In Modeum (*) Rudolf Hess (1986) (*) Modeum cf.: Modem from Modulator / Demodulator and Te Deum (Dead mass)
In those days (1986) we, at least I did, build our own electronic devices, in this case I made a modem with electronic parts from the Americain Tandy Corp. , which happens to have in that time quite a substantial amount of shops in our neighbourhood. They had shops in every part of town and even demonstrated the first PC to the locals, introducing them a complete new electronic world. The idea was to connect my German assembled and designed VIC20 (in Europe nicknamed VolksComputer due to their cheapness and simpleness) with my brothers US branded CP/M fueled SuperBrain. As both machines had a quite open structure it was rather easy to use their peripherals (printerports, memory-expansion slots) to implement our own add-ons . There was no internet, the only way to communicate over a longer distance, interlocally that is, was by using the network that was already there i.e. the telco's. To be able to send a signal through this network the data transmitted had to suitable for their network constraints. for teleco's this was the narrow frequency band used for wired voice transmissions. So we had to modulate our outgoing digital signal using frequency shift keying (FSK) techniques to conform to the standards the telco's imposed. The receiving side has to demodulate this FSK signal back to its digital origin. So I did, it turned out to work fine, using our own written assembly code to program the where abouts of the electronics. When we were not soldering or writing specific driver software we used to walk around the streets, in Amsterdam NL that is, and did live interviews, the following is an example of such an interview. http://burgerwaanzin.nl/inmodeumrudolfhess.html (in Dutch!)
