Universal Serial Interface for Amstrad CPC II (a.k.a. USIfAC II or... THE GOTEK KILLER FOR AMSTRAD CPC! :D) by Ikonsgr is an evolution of his previous Design USIfAC (with which is fully compatible), based on a modern and much more powerful 40pin 18F47Q10@64Mhz 8bit PIC microcontroller, which offers many new amazing features :

• Completely "from the scratch" project,based on a modern 8bit PIC 16F1579@32Mhz MicroController! (all other serial interface projects, use the rather old, expensive and bulky 40pin 16C550 UART chip)
• Very easy to use by only two BASIC commands, INP() and OUT!
• Completely free DIY project, rather easy and cheap to make (total cost for the DIY kit +all extra parts, would be less than 6euros!)
• SUPER FAST loading of many games/programs, DIRECTLY from the PC!(see "Direct Load" function in User's Guide, and here is a list of games already tested and working)
• Easy and fast transfer of dsk images directly to Amstrad CPC disks!
• Easy and fast individual file transfer (check link for 1000's of games extracted from dsk images)directly from/to Amstrad's Disks!
• Equipped with a reset button and a pause switch for Amstrad CPC!
