Does anyone have a pinout of the logic board to analog board connector on the Classic II?

Thanks everyone. Good to know about the lack of audio circuitry on the analog board. Will check out the speaker! (I tried the Classic logic board in the Classic II case and no sound either, so am sure it's not the logic board).

Can you post some pics of the connectors? I've had varying success to be honest. Some require an adapter and terminator and some just don't seem to work. Where are you based?

I have a Mac Classic II that has no sound. I recapped the logic board but no luck. However, I tried the board in my Mac Classic and the sound came straight on! My question is, does the analog board have anything to do with generating sound (is it an amp)? And if so, is it likely to be the caps...

You should be able to just put the correct details for your network into the TCP/IP control panel and then it should just work. I've found DHCP a bit flakey, so it's best to set up the details manually. I haven't tried this myself yet, but this looks promising for browsing modern sites on older...

I tried a load more disks and it seems I was just testing initially with a couple of dodgy disks. Both drives are working fine now, thanks to everyone who helped!

Just to close this out, I got a 40Mhz one from a seller in the UK and it works perfectly. Seems there are lots of fakes from China on ebay. Seems mad considering how little they must make!

Good shout. I'll take a look. Thanks!

I have two SE/30s and recently tried the floppy drive in one and found it throwing up the "This disk is unreadable" error, and then fails to initalise any disks I have. I took the drive out, re-greased the metal and cleaned the heads with IPA, but no luck. I then took the floppy from my other...

This really is fantastic. I've done my own Mac Classic to iPad screen/Intel NUC conversion which I'll write up at some point but without all of your awesome attention to detail with the CRT glass, floppy SD (!) and original ports for the keyboard/mouse. Well done! The only issue I've found...

I echo the above RealityStorm. A brilliant blog!

I got one of these recently and it worked perfectly: https://www.ebay.co.uk/itm/Apple-Macintosh-256KB-68-pin-VRAM-Video-Memory-SIMM-670-0269-LC-LCII-LCIII-80ns/121956009009?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

Please see attached. Sorry, my phone camera can't seem to focus on all three. The middle and right chips where from one seller, and the one of the left was from another.

Thank you everyone. The 3rd chip came and didn't work either. I might give up, or look for a better source on eBay.  Does adding an FPU to the Color Classic actually speed up much (JPG decoding in web browsers for instance)?

Much appreciated, that's a great offer. I'll DM you if I decide it's worth it. I know it probably wouldn't help performance much, but thought I'd try it out of curiosity as it was only a few quid. I presume these chips are just taken from e-waste, seems unlikely they'd try and fake them at that...

I found the attached pic somewhere on the net and installed the chip in the same orientation. I can't be sure the chips are ok, but have no other way of testing them unfortunately. I have one more on it's way to test, so maybe third time lucky. The source is Chinese sellers on eBay selling them...

I recently purchased a 16Mhz 68882 to fit in my Color Classic. Once installed though, the machine doesn't boot. Power comes on, but the screen is black and the hard disk doesn't boot. I got hold of another 68882 chip, but that does the same thing. Has anyone seen a similar issue?

Thank you all so much for this. It makes a lot of sense. I don't have other Mac's for Appletalk/Ethertalk, so have been using MacTCP and Fetch to pull files from my internal FTP server without a problem and this has worked fine on 7.5. Will try 7.1 and see if I can get the same working. I'm...

Hi everyone, Am new here. I've just picked up the compact Mac bug after using a couple as a kid and this month have picked up a Mac Classic with 4MB RAM running System 7.0 and a Mac Color Classic with 10MB RAM running System 7.5. I'd like to do a fresh install of the OS and was wondering what...
