  1. The SE/30 was the only one to get 040 upgrades. With time and effort, it may even be possible to make the Turbo601 work with it. The Classic "I" had some 030 upgrades: https://www.micromac.com/products/compact_macs.html (BTW, they have NO stock left.) It may be possible to add a ROM card to a Classic II motherboard to be able to boot from ROM: http://www.synack.net/~bbraun/classic2.html
  2. Everything Bomarc had is already online. And there doesn't seem to be any other sources unfortunately...
  3. Sorry guys for the lack of content on the site recently (BTW thank you @ArmorAlley and @ktkm for pinging me). My PSU had a similar issue before it eventually blew up (powering a defective power supply can only damage it further): The 5V rail was completely dead (mine didn't hiss though, are you sure it's not the camera??). When connected to the Quadra, it kept power-cycling every second or so. Powering it outside the Quadra (by shorting the blue and the white cables together) kept it "stable" but the rail was still dead. I suspect some regulator on the primary "input" board is caus
  4. Wow this thread blew up all of a sudden, thanks for your interest! I have ZERO parts right now, no 9150, no Crescendo, no adapter, no HPV card. I was just wondering if this kind of setup was even possible. I have a big gap in my collection at the moment between the 950 and my G4 Quicksilver. The 9150+G3/HPV would be the ideal machine but I'm afraid it'll take years or even decades before I can piece it all together. That said, we can certainly start making some mock ups and it's only a matter of time before those flex cables crumble away.
  5. I didn't touch the connector, I don't know those CRTs well enough to play around with the pinout. I simply removed the yoke altogether on both CRTs, taking note which way the connector was pointing (roughly), and reinstalled the one that goes with the analog board on the good CRT. Some info on how to take it out (there's only one screw to loosen, try with the dead CRT first) https://oldcrap.org/2019/05/03/inside-macintosh-crt/ The part relevant for you: Then there's the adjustment. You shouldn't have to twist any of the magnets (only if the display
  6. The types @Scott Baret mentions only apply to the yoke. I've once swapped a "type B" CRT from a Classic II in a "type A" Classic. Just replace the yoke and re-do the adjustments. The neck arrangement is also pretty much standard, given that you can also use green/amber phosphor 9" from other manufacturers.
  7. Hi there, I'm just wondering if this is possible at all. I know there's an adapter for the 7100/8100 but there's no mention whether it works or not in the 9150. There seems to be some logic on the ribbon cable, so making a replica would be damn near impossible. Any ideas?
  8. You know you can swap out the yokes right? The tube itself is identical.
  9. The original housing now has four extra holes and the ATX PSU was successfully installed last Sunday. I ended up using the largest standoffs (I still need to make sure they’re not shorting against anything) and some nuts on the logicboard side. Tapping the holes won’t work here as the metal sheet is too thin (plus standoffs always have a collar). So the holes have to be 3mm wide (i.e. M3 not M2.5) to install the Bicker BEA-630. If you’re using a different PSU, YMMV. Rough measurements for the space constraints: NB: The original standoffs
  10. The drill bits arrived today and the standoffs are still in the post. I'll do the drilling and the installation this week-end. I will only be shipping boards with a few hard to find (or specific) components (live wire connector, µ-controller...). The rest will have to be bought separately (e.g. on Arrow) using the BOM I'm still concocting. It will be mounted vertically, on the wall closest to the logicboard.
  11. I DIDN'T KNOW THOSE EXISTED. It will make refilling/bleeding MUCH easier! I wasn't able to repair mine (I think there's too much air in the system), plus the radiator appears to be leaking. Any idea how/where to find a suitable replacement?
  12. Great to hear and what a setup! I've had to modify the AC board and I'm letting it dry at the moment. I forgot to remove the middle plated hole for the monitor plug and this voids my clearance goal (a short could have happened with board degradation/age). So I removed it the hard way (ie with my iron set way too high and by poking around the pad). Once the header is installed, you can't see anything so another run isn't really needed. I did update the files and I'm confident enough to put them "out there". -> https://github.com/L-Delorme/QuadrATX
  13. @Toni_ It took me a while to test it (my Quadra being dead and all) but I can report that it works 100% correctly on my Q950 running 8.1. Vette! is my favorite game. Thanks for fixing this bug! Now if only it would run at double the resolution... Also do you think there'd be a way to fix the bisected singer in the intro? https://youtu.be/NtDgTz2peXw?t=74 Kuranov probably used an emulator but this bug also occurs on real hardware.
  14. @Byrd It triggers the round robin algorithm on Supermac video cards. Without one it won't do anything of course... Some context (from the QuadrATX thread where OVa first posted about his issue): @OVa That Supermac monitor should work with the 900's built in video... Clear the PRAM first and connect it to the Quadra. First generation (1998-2004) 4:3 LCD monitors that only have a VGA input (no DVI) usually work better with older hardware. Here's a picture of mine. Edit: Apparently resizing existing attachment does not work...
