There was more than one revision of the Multiface 2 for the Amstrad:
* Original version which was always visible to software (- first appeared in Amstrad action in 16 (January 1987)
* 2nd version which has a manual switch to control visibility to software. (before September 1988)
* 3rd version which has an automatic switch controlled by PAL ICs to control visibility to software. This is called "2+" by Romantic Robot and was first advertised in Amstrad Action issue 36 (September 1988).
