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.

- title: QUICK DATA DRIVE
subtitle: ''
text: |-
**Cheaper and faster than diskettes.**
This Quick Data Drive from Dean Electronics is dedicated to Commodore 64 and &lt;$252$>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 &lt;$223$>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.

text: My childhood machine. My mom bought it second-hand around 1996, long after the decline of the 8-Bit era. After we moved on to Windows PCs, the C64C and its peripherals sat boxed in in the basement. This year, I refurbished them, retrobrighted their cases, added heatsinks to the sensitive components. Everything works like a charm, and it''s still a great experience to tinker around with them.

I have got the mine on 1992/93 and that still works good now.\
I have wrote a lot of programs with it and after 20 years i am yet happy to make the same!

text: This one is my favorite C64. It has better picture quality compared to my older C64:s and the sound chip does actually sound better except for old-style digitized sound. But if you have a look on the Vicious Sid demo, you will see that the 8580 chip is doing much better when playing samples using their mechanism.

The C64 was my very first computer and it still runs today - perfectly. I have many old computers but the Commodore machines are very special to me. I just love the very simple an classic design and the hardware capabilities.\
But no C64 and 128 is complete without GEOS, the best OS of all times. It''s still mindblowing what Berkeley Softworks has done. They really managed to run a GUI on a computer with only 64kB of RAM. It''s really amazing.

text: I had one of these. The only drawback was the sound chip itself. You couldn''t hear digitized speech very well. In my experience with one of these, the digitized speech were very faint. The chip used was a MOS 8580, which could be replaced with a MOS 6581, which worked better. Other than that, I liked the styling of the case. The board was very small, and used fewer chips than the previous model it replaced.

http://www.scribd.com/doc/40437/Commodore-64-Users-Guide Although this is aimed at a C64 the C64C is a C64 re-packaged. So the principle should still apply.
I hope this helps, I just got mine powered up although there''s some repair work involved.

I am a guy who had a machine like this one!
I would want to think if the c64c form (with keyboard slope and other anti slope towards the grid) was based on the generic graph of the envelope generator: "attack" "decay" "sustain" "release" /$\_\

The Commodore 64C was simply the original [C-64](/museum/commodore-c64/) repackaged in in a beige [C-128](/museum/commodore-c128-c128d/) style case. Internally, Commodore integrated most of the hardware onto a single VLSI chip.
The new model did not differ much from its predecessor, the only innovation was the flatter case, which made the keyboard (which had off-white keys) more ergonomic (it looked like the C128 case), not as high as than the old one. But the new case did not only have advantages: due to its low profile and additional metal screening, some of the numerous hardware expansions did not fit anymore. This was changed with the [C64G](/museum/commodore-c64g/).
The official name for this model was "C=64 C", but nevertheless the German 64'er magazine decided to call it "C64-II" (because the first units didn't have the new name on the label at the bottom), the badges on most of the 64 C's just says "Commodore 64". They pointed out that this name was only valid for the 64'er magazine, but since the 64'er was the magazine for the C64 for a long time, the name was widely accepted and so this model is mostly known as "C64-II" in Germany.
Commodore took advantage of the launch of the 64C to improve its range of peripherals. The machine could be delivered with:\
• the **1541C** disk drive, internally the same as the previous 1541, but with a beige case,\
• the **1541-II** disk drive, a smaller 1541 with external power supply and a beige case\
• The **1351** two-button mouse which could operate in either proportional or joystick mode,\
• The **1802** color monitor which accepted both composite and RGB video signals,\
• The **1764** RAM expander which plugged into the expansion port and boosted the system RAM to 256 KB.
First 64C were bundled with **GEOS**, developed by Berkeley Software, a good window and icon opating system, considering that it ran on a 8-bit processors and 64 KB of RAM.
Sadly, the 64C was launched at the wrong time, at a wrong price (about $80 more than the C64). At that time the competition was hard with the new [Atari](/museum/atari-520-st-st-stm/) and [Amiga](/museum/commodore-amiga-1000/) 32-bit computers. The 64C thus didn't meet a large success, except in some European countries.
