    Mac Plus and Mac SE/30 (busted)

    +500mhz CPU clock boost, totally worth it /j jokes aside those are nice replacements. while i prefer tantalums i do use electrolytics or anything that still works, mainly from scrap boards. it's a good form of reusing electronic components from otherwise faulty systems, but i don't reuse caps...

    IIsi Randomly Dying

    make sure you've put the right caps in the right spots, sometimes substituting other values can cause problems. and yeah i'd check the daughterboard, that has a couple of SMD caps that should be replaced. the IIsi notoriously has a very failure prone PSU and unfortunately the caps on those seem...

    i already have a lot of SCA disks around from when my high school tech teacher was getting rid of them and i'd like to put them to good use. sure they take up more power, they scream bloody murder, and they run hotter than the sun (and i already know this)... but i have a lot of them and i need...

    SE/30 Battery Bomb Advice

    only reason i have one is because a guy i knew on discord had to clear out his inventory and he had an SE/30 that i bought for the cost of shipping, complete with a rasterops colorboard 264. thats never gonna happen again because it simply won't happen more than once in this day and age.

    PowerMac 6100, Performa 450 , Mac IIsi

    i am a novice IIsi witch, i overpaid for an untested and nonworking unit from a local computer shop but i managed to get her working, and even went out of my way to upgrade the onboard RAM because i am dedicated enough to do stupid things.

    SE/30 Battery Bomb Advice

    seems like theres also some severe cap leakage; this is definitely something you'd want to use for a reloaded board. the muxes are 100% going to be fried, you'll have to replace them. PALs seem to be fine, video ROM may or may not work, the 68030 also might not work, ADB chip is likely shot, but...

    Katheryn's Macintosh SE/30 saga

    which one would be the video PAL? and what would i replace it with?

    macintosh IIsi 4MB onboard RAM upgrade

    ahhhhhhh, i see. thanks for clarifying. kinda knew it wouldn't make a difference but i wasn't sure.

    Katheryn's Macintosh SE/30 saga

    ah, fair. that would be lovely for sure though.

    PowerBook 540c screen issue

    yeah so its likely active matrix, my bad. that cable on ebay unfortunately won't work.

    what's a good power supply replacement for a 475?

    its TINY! i love it. definitely seems like the better option for these especially considering these pizza box macs don't take much power, and they don't use soft power. i'll definitely buy one.

    IIsi fault ...

    yeah, i'm sure it does... lol. they're definitely cheaper than the half AA batteries, and they don't last as long. but they're more convenient when you do need to replace the battery for sure.

    PowerBook 540c screen issue

    if you have a passive matrix display, yes. if yours is active matrix, no. the easiest way to tell is if your screen has more severe ghosting iirc, passive matrix refreshes slower and has a ghosting effect if you move something on screen (could be anything), active matrix is like what most LCD...

    Katheryn's Macintosh SE/30 saga

    yeaaaaahhhh.... i hope i didn't screw up the video PAL. speaking of video... has anyone recreated the micron xceed card stuff? i'd love to have one because the SE/30 deserves better than 512x342 at 1 bit color...

    Katheryn's Macintosh SE/30 saga

    i think for one thing my attempt at fixing the original board last year had done some damage to the chips because i know the solder paste i used then was crap... thankfully i've already watched some replacement chips on ebay so i'll buy those when i have a more disposable budget.. lol. not sure...

    PowerBook 540c screen issue

    speaking of that... would it be possible to swap the screen on a 520 with a color active matrix screen?

    IIsi onboard ram replacement

    i do have a nubus adapter, though i'm not sure which card to buy. is there anything with a video chipset and ethernet by any chance?

    Interware Booster CV 40 - Doesn't work on SE/30

    i figured. just thought i'd mention that anyway >_>

    macintosh IIsi 4MB onboard RAM upgrade

    i'm doing a reloaded build and i think i may have screwed something up kinda badly since i don't get video anymore. i'll have to fix it when i have the time to, but now that i have the microscope i can easily see what i'm doing, whereas i wasn't really able to see everything earlier.
