The Super 1750 Clone was a 512 kB
RAM expansion unit designed as a tiny, but compatible, third-party replacement for
Commodore's then out-of-production
CBM 1750 REU. Manufactured by
Chip Level Designs, the Super 1750 Clone was sold by
Software Support International.

** Less power consumption, so did not require the C64 to be upgraded with a heavy-duty
power supply
A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a r ...
