    PPC Macintosh L2 Cache Modules - D - PM 7300 L2 Cache Benchmarks

    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...

    PPC Macintosh L2 Cache Modules

    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...

    Recapping a Performa 550 - Same as Color Classic II main board?

    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…

    PowerBook 100 screen recap

    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:

    Interesting solution for LocalTalk to Ethernet bridge

    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...

    Interesting solution for LocalTalk to Ethernet bridge

    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...

    Interesting solution for LocalTalk to Ethernet bridge

    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...

    3.5" Hard Drive 50-pin SCSI Reference Design

    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...

    Cleaning solutions for ultrasonic cleaning of electronics?

    In the States here, I couldn't easily find Branson EC a year ago when I was setting up my VEVOR 30L Ultrasonic Cleaner (although perhaps I didn't do such a good job searching...). I ended up going with this which was available on Amazon: Elmasonic 800 0102 Elma TEC Clean A1 Ultrasonic Cleaner...

    What are your vintage grail items?

    I would like to find a SE SuperDrive, SE/30, and/or a Classic/Classic2. It’s a design thing for me too. Mostly. And I’m totally with you on the trashcan Mac Pro, always made me scratch my head but it’s undeniably interesting and unique.

    Power Macintosh 475

    I also wonder if the Apple version can actually do 3x or 4x bus multipliers if some resistors are moved around. I‘m pretty sure I read somewhere that DayStar built the Apple one for them so the two boards are likely very similar...

    Power Macintosh 475

    Awesome! I hope to join you in this one day, with a Power Macintosh 605/100 in my case! This is one of the many project that I have on deck held up by something or another. My problem here is while I have the DayStar 100MHz version (yay!) and it lets you set the bus clock multiplier to 3x or 4x...
