In autumn 2004 the first CPC SYMBiFACE (also known as "CPC-IDE") was developed by Detailed documentation can be found here: [[Dr.Zed]] with the financial support of [[Octoate]] and [[TolkinProgramming:SYMBiFACE II|SYMBiFACE II documents]]. It was the first hardware solution ever that allowed connection of IDE-harddrives and CF-cards to the CPC with the maximum possible data transfer speed. Technically the CPC-IDE interface was based on the GIDE IDE interface by Tilmann Reh.

* Supports IDE-Harddiscs with up to 128GB * Bigger HDDs or CD/DVD drives support possible with drivers* Simultaneous operation of two harddiscs (master and slave):CPC SYMBiFACE II provides one solution for connecting a total of up to 256GB on your CPC! * Transfer speed of 162KByte/s: That's as fast as copying memory inside the CPC with LDIRan IDE hard disc. In practice (loading FAT16/32 files) the speed is still about 130KB/s ([[SymbOS]]-FAT-driver).* External power supply required: no extra load for the CPC's internal PSU* No timing problems: Interrupts don't need to be disabled during the data transfer with the harddisc. The harddisc You can operate while you play sound or doing other things with your CPC (multitasking etcuse a master and a slave device.). * Traffic activity display via a LED on the board

That's as fast as copying memory inside the CPC [[6128]] and with LDIR. In practice (loading FAT16/32 files) the speed is still about 130 KB/s ([[dk'tronicsSymbOS|SymbOS]] ram extension -FAT-driver).* 512KB rewriteable ROMExternal power supply provided: no extra load for the CPC's internal PSU.

*512 KB RAM extension, which is fully compatible with the CPC [[Image:sf2romman.gif6128|thumb6128]] and the [[Dk'tronics|320px|SYMBiFACE II rom managerdk'tronics]]RAM extension *512 KB rewriteable ROM. You can upload up to 32 ROMs, which are persistent. You can also use the ROM space as an additional RAM extension. ROMs can be switched on or off via switches or via software. *PS/2 mouse connector. This makes it possible to connect wireless and optical mice (PC compatible, therefore inexpensive) to your CPC. *Real time clock, which is fully PC compatible and (as seen on the photo) provides additional 128 byte persistent RAM, which can be used to store config data.

[[Image:Sf2romman.gif|thumb|400px|SYMBiFACE II includes a rom ROM manager software]] [[Image:RM-Info.jpg|thumb|400px|SYMBiFACE II ROManager]] <br> == ROM-Manager == *Under [[BASIC]] you can use [[ROManager BASIC]] to manage all 32 ROMs of the SYMBiFACE II. It can load/save all 32 or one 16 KB ROM. Further you can copy, move, erase, park, unpark or check ROMs. *The simulated ROMs of the SYMBiFACE II can also be handled by a ROM manager which runs under [[SymbOS|SymbOS]]. This tool is needed for allows displaying, loading, saving and deleting of the 32 x 16K ROMs. *The most comprehensive application for the SYMBiFACE II ROM management "[[ROManager|ROManager]]" runs under [[FutureOS|FutureOS]]. It allows you to display the existing ROMs, load or save one or all ROMs, test a ROM, adapt the checksum, copy, paste and delete ROMs etc. <br> == Background ROMs == [[HDCPM]] or [[UniDOS]] are excellent complements to the Symbiface II. [[File:hdcpm.gif|HDCPM booting CP/M Plus]] <br>  == Derived hardware ===== Cyboard === [https://github.com/salafek/cyboard-for-cpc Cyboard] is a SYMBiFACE II clone with embedded Ethernet controller for the Amstrad CPC range of computers. [[File:Cyboard-v1.1.png]] Its Ethernet controller is supported by [[SymbOS]] and by [https://github.com/salafek/KCNet-software-for-Net4CPC KCNet utilities] for CP/M. The Ethernet controller uses 4 I/O ports: * #FD20: MR - Common Register* #FD21: IDM_ARH - Upper 8 bits Offset Address Register* #FD22: IDM_ARL - Lower 8 bits Offset Address Register* #FD23: IDM_DR - 8 Bits Data Register [[Media:Ethernet W5100s ds v125e.pdf|WIZnet W5100S datasheet]] <br> === RSF3 === The [[RSF3]] is a modern multi-function expansion card that integrates a SYMBiFACE II compatibility mode. <br> === Symbiface II Mouse Interface === Dr. Zed, the creator of the SYMBiFACE 2, also built a standalone Interface of the PS2-Mouse part of the SF2. [[File:Symbiface II Mouse.jpeg|500px]] It is compatible with all software which is compatible with the original SF2-Interface. (Patched Arkanoid from [[Nilquader]] for example, or SymbOS or FutureOS). Every PS2 Compatible Mouse Devices (like trackballs, spinners) can be used. When using a USB Mouse, you need a passive adapter usb to ps2. [https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/sf2-maus-symbiface-2-mouseinterface/ Build your own or make a batch of devices for others] <br>
