"Thanks to this mutant computer terminal cleverly disguised as an industrial-grade, rack-mounted video game, you could create new waveshapes by specifying points on a graph or by sampling acoustic sounds. You could display the resulting waveform on the Waveterm's CRT screen in order to perform a Fourier analysis. Still, the Waveterm was limited. 'It was only 8-bit and had quite limited memory,' Palm [Wolfgang, the man behind PPG] offers. The microprocessor chip used in the original waveterm (which later became known as the 'Waveterm A') was a 6809."

The Waveterm A model also included 8-inch floppy disk drives. Later, the floppy drives were replaced with a smaller 5-inch type. The Waveterm was built around a German computer system made by Eltec Elektronik Mainz. This system was known as the
"Eurocom II", and used the Motorola 6809 microprocessor. The
Waveterm software was written in a computer language known as Flex. An Eltec PAT-09 ASCII keyboard can be attached to the Waveterm's ASCII port. It is not known what other keyboards, if any, can be used with this port. The PAT-09 allows the Waveterm to function as a non-proprietary Eurocom II provided the proper software is used. Below is a list of such software known to exist for the Waveterm A with 8" drives:
Waveterm/Eurocom II Software:
- Flex 8--- Operating System
- Flex 9.1--- Operating System
- Super Sleuth--- Program Analysis & Debugging Tool
- ASM Lloyd I-O--- Flex Assembler
- ScreenEditor--- Text Editor
- Sargon II--- Chess game
