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.
