Would someone with a Quadra 700/900/950 be willing to test a program for me?

I've been working on an Apple Sound Chip tester app that gathers a bunch of info about how the different ASC variants in 68k Macs work, mainly in order to help improve the accuracy of emulation. I've tested my program on a bunch of different Macs, but I don't have access to anything equipped with the discrete EASC chip before it got shrunk down and combined into bigger ASICs.

The app simply runs some tests with the registers, FIFOs, and interrupts. It makes a few blip sounds out of the speaker, takes a few seconds, and then displays a window with info about the ASC. Is there anyone here who has a 700/900/950 and would be willing to run the program and tell me exactly what it prints out? A screenshot or a picture with your camera of the window contents would be great.

It would also be interesting to see what it displays if you run it on a PowerBook 140 or 170.

The app (and source code) is here: https://github.com/dougg3/ASCTester

The easiest thing to do is just download the ASCTester.bin file, which is encoded in MacBinary.

Thanks!

To expand what Doug said, a PowerBook 140, 145, 145b, 160, 165, 165c, 170, 180, or 180c would all fit the bill here.

We'd also be interested in results on a PowerBook 5xx (without the PPC upgrade) and a Quadra/LC 630.

I'll have to dig out the Powerbook 180c and run this.... when I have time.

and a Quadra/LC 630.

Thanks! I added these expected results to the README.

Edit: Another useful one to check would be a PowerBook Duo, if someone gets to it before me.

 

[Arbee]

Awesome, thank you! That verifies that PrimeTime II behaves the same as PrimeTime and IOSB.

A few more machines that I don't expect to show anything unexpected but I'm going to ask anyway: a IIvx / IIvi, and a Mac TV.

I don’t have time until this weekend. But if no one else gets it done before me, I can do it for a PowerBook 500, PowerBook Duo, Q700, and Q950.

Quadra 950 and a powerbook 520c.

I have Quadra 700 have one too, but unsure if the quad doubler will affect you test. If it does I can remove it.

 

[Arbee]

Thanks Callan! Interesting that the 950 and the 700 are slightly different, but that may well be the quad doubler. If it's not a big hassle to try without it I'd love to see that, but if not that's OK too.

Will do
