When I was refurbishing my used dual 1.25 MMD last year, I pulled the 1 gig of RAM that came with the machine and purchased all new, same lot & and capacity to upgrade & max out at 2 gig of RAM. I'm glad I did this because it ruled out any problems that might be caused by a RAM glitch (hard to track down). The machine has worked very well in both OSX & OS9. If you can afford new RAM, I can recommend this option. -jonny /// >This is an old problem with people upgrading their RAM one stick at >a time.
