== Introduction ==

[[Image:Ulifac_1.jpg|thumb|ULIfAC v6]] [[Image:Ulifac highres.jpg|thumb|ULIfAC v6 with [https://www.thingiverse.com/thing:6035835 3D case]]]

The '''Ul'''timate '''I'''nterface '''f'''or '''A'''mstrad '''C'''PC (a.k.a. ULIfAC), is a modern multi function board that you can plug to a real Amstrad CPC 464 or 6128.

It offers '''the 3 most important functionalities''' (especially for CPC 464):

* Browsing directories and loading from plain files, dsk images, snapshots from a USB stick or a PC via a serial cable or WIFI
* Ram Expansion
* Rom board

...'''in a SINGLE board''', something unprecedented before ULIfAC appeared (and if i'm not mistaken still is...), and also in such low price.

== More details ==

The ULIfAC is based around PIC 18F47Q10 Microcontrollers, designed and built by [[ikonsgr]] from the CPCWIKI Forums. ULIfAC is an evolution of [[USIFAC|USiFAC II board]], with which is 100% compatible.

The USIfAC II board offered Mass storage access at a very low price too.

'''ULIfAC''' board expands the functionality of the previous USIfAC II board, by offering many new features on the same board:
