    Performa/LC 580 Overclock

    Yes exactly. Need to move a couple resistors. There are two revisions of the board that place the resistors in a different place. As extracted from the source page: Note: there are two versions of this board. The Rev A board is marked 820-0624-A on the top of the board in the corner next to the...

    Ah yeah here we go: https://github.com/tghw/macproxy The link is originally from this page where Stefan Wolfrum hooks up to the net with a Macintosh Plus: How I introduced a 27-year-old computer to the web

    Someone made a proxy. Let me try to find the link.

    Power Macintosh 7200/7300/7500/7600 Power Button

    Ooops. I did attach the stl and step file but looks like the forum doesn't like those and just removes the. I zipped them instead now and attached it to the previous post.

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    Yeah from what I understand Emu68 is running in Supervisor mode based on the post of the developer Michal Schulz: https://www.patreon.com/posts/emu68-meets-54448728 User mode doesn't sound like it would make much sense. On the PiStorm -> Machintosh discord AlexCL has been testing the PiStorm...

    Recapping PowerBook 100 Series 7.5v 2A AC Adapter

    I agree with lausvi to use a vice to open the adapter. I was able to open my M5140 adapter using a vice without damaging the case. As you tighten the vice it makes the sides want to bulge out thus breaking the bond between the two halves of the adapter. Once one side is open, rotate and repeat...

    Performa/LC 580 Overclock

    If anyone was wondering why the hard drive benchmark is so much higher than the stock hard drive, it's because I'm using a 40GB Seagate Momentus 2.5" drive.

    There's actually a project in the hardware section of the forum for a variable clock speed mod: "Spicy O'clock" project has started

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    That's really cool. I've been long interested in PDS accelerators but have very limited knowledge in the implementation of accelerators and electronics in general. This is absolutely great info :) Any thoughts about using a PiStorm as 68000 accelerator in the Mac SE PDS slot (assuming the FC...

    Performa/LC 580 Overclock

    I bought from this seller and the chips sent were legit XC68040RC40M cpus: https://www.ebay.ca/itm/383675636030 The fact that they aren't perfectly clean is a good sign to me since they are likely pulls. I'd be wary of chips that look supper clean with bright print on them. Chances are they...

    Performa/LC 580 Overclock

    Yeah the are incompatibilities though. I like playing The Dark Queen of Krynn and sound doesn't work on PPC.

    Performa/LC 580 Overclock

    Yeah I tend to gravitate more toward the 68k Macs as well. Full 68040@40Mhz is pretty nice :)

    Power Macintosh 7200/7300/7500/7600 Power Button

    Here's the STEP and STL files to add the clips back to an original button. I'm tempted to make an extension of the original button to make it so it won't need to be pressed so much and get stuck sometimes like the original. License under CC BY-NC-SA 4.0

    Power Macintosh 7200/7300/7500/7600 Power Button

    I've had a snap on fix design on my todo list. To me using the original button that's broken and adding two new plastic springs would be ideal so it will loo orginal. I'd probably make it from PETG since that has a lot of flex but is very hard to snap. Spring going around the original part...

    Performa/LC 580 Overclock

    Yeah would be nice if there was a benchmark app that could use the internet to upload results. Any particular reason you prefer Norton Utilities over others like Speedometer, Mac Bench, Apple Personal Diagnostic, etc?

    Macintosh Portable 34 pin to 50 pin Hard Drive Adapter

    Here's a link to my Git repo for a Macintosh Portable 34 pin to 50 pin hard drive adapter. Tested it with a BlueSCSI and seems to work alright. https://github.com/alxlab-zone66x/macintosh_portable_50-pin_hard_drive_adapter I'll probably be selling some in the future to help fund my various...
