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!
