Stack Memory
This is more like it - massive memory boards, cheap injection moulded covers and hand-typed user guides! This is a user-configurable RAM pack made by Stack Electronics, who made a few CBM peripherals such as the 4-way C64 expansion board. It had to be user-configurable because some games wouldn't run with more than a certain amount of memory present. The 2 switches visible in the 2nd picture selected the amount of memory available.
