Before you tear your machine apart, read the manual about installing more RAM several times. It tells you exactly what you have to remove, how the chips fit in, etc... I read this 2-3 times until I could visualize every step. >Once you have the plate unscrewed, disconnect the power bus from the system >board and the SCSI and floppy cables from their drives.

You have to relocate the 1MB of fast RAM (if you have a 2MB system) unless you're installing 256x4 ZIPPs. >Be careful inserting the chips, first place them in the socket and press down from >both sides with equal pressure until it is firmly in place. MAKE SURE YOU DO IT >RIGHT THE FIRST TIME, FOR IT IS VERY HARD TO REMOVE THE CHIPS ONCE INSTALLED >WITHOUT BENDING THE LEADS. I placed the pins in the sockets, grasped them by their middle, and kinda wiggled them into place. I tried to just push them into place, but it took too much force to get anywhere that way. Just kind of exerting a steady pressure on the chip, and wiggleing it forewared and back seened to work well. I did the same only gently pulling, and they came right out (when I was checking for some problems with the chips). Sean -- From the desk of Sean Reifschneider. Isn't Amiga UUCP great?
