- Note: Despite of using a 34pin edge connector, Amstrad used a 36pin Centronics-style pin numbering. Pin 18 and Pin 36 do not exist on the 34pin edge connector.
- As shown above Pin9 is wired to GND (instead of Data 7), for upgrading, see 8bit Printer Ports.

CPC+ and KC Compact printer ports differ on Pin 16,17. Also, Pin 9 is controlled differently on software side (see 8bit Printer Ports). And, Pin 1-8 are bi-directional on the KC Compact.
Aleste Printer Port
The Aleste 520EX uses two 7pin DIN female connectors:
Pin X5.B X5.A X5.B X5.A 1 D4 D0 __ __ __ __ 2 COMMON GND / - \ / - \ 3 D7 D3 |(7) (6)| |7 6| 4 D5 D1 |3 1| |3 1| 5 D6 D2 \5_2_4/ \5_2_4/ 6 ? STROBE 7 ? BUSY Shield GND GND
According to the schematics, X5.B is only 5pin. But according to component map and all existing photos, both connectors are 7pin. The two extra pins are possibly unused. COMMON is /Joystick1 select, there is no purpose specified for it being on the printer port.
