The SuperCPU by Creative Micro Devices is an accelerator cartridge for the Commodore 64. It contains an W65C816S processor running at 20 MHz, providing 20 times the performance of the stock 6510 processor! CMD later added a SuperRAM Card option that could include up to 16 MB of additional memory. There is also a v2 version that offers native 128 mode support (also called SuperCPU/128). It is one of the most sought-after Commodore peripherals.

This RAM expansion unit by Creative Micro Devices was intended to be used as a RAM drive to accelerate disk access. It is externally powered, and thus will preserve the data even when the computer is turned off.

**Cheaper and faster than diskettes.**
|
|
|
|
This Quick Data Drive from Dean Electronics is dedicated to Commodore 64 and <$252$>Vic 20 systems. It uses a special tape called 'Wafer', of 16, 64 or 128 Kb capacity. This wafer was also used by a product marketed for the <$223$>Sinclair Spectrum, called Wafadrive. Various tests proved that the Q.D.D. was approximately 20 times faster than a normal cassette recorder and 2 or 3 times faster than the Commodore 1541 disk drive. The reason : data transfer routines (called QOS) much more efficient than those of Commodore, and a file management operating system (FMU) much more modern and powerful.
|
|
|
|
The Q.D.D. is however not more than an advanced tape recorder using a magnetic tape, and the delay to access a specific file still remains higher than with a normal disk drive. Despite its qualities, the Q.D.D. did not meet success because most C64 software was sold on disks or tapes and users had to acquire both Commodore peripherals before investing in a third powerful storage system.

The last model of the C64 to be sold was the 64G. It had the original "breadbin" case, but the color was much lighter, pretty much the same as on the [64C](/museum/commodore-c64c/) model, to match the tastes of the moment.
|
|
|
|
The keyboard could either be the original black model with graphical symbols on the front side of the keys or the cream colored c-model type with the symbols on top of the keys. It seems that Commodore just tried to use up all the parts that they had in stock which resulted in all kinds of weird color combinations. The motherboard was a small and simplified one, very similar to the the one found in the [Aldi](/museum/commodore-c64-aldi/) version, though some C64G are reported with more older classic C64 motherboards in them...
|
|
|
|
The SID chip used here is a MOS 8580 version, resulting in sampled sound playing on very low volume. The reason comes from a bug in the older 6581 SID that was removed in the 8580. Eventually a solution was found by grounding one leg of the 8580 through a resistor.
|
|
|
|
Some of these machines were made from [C=64GS](/museum/commodore-c64-gs-games-system/) game console parts when the console bombed. Most were sold with a game pack (some magazine adds show the same game module as with the GS) and was marketed almost as a pure game console which just happened to have a computer in the same package. The G-model kind of replaced the horrible GS.
|
|
|
|
Build quality is not very good, especially the case feels quite brittle. The model sticker says "Made in W. Germany", but the motherboards were probably made in Hong Kong in the same factory as the C-model machines and only final assembly was made in Germany. The machine was probably only aimed at the European market.
|
|
|
|
The G-model was clearly a final cheap gaming computer that Commodore made to get rid of the huge stocks of C=64 spares and GS-parts. It was sometimes also named **c64-III** or **C64 BN/E**.
