ZXMATRIX Interface for any ZX Spectrum computer(atleast 48k)
Supports one flashdrive at USB port 2,
this is limited by software (ResiDOS).
Flashdrive can also be a CF,MMC,SD,MS,M2 ect,
ResiDOS supports FAT16, 2GB limit, keep your
flashdrive at max 2GB size, you won't fill it
anyway, smaller size more speed.
You can use a multi-reader with one card inserted
at time with latest VDIP device software.
I think most people will use a USB memorystick,
they are easy to connect to a pc.
In CF mode, ZXCF or ZXCF+2 ResiDOS versions is used.
In USB mode, ZXUSB ResiDOS is used.
CF socket in this mode is still unsupported.

Future of ZXMATRIX Interface
This is the best part, what can be done ?
Keyboard, Mice, Webcam, Ethernet, Printer, Floppydrive.
we need some application programmers...
VDIP1 FW has a filesystem but after some
investigation the conclusion was that it does
not fullfill our needs, ResiDOS is to run it's
own filesystem. This opens more doors, later on
support for more than one drive on USB is possible.
