    Color Classic Mystic Upgrade

    Having done a Takky mod about 20 years ago, IMHO it's not worth it these days. The Mystic mod is reversible (and can require no hardware mods if you're willing to forgo VGA and use the system enabler trick), whereas Takkys were finnicky at best and required serious permanent changes to the CC's...

    PowerBook 2400c Cardbus mod

    So I had both of my 2400s out this weekend and remembered to test them for CardBus compatibility. In short: On the 180MHz model, nope. I tried hot-plugging a card in, and as soon as I did, the Finder crashed and reloaded. The machine kept running, but when I went to shut it down, it froze. I...

    Macintosh LC 575 “Mystic” logic board recap, install into Color Classic II chassis

    Does that modification to the board affect its ability to work in a 575 chassis? (A CC II is on my list of machines to get. Someday!)

    Restoration: Macintosh SE with Water Damage

    Wow, nicely done! I'm curious about the screen burn-in, any idea what application it's from?

    Period-accurate benchmarking tools?

    So I tried Speedometer 4.02 on both machines and it works great -- the results it generates feel accurate to me, considering the systems. MacBench, however, was a no-go on one of them. I tried versions 3 and 4, and for both, they just hung at the splash screen. I even wiped the machine and...

    Period-accurate benchmarking tools?

    I'm working on a project where I need to benchmark a couple of Macs from the 1993-1995 era to see how they compare, at least in terms of computational performance. I never really got too much into this during that time period, so I can't remember many benchmarking utilities. Can anyone recommend...

    PowerBook 2400c Cardbus mod

    From what I recall, the 2400/240 model officially supported CardBus, and considering that the machine has its CPU on a daughtercard, I'd be *really* surprised if Apple bothered to redesign the motherboard just for that feature. Architecturally, the 2400 and 3400 are similar, and the 3400 also...

    2.5" -> 3.5" SCSI adapter

    The adapter provides power to the 2.5" drive, and does indeed "move" the SCSI ID jumpers to the adapter's PCB. Here's a shot of the adapter connected to a drive; the SCSI jumpers are on the right and the power input is on the left.

    Anyone want to pool some cash together for a Twiggy Mac?

    Interesting, that's a different Twiggy prototype than this one: https://www.applefritter.com/content/macintosh-128k-prototype-twiggy-drive So I'm wondering if it's the second machine from this story: https://www.cultofmac.com/239280/twiggy-mac-lives-quest-to-resurrect-worlds-oldest-macintosh/

    2.5" -> 3.5" SCSI adapter

    I'm a little late to the party, but I picked up one of these earlier in the year and it works as advertised. Not as much geek cred as building a PCB yourself, of course. http://www.cablesonline.com/25lapscsihar.html

    My SE/30 is SimaSima Macintosh.ozt~~

    I know that SE/30s can be *very* picky about RAM. I had a similar problem with mine, and was only able to resolve it through a lot of experimenting with different RAM combinations. The ideal scenario is to have all 8 slots populated with identical modules.
