I just happened to be in the right place at the right time today to grab this one(or I should say it was offered to me before it went to the garbage). I also picked up a whole bunch of cables and other odds and ends from the same source, including the keyboard and mouse pictured here. This one is running OS 7.5, and is loaded up with a bunch of really good software that I can actually still use...in particular it has a copy of Chemdraw, the current version of which is over $1000. The original 2gb drive is close to full. I attempted to install a second 2gb drive I had on hand, but haven't yet been able to get the computer to recognize it. The main drive is set to ID 0 and the second drive is set to ID 1(and termination off), so I'm not really sure what's going on unless the drive is just dead(the CD drive works, so I don't think it's an ID conflict with this). My SCSI knowledge is close to zero, so it's also entirely possible that I'm doing something wrong. Unfortunately also, my nice 15" Apple CRT decided to go kaput this afternoon and I'm stuck with the 12" for the time being. I need to order some DB-15 to VGA adapters so I don't have to keep tracking down Apple displays for older computers(I can get pretty much all the 15" LCDs I want for free). Until they arrive, I may use the S-Video or Composite ports to connect it to a TV. Also, most of the references I see to upgrading the ram refer to using "60ns" or "70ns" 168pin DIMMS. I have tons of 168pin PC66 ram(which I think translates to being a fair bit faster than 60ns). What are the chances of this working correctly in this computer? From what I've read in the service manual and looking at the computer, installing ram looks to be fairly involved. So, with that in mind, I'd prefer to not "try it and see" as I usually would. Does anyone have any experience with this?
