[[Image:%3Fattach%3D34008;image.jpeg|thumb|USIfAC II]]The Universal Serial Interface for the Amstrad CPC '''U'''niversal '''S'''erial '''I'''nterface '''f'''or '''A'''mstrad '''C'''PC (USIFACUSIfAC), currently in version 2 (Styled USIFAC USIfAC II), is a modern serial interface based around a PIC microcontroller designed and built by [[ikonsgr]] from the CPCWIKI Forums. Project's Main Thread:- https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/usifac-iimake-your-pc-or-usb-stick-an-hdd-for-amstrad-access-dsk-and-many-more!/There is also a special thread for technical problems & support: https://www.cpcwiki.eu/forum/hardware-related/usifac-ii-technical-problems-support/
The only chip on the board is the 18F47Q10 PIC. The PIC software is written in Great Cow Basic and has been released by [[ikonsgr]].
The board allows for TTL serial output and connection to a USB Stick as well as a ESP8266 WIFI module.
The board has been used for many purposes including:
{| class="wikitable"
|-
| • Run games/programs from a usb stick or PC Hard Drive (through ESP8266 WiFi module or UART serial cable).Save is also supported, as well as full access to ASCII files too.
|-
| • Full read/write access of DSK images of both AMSODS and PARADOS formats.
|-
| • Very fast loading speeds of up to ~30kb/sec (more than 6-7 times faster ,than a usual speed of a gotek/floppy disk drive).
|-
| • Access up to Four DSK images and choose them "on the fly", to support all multi-image Games.
|-
| • Load SNA snapshot files.
|-
| • MIDI, RS232 and accessing online BBS.
