    PowerBook 540c screen issue

    ahhhh. didn't know they made active matrix models before the 5300. the cable could be the issue given the line pattern, and the CCFL bulb is probably on its last legs with the flickering (or the inverter is faulty).

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

    yeahhh i think you'd need a 32 bit clean ROM. IIci and IIsi are 32 bit clean, whereas the SE/30 is not along with the macintosh IIx and IIcx it was designed from. either way it may be routed differently so the card may not work regardless of your ROM on an SE/30.

    Mac Plus and Mac SE/30 (busted)

    i personally go for tantalums whenever possible. recapped a IIsi using tantalums from a couple of scrap boards and it works perfectly. i try to salvage as much as i can unless i don't have something available, but stuff thats plagued with faulty caps from the 2000s i get rid of on sight if i...

    has anyone tried to upgrade the L2 cache or the CPU on a sonnet crescendo L2 card? i have an old G4 7400 card sitting around, plus a crazy idea... but i guess i would only just be able to get 1MB of L2 from 512KB given my equipments capabilities...

    yeah, really no point in doing this unless you wanna take the time and effort to do it... lol. honestly it feels more responsive but thats probably just the 25mhz overclock and a nubus riser card (which also gives you an FPU) i got from a friend. now to find a good sca 80 pin scsi to 50 pin...

    heard that from someone on tinkerdifferent who did the same thing, kinda assumed it would since the IIsi's onboard RAM is also used by the video chip on the system so the CPU and GPU are constantly accessing the same RAM area if something is running on the onboard RAM... and more stuff is being...

    Micromac site is live - are they?

    i would not put any of your information on that site, i think it's only kept up for preservation purposes, but you do risk identity theft (especially since it's not HTTPS), and the company is long gone.

    Katheryn's Macintosh SE/30 saga

    just bought a microscope from amazon and i'm putting this on hold until it arrives, and until i have the courage to fix whatever i broke. meanwhile i have resources to build some 1MB SIMMs, i think. still have 22 chips left over from a tube i bought from ebay to use on my iisi's motherboard, and...

    $37 USB Microscope on Amazon..Great results!

    should definitely get one of these. it would help a lot especially with the pain and suffering i'm going through with a certain project of mine. edit: just bought one and my wallet's dead.

    did an onboard RAM upgrade on my IIsi not too long ago, swapped out the 128KB chips for 512KB chips and now my IIsi has 4MB of 70ns onboard memory. yes it will likely make it slower, but i felt like it, also i know i am not the first one to do this lol

    did that, still noisy. like something's grinding, even though the gears are still perfectly fine. i think the motor is worn out??

    Katheryn's Macintosh SE/30 saga

    no chime, and no display... idk what i did, all i had done was replace 80% of the muxes. i might see what's going on with it another day, i really need to focus on life right now... :/
