    Quadra 950 -- system quirks & bus errors

    Yes, plausible. @cheesestraws, what’s your configuration?

    Quadra 950 -- system quirks & bus errors

    I finally got around to do some more testing, and it seems as if my SCSI2SD 6 2020c has some issues regarding the stock SCSI-bus in the Quadra 950? It worked without a hitch together with a Jackhammer, but since I wanted to Install A/UX, I had to choose between the Jackhammer and Apple CD 300...

    Another Quadra 900/950 CD-Bezel (Caddy Style!)

    Thanks, and yes, that is correct, just open the caddy and put the CD inside. It is not the most convenient way, but it feels more professional. Recap is almost always a good idea, but floppy drive failure is usually due to other factors; broken eject gears and headers.

    Quadra 950 -- system quirks & bus errors

    No PDS card, but a WGS card would be fun to have. I’m running tests in HDT 2.0 right at this moment and ID 0 just failed! So, there is definitely something going on with SD or SCSI2SD card. I’ll have to dig deeper.

    Quadra 950 -- system quirks & bus errors

    Good input! I have tried a couple of drivers, but no difference in behaviour. I’m gonna try a new SD-Card. Next, I’ll remove the A/UX partitions just to see what happens.

    Quadra 950 -- system quirks & bus errors

    Hello, I have a Quadra 950, with a SCSI2SD version 6, set up for four SCSI HD devices at 2 GB each (ID 0, 1, 2 and 3). After installing A/UX on SCSI ID 1 using the partition map and the guidance from the A/UX Server Penelope, I have some trouble installing and using System 7.5.3 (only with Open...

    Another Quadra 900/950 CD-Bezel (Caddy Style!)

    Thank you. The bezel is printed in high-temperature PLA. I’ll check out the near matching paint! :)

    Another Quadra 900/950 CD-Bezel (Caddy Style!)

    I’ve been spending more time with my Quadra 950 recently. After successfully recapping and restoring an internal caddy-loaded 300 drive, I decided it was time to have a CD-equipped tower. But just as for many before me, the bezel-less front became an eyesore. So I decided to design my own. You...

    Flyback opinions wanted

    Well, the flyback I ordered had the correct specification, and making the switch went without a hitch. It came as part of an old Mac Plus upgrade kit that besides the flyback, contained some capacitors and diodes (nothing spells old computer parts like an OCR and Optima typed box). However, the...

    Interesting! I have asked them about it.

    Flyback opinions wanted

    I bought a pricy new old stock 157-0042C (I hope!?) flyback yesterday; since I’m in Sweden, everything becomes twice as expensive (shows how desperate I am @maceffects ;)). Anyway, I was poking around the old Artmix site to find more information about the Hyper Power Supply Rev. 4.1 to see if it...

    Flyback opinions wanted

    Thank you all for your prime conclusions. I’m not going to take the easy way out. Instead, I’ll keep my eyes peeled for a replacement analogue board or a new old stock flyback transformer. I’ll start by posting my needs in the trading section, and then I’ll jump on the eBay train. Eventually, we...

    Flyback opinions wanted

    When I was trying to figure out a video problem in one of my SE/30, I noticed some cracks in the flyback (perhaps common failure these days?). As a result, the flyback gives a buzzing sound, and the glow coming from cracks pulsate synchronized to the screen distortion. The PSU is a new Stratos...

    Radius PrecisionColor Pivot 0356 take apart guide?

    Hello, Yesterday I got hold of a Radius PrecisionColor Pivot 0356. The monitor seems to be in working condition; however, the physical pivoting function is very stale. I thought I peek inside to see if I can clean and lubricate all the moving parts, but the problem is that I can’t find a...

    New 3D-printed parts (ktkm)

    While I’m trying to find a decent 3D printer, that is not too expensive for the Q950 Nubus Slot; I thought I share my Macintosh Portable SCSI2SD Mount. Since I find myself taking the MP apart, a lot, I wanted something that could be self mounting without the use of too many screws, just like...

    New 3D-printed parts (ktkm)

    A couple of weeks ago, I posted in the Trading Post, about wanting to buy new Nubus slot covers (and CD-Bezel kit), and @elbaroni gave me a clever suggestion to look for 3D-printable parts (https://hackaday.com/2019/01/19/unobtanium-bezels-finally-modeled-for-3d-printing/). But then one of my...

    Quadra 950 squeaking noise and distorted video

    I’m testing a Quadra 950 in the hope of adding it to my collection. But it makes a subtle squeaking noise (not from the speaker), and the internal video becomes distorted when it reads from the hard drive. If I push down the mouse button, for instance, to make a selection in the main menu in...
