Wow! Good info..
1.) The unit is a dual 450 MHz processor version with four RAM slots for 2 GB of RAM. On checking, I find 1.5 GB present.
It came equipped with an ATI Radeon 9000 Pro 64 MB video card. Interestingly, when I ran the OSX 10.4 CD to get the
system inventory, it stated that no display was connected, although I was obviously reading that bit of information from one.
I also found on the MacIntosh Garden web site a driver for that video card. One comment above was that I needed the stock
ATI 128 Rage. I do have one of those left over from my Digital Audio machine, so I can try that to get the firmware updated.
2.) On further inspection, I found an Adaptec SCSI card mounted in one of the PCI slots..
..so I removed it and rebooted.
Since I'd forced the unit off with the power switch, Disk First Aid popped up, checked the disk, and found nothing wrong.
I clicked on the provided button (yes, the mouse click worked here) and the boot finished. I got what looks to me
like a normal OS9 desktop. And I get a dialog box that says that the OS is checking the system. That process ran all night without
resolution, and the mouse worked as before, moving the cursor but not clicking.
3.) I replaced the newer MacAlly keyboard with an older version that had worked flawlessly on an old iMac DV G3 with OS9.
Here, it would not work; typing up or down arrow did not move the selection away from the system HD (folder?), nor could I
open that folder with command-down arrow.
4.) So, to summarize:
a.) Are the device drivers or extensions for OS9 included in the OS install like Linux, or do they have to be added afterward,
like Windows?
b.) If I wanted to add the ATI 9000 video card driver noted above or some other USB driver, how would I do that?
c.) If I change the configuration with the older video card or another keyboard, do I need to reinstall OS9 to take advantage of that?
d.) Why on earth does the mouse work with the install CD and with Disk First Aid, and with OS10, but not with the desktop?
And why doesn't the keyboard work when the mouse moves the cursor?...
Thankyouthankyou for responding. You folks are a wealth of knowledge!
