KC Compact Expansion Port
The KC Compact has 58pin, special-type connector

Expansion Port on Aleste 520EX Expansion Port
The Aleste 520EX has a 62pin, male edge connector.
A1..A25 Same as <odd> CPC Pins 1..49 (ie. SOUND, A15, A14, etc.) B1..B25 Same as <even> CPC Pins 2..50 (except B20=NC, instead /BUSRESET) A26 MAP14 B26 MAP15 A27 MAP16 B27 MAP17 A31___________________A1 A28 MAP18 B28 MAPBLK |___________________| A29 /INTA B29 /DISP B31 B1 A30 Agnd B30 /CPU A31 Aucc B31 HIGH
Most of the extra pins are DMA related. The Aucc/Agnd pins are meant to be smoother voltages then VCC/GND (for use with Audio expansions).
Amstrad PCW
The Amstrad PCW has a 50-pin Expansion port, too. But it's pin-outs are entirely different as on CPC.
