Just to let you all know, I found 4MB 9chip 60ns SIMMs at Fry's in Burbank. I didn't do any price shopping as I want to get it done. $18 for 1yr. warranty. So far they seem to work fine even though I had to change a memory caching setting to 32MB in the bios. Other than that, so far so good. I don't know if there is more to change in the AMI BIOS ver 2.3 1992. Thanks to all.

I've seen them advertised, but never actually heard of anyone using them. I often wondered if the ads were a mistake or if they really did exist and if they existed what kind of chips they used. Anyone know anything about them ... just for the sake of trivial knowledge?
