+1 on the SE as the best first compact Mac. They're cheap, durable, compatible, and expansion cards are fun.

Yep, I'm a fan. I was lucky enough to snag one back when they were dirt cheap. Unfortunately I did the internal display mod to use a PCI video card and I really hacked it up in the process, because I was a teenager. I tore it down a few months ago and found some replacement cables for it, just...

Wow, nice score! Congrats.

Yeah, I don't think there's any overlap between OS 9 acceleration and dual-link DVI. I have a flashed Quadro4 900 XGL; it's basically a Geforce4 Ti 4600 with two single-link DVI ports instead of DVI and ADC. So it will do 1920x1200 but not 2560x1440.

Very cool! Looking forward to seeing if (and how) you choose to upgrade it :)

Thank you. These Projovian things are a pain. Luckily all the generic 3512 boards seem to have the SOIC footprint, so it's a better situation than the VIA 6421 cards. Soldering still required, though.

Nice work @dosdude1! Is the serial EEPROM still required? That's a big hurdle to these being widely accessible. @NJRoadfan I have not done an exhaustive amount of testing, but the handful of SATA HDDs and SSDs I have tested with, which are mostly SATA II and III devices, have not had any issues...

@adespoton No matter how much AI you throw at it, mining bitcoin on anything but the most efficient modern hardware costs more to run than the bitcoin value it generates.

Nice find, @finkmac! Thank you for posting it. I will not try flashing another card, though, until you also dump the contents of this EEPROM, which I think is a AT24C02B: Sorry, I have been burned before :)

Thanks guys! Yes, I was measuring with the CPU board unplugged. The clock goes out to the rest of the computer, but only via a buffer, MPC904 on the Apple card and ICS9112-17 on the Sonnet card, so it should be terminated on the card. Weirdly, the MPC904 appears to be designed to work with a...

With the help of Tiny Turbo, I was able to push my 7600 to the promised land of 60MHz bus speed. I took a 180MHz 604e card (the 630-2490-A in the table above), set its multiplier to 3x, and removed R49 to set its CLKID pins to match a 60MHz Power Computing card (I meant to tag @Fizzbinn above...

I had an idea about two weeks ago: I have a lot of ideas; not all of them are good, and not all of them get seen through, but this one seemed good enough, and was pretty simple to implement, so here we go: It's a potentiometer-adjustable silicon oscillator that fits in the common half-size...

Man, that's brilliant. I gotta start using that one at work. I agree the concept is fun, and I'm glad you're having fun with it. Just needed a bit of polish before releasing to the world. I expect we'll be seeing it on Hackaday soon regardless.

Just be sure not to use white solder mask--Ariston Technologies has it trademarked! :LOL:

Depends on the OS version. By 10.4.11, most brands of CD/DVD-RW drives were supported well by the OS and/or Toast.

That's a fantastic idea, and well executed!

I have tried the VT6421 cards in a 5400 and a 7600. I'm ready to declare that they just don't work well in Old World machines. They show up in System Profiler, and connected drives will appear and work to some extent, but file transfers will hang, OS installs will fail, and booting always fails...
