/* Amdrum */
[[Image:cheetah logo.jpg|right|thumb|250px|Company logo]]
A drumkit by the British company [[Cheetah]].
The drumkit was able to play 8bit sound samples.
Quality of the playback was nice, considering the time and price.
The samples was read from the suplied tapes.
There was serveral tapes with different themes!
Along with the Amdrum came a sequencing program.
It was possible to copy the samples to disc, but the sequencing program had to be patched!
Amdrum was probably Cheetahs version of the SpecDrum (As revealed on the PCB "AMSTRAD SPECDRUM")
No CPC emulator supports the Amdrum. To hear 'Amdrum' in action the Spectrum emulator Spectaculator emulates the SpecDrum.
No other software than Cheetahs own sequencer is know to use the Amdrum.
== Technical Specifications ==
The PCB(oneside) contains five chips:
