 550 logic board given how VERY rare the CC II was (if it even existed ). The big "IF" is whether or not there was anything else that set them apart. We know for sure at the very least there would be a CC II badge: Stuart Bell allegedly has one (although he may have fabricated it to impress the boys down at the pub *I'm kidding Stuart*). Aside from that until someone actually produces a CC II, the Apple specs would indicate there is absolutely no differences in the remaining hardware. Since the specs indicate that the CC II and LC 550 logic board share the same part number, technically you have a CC II without the badge. However, I would guarantee that there are modifications to the Analogue board, if nothing else, as Apple continually upgraded their parts as "real-world" use exposed their flaws, though they may have been introduced in the late model CCs as well and can't really count as differences. And, in particular, since the CC II was only sold outside the US, it would have probably had a 240v power supply (but in that since, it would be the same as any foreign original CC), though I think Japan and Canada use 120v too possibly rendering this an altogether moot issue. As for any substantial operating changes, aside from my theoretical stereo speaker addition, I doubt it. But until someone produces a real CC II, we won't know for sure (so lay off the CC II claim until that day comes). If the badge and logic board are ultimately proven to be the only differences (and there are 120v versions), then you still won't have a CC II until you get a badge. But if that's the case, I won't really care anymore -- HA! I'd rather it just read Color "Classic" on the badge the way the 128k just reads "Macintosh" (and soup it up inside!).

Chip ID & Correction.

We've been going about this the wrong way! If it's a Motorola 68030FE33B chip, then it's a 550: a 68030 chip with a 33Mhz bus. If it's a 68030FE16B it's a Color Classic, if it's a 68030FE25B it's a 520. I'm pretty sure this method will work, but not certain. Given that your serial number does not have the word "Hook" next to it (the 520's code name), I'm inclined to believe it is a 550. Note this image of a 520 logic board has it: http://www.micromac.com/macpixpages/a_mac_lc_520.html, whereas this image of the 550, doesn't and is closer to your logic board: http://www.micromac.com/graphics/LB_P550-sml.JPG It also has the red tape on one of the sound ports, though not necessarily a determining factor, nor is the color of the bread board as both could change during the production run.

Now an appology if I am wrong. There is conflciting information around the web as to whether the 520 was in fact stereo or not. Now I'm not so sure. It may or may not have been stereo. The Mac TV was a variant of the 520 and was stereo, so it is likely the 520 was too. Anyone with an actual 520 could easily confirm this, both that the logic board was stereo and the analogue board output true stereo to the speakers.

Re:Chip ID & Correction

Identifying a CC, 520 & 550 by the speed rating on the processor isn't going to work. Apple often overclocked 030 processors. I have a 520 motherboard that has an overclocked MC68030FE16B. Looking for HOOK is a possibility but I wonder if all 520s had it or if the early 550s had it. Probably if you can get to run then check the speed and if you can't then it's not too critical.

Ah, I knew that was too easy to work across the board. Probably there never was a FE25B chip then. If he has a board without "Hook" on it, then he most likely has a 550, though even that's not definite if the 520 boards were made in different factories, "Hook" may have been left off of them as well. There are part numbers on these boards by the copyright dates which may further help ID them My Mac TV has 820-0357-03. The Color Classic has 820-0367-C.

What is your part number on your 520 lb? Also, can you confirm for me that your 520 outputs stereo sound from the logicboard (not just dual mono)? I'm pretty sure it does, just want to confirm.

If his lb part number doesn't match any of these, then that's even stronger evidence he has a 550.

I discovered that I had anoth

I discovered that I had another 520 LB stashed away. This one has a 25mhz processor but is otherwise the same as the other board. Both are part # 820-0368-A.

I'm not sur how to check whether the board outputs stereo or mono. I only have the LBs and the only case I can put it in is a CC.

I'm not even that close! I have CCs with 'Colour Classic', "Color Classic' and 'Performa 250' badges, but not even a CCII or P275 badge, never mind a complete CCII! Sad
