1)A one meg. cache module will be really tough to find, as most users went with the less expensive 256k cache and few of the one meg. caches were made and sold. The Cache Doubler is an accelerator of sorts. I've seen it advertised somewhere on the WWW. Even just adding the 256k cache will cause a noticeable increase in speed on your machine. I replaced the 180 megahertz CPU on mine with a 240Mhz. CPU from a C600, and it ran at that speed, according to Apple System Profiler. Maybe that, along with a 256k cache is all you might need? 2)I have a great softwares CD that won't mount to the desktop in some Macs. It's extensively, finely scratched, and I'm sure if I clean it it would mount to the desktop of more of my Macs. I would also clean the CD ROM with a cleaning disk, check the tightness of my cabling and rebuild the desktop in case of extension corruption or other hooey. If it does not mount and appear on the desktop, I'd try a mounting segment of a hard disk formatter, or Mt. Everything the control panel that does what it says. If you don't get any, "can't read this disk, want to format?" dialog boxes, then it's probably just the damage on the surface of the CD or maybe a problem with the burner that created it.
