Another victim! No you cannot upgrade the Mac II to 1.5 Meg. The Mac II only allows memory sizes of 1,2,5,8 etc. I know this because some people here bought some upgrade kits to give themselves 3 meg. Now they are all upgrading to 5 meg. What you can do however is take _all_ of the 256K simms out of your Mac+ clip a resistor (maybe), add in another resistor (maybe), thus making your mac+ 2 Meg. The Mac II can now take all four of the 256K simms to give 2 meg. Hint for people upgrading Mac II's this is how to figure out what sizes are allowed. 4x256K simms = 1 meg 8x256K simms = 2 meg 4x1M simms = 4 meg but why would anyone bother since 4x1M + 4x256K simms = 5 meg one meg came with the machine 8x1M simms = 8 meg 8x2M simms = 16 meg when 2M simms are available 8x4M simms = 32 meg when 4M simms are available 32M + 6x16M per slot = 8x16M = 128 M but no video card Or maybe you would just like a HyperCube made of Macs over AppleTalk.
