Notes
Supported by "Starwriter". A "Z80 STI" is a 40pin MK3801 chip from Mostek? Details on that chip are reportedly found in the "MOSTEK 1982/1983 Microelectronic Data Book" (but there are no data sheets in the internet yet). The MK68901 seems to be a newer/similar chip (but neither port addresses nor pinouts are backwards compatible). Schneider is the german distributor for Amstrad hardware (however, this interface seems to be Schneider's own invention, not an Amstrad product).
