Curious, what reference/guides are you using for the stereo mod? I found the following awhile back, ordered a TDA7052A Philips amp chip, but never went any further. https://web.archive.org/web/20090429222614/http://www.stuartbell.dsl.pipex.com:80/PowerCC/CompendS.html

Following this thread makes this come to mind: :)

Power Macintosh 4400/200 MacBench 4.0 test results. Spoiler, more L2 cache is generally better, but doesn’t hold a candle to G3 upgrades. Mac OS 8.6 VM off Appletalk off 160GB PATA HD Sonnet G3 400/1MB L2 cache slot processor upgrade used for last test

Clearly, you have angered the PowerBook gods somehow and must use Windows Me exclusively for a week to atone. ….I got nothing 😕

Glass half full: The florescent backlight is working! Has the logic board been recapped? Getting a startup chime? HD activity noises? I guess you’ve double checked at the connections and played with brightness and contrast?

The solution is clear, multiple Color Classics, one to leave stock, one for Method #1, one for Method #3! 🤪

Power Macintosh 7300/200 MacBench 4.0 test results. Spoiler, more L2 cache is generally better, but doesn’t hold a candle to G3 upgrades. Mac OS 8.6 VM off Appletalk off 64GB SSD on Sonnet 133 PATA PCI Sonnet G3 450/1MB processor upgrade (with no Logic board cache module installed) used for...

The goal for this resource article is to document identification and reference information on the various L2 cache modules for Power Macintoshes and clones. While at a quick glance many of these L2 cache DIMMs look similar there are different pin (edge connector) groupings that key the 160 pin...

No, no, no! ….Instant Pot ;)

This is totally right for caps, but I think I read somewhere that there is more soldered on VRAM on the LC 550 board than the CC II board. Its not exactly the same. Trivia…

Alternatively you could use these too: 3.3µF - 35V - SMT - MLCC - 810-C3216X7R1V335M6A (Mouser P/N) They are “Multilayer Ceramic Capacitors“ vs. the Tantalums above. I used them when I recapped my Duo 230 LCD, they‘re smaller, arguably fit better:

When I recapped my PowerBook 100 I used these for the LCD: 3.3µF - 35V - SMT - Size B - 581-TAJB335K035SNJ (Mouser P/N)

Yes, but the EtherMac Printer Adapter is for getting a single LocalTalk device connected to Ethernet. I have the very similar EtherMac PowerBook Adapter. Lots of info here: https://web.archive.org/web/19980111201303/http://www.farallon.com/support/faqs/en/pbafaq.html On neat thing with these...

I have this Farallon adapter, since it has a single PhoneNet connector it just goes at one end of PhoneNet LocalTalk daisy chain network, you don't need a PhoneNet adapter for it. Ethernet switch <- Ethernet cable -> Farallon adapter <- phone cable -> PhoneNet adapter to old Mac <- phone cable...

This is just a physical media bridge for the AppleTalk network protocol, LocalTalk <-> Ethernet. You would need a MacIP Gateway (software or device with both AppleTalk and TCP/IP plus encapsulation code) and MacIP client software to be able to get Mac with only AppleTalk networking connected to...

I would be so down for one of these!

The bus and processor speed are set via a jumper block on the motherboard, some info on this here: http://oldcomputer.info/apple/PowerG3/index.htm

Something like this does seems like it could be very useful for owners of LC/Perfoma 520/550/575! I recently ran into this myself in trying to figure out how to connect up a BlueSCSI to my LC575 in place of the internal HD. I have a short 50 pin extension on order but its going to be a pain to...
