I had an old mod article that basically said you just had to add 4 more 256 dram chips to the board but I'm not sure if I have to modify any jumpers/ cut traces etc? also I understand that this onboard ram will interfere with the additional 512K on the trapdoor A501 and possible the clock??

anyone done this mod or knows where I can find some info on it?? I found the dram chips and hope to get the ol soldering iron going again soon

I´ve did this to a friend´s A500 a long time ago. As far as I remember, there is a jumper to set, and nothing more than this. I´ll try to find the magazine that had this article.
