= History =
The SYMBiFACE line of expansion cards were developed and evolved as follows: [https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/symbiface-iii-in-development/msg249979/#msg249979 Source]
*The [[CPC-IDE]] ("SF1") was developed by Dr.Zed in 2004.
*The [[SYMBiFACE II]] was developed by Dr.Zed in 2005.
*The RSF3 was developed by TMTLogic around 2023.
[[Dr.Zed ]] and [[TMTLogic ]] are two different persons. We simply call them both cards SYMBiFACE, since the first one was a [[SymbiosiS]] production.
The SF3 was, in a way, the successor to the SF2, as it's again multifunctional hardware, offering many components that are also particularly useful under [[SymbOS]]. However, they're not compatible and were built by two different hardware developers ([[Prodatron]] simply supported both projects and helped with shipping).
The RSF3 reunites the lineage as it is compatible with both the SYMBiFACE 3 AND '''and''' the SYMBiFACE II (and also with the M4 Board and many other CPC hardware expansions).
