• 480 MHz 2-core processor.
• USB port for storage.
• USB port for mouse (Multiplay).
• microSD port for system and settings.
• 2 slots for MX4 cards (DC3 connector).
• MP3 module + FM radio (equivalent to an MSX SE-One card).
• Output for FM radio antenna.
• Headphone & microphone input/output for VOIP.
• MIDI audio input/output.
• 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.

Parameters available during the initialization

• Activation of a chime at startup: ON/OFF.
• Pen sound on touch screen: ON/OFF.
• Activation of the integrated 2 MB memory expansion: ON/OFF.
• Function that can be deactivated if an application or game is not compatible.
• Or if you want to use another memory extension on an MX4 slot. Warning: do not activate the integrated 2 MB memory extension of the RSF3, at the same time as another external memory extension on an MX4 slot.
• 464 Memory hack: ON/OFF.
• If RSF3 is used on a CPC 464, use the patch by @ToTO to take into account the memory extension.
• 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.
• Symbiface II: ON/OFF.
• Allows you to activate or not the compatibility mode with the Symbiface II.
• Multiplay 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.

Miscellaneous

The RSF3 also contains the following elements:

• Emulation of older interfaces like the SSA-1 speech synthesizer, the Amdrum, and the Digiblaster. With programs for each of these interfaces to use them.
• A "System Information" application which summarizes the detailed information of the RSF3 (firmware version, Wifi and network information, activated rombank and list of roms with their positions, the activation status/or not of the M4, the SE -One, CPC 464 hack, Multiplay, SF2, etc.
• A drawing application for the stylus.
• A “Post-it” application to write whatever you want, like a memory aid.

The 2 MX4 slots are more than sufficient given that with the RSF3 you don't need to have as many as a Mother X4 given that it already includes:

• a 2 MB memory extension (can be deactivated if necessary): no need to add another one.
• 255 rombanks: no need to add 1 rombank.
• M4 Board emulation: no need to add the card of the same name.
• Hacker v7.0 in a dedicated rombank: no need to add the card of the same name.
• support for a USB mouse: no need to add a Multiplay or an Albireo.
• an RTC clock: no need to add a Nova extension or equivalent.
• emulation of old audio devices/cards, etc.

Development team

The TMTLOGIC team around RSF3 is very active. It regularly offers new features, applications, and firmware updates. Through a very efficient SLACK network dedicated to SF3 / RSF3, all users communicate regularly with each other, share information and solutions, and contribute to developments and future evolutions.
