This expansion card , created in 2023, is an evolution of the [[Symbiface 3]].
[[File:Poulette73-rsf3.jpg]] [[File:RSF3side1.jpg]] [[File:RSF3 side2.jpg]] <br> = History = The SYMBiFACE 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 [[Symbiface 3|600pxSYMBiFACE III]]was developed by TMTLogic in 2018.*The RSF3 was developed by TMTLogic around 2023. [[Dr.Zed]] and [[TMTLogic]] are two different persons. We simply call 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''' the SYMBiFACE II (and also with the M4 Board and many other CPC hardware expansions).

*DAC analog audio output.
*Wifi with antenna (speed 2 MB/s).
*[[RTC ]] clock for real-time date and time.*Duke [[M4 Board ]] emulation (partially).
*Infra-red port.
*Reset button.
*Substitution of ROM 7: ON/OFF Allows you to replace the original Amsdos ROM 7 with another stored on the RSF3. Warning: not compatible with all CPCs. May cause hardware conflict with Z80 data bus.
*SE-One: ON/OFF. Allows you to activate the emulation of the MSX SE-One card, which offers an MP3 decoder (with playback of other formats such as AAC, MP4, M4A, WMA, WAV, MID, OGG) + an FM radio.

*Mouse: ON/OFF. Allows you to enable or disable USB mouse support.
*GMT time zone: to set the time offset, based on the time zone.
= RSF3 Lite =
TMTLOGIC discontinued the RSF3, but continues with . They are now offering the RSF3 Lite, which offers with almost the same features (the ones removed from the original RSF3 were ultimately little used).
