OK, another update, I have figured it out why it wasn't working in 8.5, maybe it helps you... In 8.5, in Monitors and Sound, there was no output device available and testing the alert sounds just flashed the menubar. In the Apple Extras folder there is the old Sound control panel. I opened it...

Ok, an update: I booted my SS into 8.5 with all other settings left alone, and I got the Sound Tool error.

I don't remember the specifics of the issues, but I gave up trying to use Sheepshaver on my MBP. It never worked as smoothly as the windows version for me. I remember playing one of the Escape Velocity games and being irritated by something that I couldn't get to work nicely, but it wasn't...

I have Sheepshaver installed on my windows pc so I gave it a try and it runs fine. Sheepshaver 25-3-2015 build and 5-6-2013 build, both work fine 9.0.4 Macintosh Garden download Windows 10 host

I have a 5300 with fragile but intact hinge plastics, and I have the necessary cad/cam/reverse engineering skills and equipment, and a cnc machine shop to effect any solution I come up with… Unfortunately I don’t have any real spare time and an already pretty big list of projects. This is...

I did the exact same thing to my Q700 floppy when I cleaned and rebuilt it - I had no choice but separate the heads a little as they had some hard build up on them that wouldn't clean off with normal methods, and in the process I bent the spring and broke one of the screws. Can confirm that it...

New RB methods are always interesting, if you don't mind sharing please do post your techniques!

I have a tibook with, I think, radeon mobility 9000

Ah ok, makes sense that I have rarely seen it as I tend to use 7.6 or 8.1 on my quadras

Which system version are you running? Does the Quadra 700 actually support 24bit addressing at all? I didn't think it did...

In the world of keeping old industrial electronics alive, Stabilant 22 is liquid gold. https://www.stabilant.com/sizes.html I dare say it would be equally great on simm socket contacts....

I have a SCSI2SD V6 and recently purchased a ZuluSCSI RP2040 and can happily recommend both. I haven't done extensive testing with the ZS yet, but I suspect that the SCSI2SD V6 is still the best raw performer. Not relevant unless it's connected to a fast bus like a Jackhammer or SEIV - both are...

Stop moralising. OP is an upstanding member of the forum and should be given the benefit of the doubt. You are jumping to conclusions unfairly.

Since I happen to have a wombat board right here next to me, I can confirm that C39 and C40 are identical. Looking closely at your photo, I can see that there is a lot of sludge remaining in the bottom of the scsi connector - if it's there it's likely elsewhere too... It may be that your board...

It would surely be possible, but there is no additional silicon on this card for any acceleration or dsp. It's still a very cool card, as there were apparently very few 040 pds graphics cards ever on the market (I can only think of one other - the Mira Rainbow GX), and this one seems to be...

An unrelated but interesting take away from this discussion is that sometime during the production lifespan of the first Quadras, Apple changed the numbering scheme of their custom ASICs to the "343S" system, and there are differently numbered but identical ASICs out there from this time period...

Lol, no I missed that!

Related: The DAFB (framebuffer controller) on my Quadra 700 has a different part number so I dismissed it, but I found this image which clearly has a 343S0128-01 populated in the DAFB, which lends credence to the notion that this is a duplication of the Q700 video subsystem... I can't identify...

No apologies required, I perfectly understood your concerns! As I hinted at previously ("borrowed" ASICs), I strongly suspect this board is simply a duplicate of, or based on, the video subsystem of some existing 040 mac, hence the use of Apple branded ASICs. From a brief glance U1...

Awesome! That is one very rare card you have there, I wonder how many were made?
