Lines: 10 I would like to upgrade my 520ST (new model) to 1Mb RAM. My ST contains a bank of 4 256kx4bit RAM chips (NEC part number D424256C-10) with space for 4 more. It looks as if the decoupling capacitors are already there. Does anyone know how to do the upgrade? Is it just a case of putting in the new chips ? (In sockets of course). Please mail replies and I'll summarise. Thanks for your help. Regards, Warwick
