    i know this could be a very divisive subject among a lot of vintage laptop enthusiasts as it takes away a good amount of the charm from a vintage laptop, but what do yall think of the idea of modern LCD replacements for vintage laptops, especially those whose screens have deteriorated or are just broken?

    shouldn't be divisive. working screen > bad screen. i support modern replacement efforts for lcd panels.

    Working screen > bad screen, but original screen > modern screen.
    If there was a laptop I really loved for the form factor, and my only option for using it was a modern reproduction screen, I'd take it. But the original screen's appearance/quality is a huge part of the appeal for me - be it passive matrix or active.

    If you can find a panel in the right size and resolution, and work out how to interface it, I think it's a great idea. Though I suspect that could be a big "if" unless you're willing to hack up the bezel to accommodate a display of a different size and aspect ratio - a lot of the mono PowerBooks whose displays suffer the most are 16:10 640x400, which is a bit of an oddball.

    got a powermac 6400 off of ebay, can't wait for it to arrive. also getting a radeon 7000 to flash to a mac ROM and will transfer my g3 upgrade from my 6360 over. its gonna be a killer system 7 machine

    of course you can. the flashed sil3112s work on any pci powermac.

    Congrats! I recommend Zone 6400 (https://web.archive.org/web/20220522165815/http://zone6400.com/) for resources.
    I've had a lot of trouble getting an ATI Rage 128 to work on my 6500 due to conflicting extensions, and clashes on the PCI bus with the ATI Rage II on the motherboard (see Gazelle PCI hack thread on 68kmla).
    Given that the 6400 doesn't have on-board ATI graphics, you may have better luck :)

    yeah, a few people said that the 6400 was better for upgrades. i still can't wait for it to get here, ive lowkey wanted one since i was a kid because they looked cool (and, unlike a good chunk of performas like the 5200 and 6200), are actually cool.

    i have a couple of pre-balled 1GHz 7455A chips and i'm thinking i want to get a 2002 eMac and a spare board, and swap one in. also i have a couple of dead G4 cards and the 2002 eMacs and iMac G4s have provisions for L3 cache. pretty sure you can tell what this girl is thinking about doing
    alectrona2988
    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...

    The Sonnet G3 cards of various types (be it the NuBus, PCI or L2 cards) do work with the G4 swapped in, with the Sonnet extension then correctly detecting it as a "Sonnet G4" card. You do however need to lower the core voltage (750s generally run above 2V, the 7400 needs 1.8V), and just to be sure: You can only use the 7400 due to the cache voltage, the 7410 wouldn't work.

    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

    Nee to have a look if I have any assembled, if not I still have loads of blank PCB's and components, drop me a PM :)

    why an sca adapter over a nice SD adapter? those disks are rather loud and hot...

    actually i ripped one out of my iisi. silly thing!

    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 to put them to use.

    has anyone tried to use a manual inject floppy drive on a mac that takes auto drives?

    Puts a little bit of silicone grease in the gearbox? Might help.
    alectrona2988
    alectrona2988
    did that, still noisy. like something's grinding, even though the gears are still perfectly fine. i think the motor is worn out??

    If it is the actual motor it might be contamination. Have you put some machine oil on the motor bearings? Can't remember if you can get to them.

    Does it make the noise when you run the motor not inside the floppy drive? Unscrew it and lift it out, but leave it plugged in. It should run continuously when you eject I think.

    So I own a IIsi now. Power supply is unsurprisingly dead, and I am also interested in overclocking. How far could one get with clock chipping on a IIsi? Anyone ever got to 30MHz before?

    I think I've seen posts of people going up to 27.5mhz and starting to have problems. Mine is overclocked to 25mhz with no problems. I have never read of people having problems at 25mhz, though I'm sure it has happened. Generally the stock 20mhz CPUs don't have a problem at 25mhz.

    It might not be the CPU that is struggling at 27.5 and above, it is more likely the software timings for hardware. If you speed up an early Mac that is not designed for it, you break timings for critical hardware.

    I'm going for 25; I just ordered a 50mhz oscillator.
    alectrona2988
    Does anyone here have BGA soldering/reballing skills? Want to have a PowerPC G4/7400 transplanted onto an old G3/233 processor card from a Rev B iMac.
    alectrona2988
    We can rebuild her. We have the technology. We can make her better than she was. Better, stronger??? faster... I guess? God, this is hopeless... :^)
