The memory should work, just try it and if it doesn't, the memory could be bad, wont hurt anything to try it.
If it booted before but wont boot now hard drive may have died or battery onboard is dead and it "forgot" the boot drive. Start up from a system disk then see if it can still access the drive to find out. ________________________________ From: [email protected] <[email protected]> on behalf of V.

First the question: would 60ns FPM SIMM 72-pin memory work? Most 70ns RAM I found is really small capacity but I want to put 32MB in this baby. Also, somehow, despite booting into OS 8.1 the first time I started it, the Performa no longer has an OS now. I get the ? floppy icon. How did that happen?

I've done a fair bit of research into vintage Macs before I bought one but there's still some questions I haven't found answers to. 1. I haven't opened my Performa up yet, but chances are it still has the original 68LC040 and I didn't get lucky by buying one with a proper 040 upgrade. I've found decently priced 040 chips on eBay but they're all 25MHz chips, which would be slower than the 33MHz LC that's (probably) already in there. Would a 25MHz 040 installed in a motherboard with a 33MHz clock crystal run at 33MHz or is 25MHz the maximum speed it's capable of? 2. I've heard the SCSI controller in the 630 is absolutely abominable due to being slow and outdated. Can it be replaced with a more modern controller from another Macintosh? I appreciate hearing from some people with more Mac experience than I have. -- -- ----- You received this message because you are a member of the Vintage Macs group.
