Woohoo! Finally I received a nice little package with two G3 upgrade cards (and one IMSTT card). This is great news for me to upgrade the PowerMac 9500/180MP that I have here.
Curiously, only one of its memory sticks (it has 2 32MB sticks) was being recognized by the system. I had to open it and it took me quite some time to figure out why (after some tweaking) the system wouldn't boot anymore. I have no idea why, but just zapping the NVRAM worked (i.e., Cmd+Option+P+R).
