Que es esto?

Es básicamente una interfaz de ROM externa con una ampliación de memoria e interfaz de joystick.

¿qué utilidad práctica tiene?

MEMFACE = universal memory expansion interface
- multiface 1
- multiface 128
- multiface 3
- divide memory 512kB-1MB (if you connect original divide then MEMFACE increase memory size of DIVIDE to 512kB ram+512kB rom)
- mb02 memory 512kB-1MB (this mode enable 16kB rom switching, allram modes and testing 16kB roms/IF2 games, flashing rom chip,run system BS-DOS from MB02+ interface, etc...)
- zx rom replacement (can use any other 16kB/32kB or 64kB roms as replacement of internal ZX rom)
- rom emulation in external sram
- own NMI(MAGIC) and RESET buttons (NMI can jump to BIOS menu with setup)
- multijoystick support (support all popular contoll keys and joystick modes)
- allram mode support (can be used for test own 16kB zx rom images or in future for CP/M)
- rewritable flash eprom memory (flash utility exist)

How works the ram expansion on +2AB/+3 ?

Work identically as on all other ZX models. +2A/+3 rom can be replaced with your own rom, for example +3e, or with original ZX128rom or 48rom (for better software compatibility). MEMFACE on +2A will work as MULTIFACE 3, MULTIFACE 128, DIVIDE memory, MB02 memory,etc... Memface also enable connection of old zx interfaces which originally not work with +2a/+3 models (MEMFACE convert external /ROMCS signal from external devices to two /ROMOE signals). I plan add also multiswitching support (possibility fast switch between more 128kB tasks).

Interesting
