    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.

    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...

    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?
