/* Technical */
Fischertechnik has built several interfaces:
* Interface for Commodore 24pin User Port (used on C64/VIC20 probably required a custom interface (?)* Interface for one-directional 25pin printer port (used on PCs) (this might have been also used by CPC ...?if so, with 34pin/36pin connector, of course)
* Interface for RS232 port (used on PCs) (9600 baud, 8bit, no parity, 1 stopbit)
* Interface for USB port (used on PCs)
