Mention external version, add section about software
The AMSSIO interface is a [[RS232]] interface by the dane, [[Martin Zacho]].
As opposed to other serial interfaces the AMSSIO has is meant to by be installed on top of the [[Z80]] CPU in the CPC!. However the circuit can easily be built on a Lochrasterplatine (what's the english word? experimental board?) and connected to the expansion port as well.
AMSSIO exists in 3 different versions.
A new and improved version is the AMSSIO II.
== Software ==
The software for AMSSIO can simulate a disk drive and a printer on a PC connected via RS-232. The software comes in two parts. The first part is for the CPC. It replaces relevant parts of the jump block, redirecting disc and printer access via RS-232. The second part is called CPCSHELL and runs on a PC under DOS or Linux. Part of the PC harddisk can be used as a giant CPC disk via this mechanism.
A spare PC can therefore be used as a method to add a cheap harddisk to the CPC. Although the software required on the CPC reduces compatibility somewhat it works for most well behaved applications and games that consist of a single binary (no special loader).
