Changes
The only difference was the interface.
The interface for the CPC consisted (as well as newer RS232/USB versions) consists of:* 8 single bit inputs ports (eg. for sensing when a robot-arm reached its end-position)* 4 "bidirectional" ports (for motor control) (here "bidirectional" rather means "three-state-output" aka "forward/stop/backward")* 2 analog inputs (eg. for temperature sensor)
== Technical == Fischertechnik has built several interfaces:* 8 single bit inputs ports.C64/VIC20 probably required a custom interface (?)* 4 bidirectional ports.Interface for one-directional printer port (used on PCs) (this might have been also used by CPC ?)* 2 analog Interface for RS232 port (used on PCs) (9600 baud, 8bit, no parity, 1 stopbit)* Interface for USB port (used on PCs) === Parallel Printer Port === This seems to be designed for one-directional printer ports.Data is read via BUSY line (which data is to be read is selected via DATA lines) (details on how the data is transferred exactly are unknown?). Printer Pin Interface Signal Pin2 (Data Bit0) Load-out Pin3 (Data Bit1) load-in Pin4 (Data Bit2) Data-out Pin5 (Data Bit3) Clock Pin6 (Data Bit4) Trigger-x Pin7 (Data Bit5) Trigger-y Pin11 (Busy) Data/caunt-in
