First I will say that I am not MAC literate. My background is HP and SUN Unix and DOS/Windows. However every once in a while I get a stretch task at work.
So I am in the process of rebuilding a CNC machine controller, which is a PowerMAC 8500/132. The computer includes an Apple card: 820-0930-A, which from the web is a: "Apple PC/DOS compatible PCI card". I have looked on the Apple website at: http://www.info.apple.com/support/oldersoftwarelist.html
and nothing looked obvious. I was able to find the upgrade from 7.5.3 to 7.5.5 and understand that the SCSI controller driver is built into the O/S from that page. I looked around the rest of the web. Found lots of folks selling it (no driver or documentation) and a few with dead links to where the driver was supposed to be.
Can anyone point me in the right direction? Points to the first answer that connects me to a driver that works. If I'm dense and it is already included in the O/S, points to the first answer that allows me to verify its operation.
Take care and have a good day.
