CBM 8032 AV - Telex - Budapest 26.2.2022

CBM 8032 AV - Telex - Budapest 26.2.2022 from Robert Henke on Vimeo.

"The CBM 8032 AV performance is running on five iconic Commodore CBM 8032 computers from 1980, connected together to form an audiovisual instrument, played by the artist on stage.

These computers from the beginning of the personal computer age can only produce simple green low resolution graphics and they need custom hardware to create sound. Low level programming in assembler is necessary to achieve the real time audio and video signals, but these limitations also inspire a very specific and unique aesthetic, which defines the identity of this project.

Three computers create sound, the signals are calculated directly by the CPU (6502, 8bit, 1Mhz) and sent to a 8bit DA converter. Sound is further processed using a Publison DHM 89 pitch shifter from 1978 and a AMS RMX 16 reverb unit. Video is created by a forth computer, also calculated directly by the CPU, written to 2kByte screen memory. A fifth computer controls the other machines via a custom sequencer. The entire project runs on our own software.

This recording is an excerpt from a concert in Budapest, February 26th 2022.
