Здраствуйте ребята,

Hello, I have a broken Poisk-1, and I`m plannig to repair it. Probably I have to change some or more of ICs on motherboard, so I can do some upgrades.
I`m interesting is it posible to do convertion Poisk-1 ver 1.03 with 128kb to 512kb onboard?
Is there someone has do this conversion already?
I`m writing in English becasue my Russian is not good, hope is not problem.
