Editing Multiface (section)

== Models of Multiface ==
Multifaces were released for 8-bit and 16-bit microcomputers, such as the [[ZX Spectrum]], [[Amstrad CPC]] & [[Atari ST]]. Different models had slightly different features.

=== Multiface One ===

The Multiface One was released in 1986<ref name="su2">[https://archive.org/stream/sinclair-user-magazine-047/SinclairUser_047_Feb_1986#page/n104/mode/1up Lambert, John: "Back Up Your Troubles"], Sinclair User, Issue 47, February 1986</ref> for the [[ZX Spectrum]] 48K. It initially cost £39.95<ref name="ys1"/> ({{inflation|index=UK|value=39.95|start_year=1986|fmt=eq|cursign=£}}) and had the capability of saving data to [[cassette tape]], [[ZX Microdrive]], Opus Discovery (an external 3.5&nbsp;inch [[disk drive]]) or Technology Research [[Beta Disk Interface|Beta]] (an interface that allowed 5.25&nbsp;inch and 3.5&nbsp;inch drives to be connected). The device worked on 128K Spectrums, but only if they were put in 48K mode.<ref name="ys1"/> It featured a [[Kempston joystick]] port, and later revisions contained a switch that effectively 'hid' the device from software. Early versions had a [[composite video]] out port<ref name="su2"/><ref>{{cite journal|last1=Frey|first1=Franco|title=Multifacetted Device|journal=Crash|date=March 1986|issue=26|page=86|url=https://archive.org/details/Crash_No._26_1986-03_Newsfield_GB|accessdate=22 February 2018|publisher=Newsfield Publications}}</ref> but this feature was later removed.

=== Multiface Two ===

The Multiface Two was released for the [[Amstrad CPC]] range of computers and had similar features to the Multiface One, but added a button to reset the computer. Control of the visibility of the device was at a software level rather than the hardware switch found on the Multiface One.

=== Multiface 128 ===

The Multiface 128 was released in April 1987<ref>[https://archive.org/stream/your-sinclair-16/YourSinclair_16_Apr_1987#page/n45/mode/1up Advertisement, "Your Sinclair"], Issue 16, page 45, April 1997</ref> for the 128K version of the Spectrum, including the original +2 model. It worked in 128K or 48K mode and it existed in two versions; initially without a 'thru-port' and later, with one, both of which originally cost the same £44.95,<ref name="ys1"/> ({{inflation|index=UK|value=44.95|start_year=1987|fmt=eq|cursign=£}}) but were later reduced to the same price as the Multiface One.<ref name="ys2">[https://archive.org/stream/your-sinclair-79/YourSinclair_79_Jul_1992#page/n43/mode/1up Advertisement, "Your Sinclair"], Issue 79, page 43, July 1992</ref> The 128 introduced the ability to save to the [[+D]] and [[DISCiPLE]] disk systems, but lost its joystick port (the Spectrum +2 already had built-in joystick ports). The device was not compatible with the later Spectrum +2A or the Spectrum +3.<ref name="ys1"/>

=== Multiface 3 ===

The Multiface 3, released in November 1987,<ref>[https://archive.org/stream/your-sinclair-23/YourSinclair_23_Nov_1987#page/n23/mode/1up Advertisement, "Your Sinclair"], issue 23, page 23, November 1987</ref> was designed for the later [[Amstrad]]-made models of Spectrum that the 128 did not support. It existed in two versions; one with a 'thru-port', for £49.95 ({{inflation|index=UK|value=49.95|start_year=1987|fmt=eq|cursign=£}}), and one without, which cost £44.95<ref name="ys3">[https://archive.org/stream/your-sinclair-30/YourSinclair_30_Jun_1988#page/n55/mode/2up 2-page advertisement, "Your Sinclair"], Issue 30, pages 55-56, June 1988</ref> ({{inflation|index=UK|value=44.95|start_year=1988|fmt=eq|cursign=£}}). Both were later reduced to £29.95<ref name="ys2"/> ({{inflation|index=UK|value=29.95|start_year=1992|fmt=eq|cursign=£}}). The main feature of the Multiface 3 was its ability to save to +3 disk, a useful feature for +3 owners who wanted to avoid the long loading times of tapes.

=== Multiface ST ===

The Multiface ST and Multiface ST II were released for Atari's ST computers. They connected to the cartridge port with a wired connector attaching to the monitor port (to generate the interrupt signal when the button was pressed). Far less effective than the earlier Spectrum models and the same as the CPC model, they required the cartridge to be present in order to load saved games. Red, green and blue cartridges have been noted.
