Externally, the C=64 Aldi had same case colour as a standard C=64 but the keyboard was light grey, like the future C=64G and C=64C.
Internally, the motherboard was redesigned to minimize production costs, most of the TTL chips were removed, replaced with a new MMU chipset. First releases of this board had some compatibility problems with C=64 peripherals - they lacked the 9V user port voltage, but this limitation was repaired in the next revisions.
Although made in USA, the Aldi was sold only in Germany as a game machine through only one distribution channel, a supermarket chain called... Aldi, hence his name, given by the German 64'er magazine.
In 1989, the C=64 Aldi would be replaced by the grey C=64G which would use the same motherboard.
