ZXMATRIX Interface for any ZX Spectrum computer(atleast 48k)


Details(USB): 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. Software details: 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. ZXMATRIX common Technical details: Blue PCB color, base pcb size 70x54mm 1MB memory as standard (one chip) New memory backup solution Jumper selected mode USB/CF (only changes memorypage I/O from 16 to 8bit I/O) 1 ZXBT3 socket for eg. +2upg. module / ZXUSB module ZXBT3 connector is compatible to ZXBT2 modules (ZXBT2 can't use ZXBT3 modules) ZXMATRIX, (USB mode) Technical details: USB host controller Vinculum VNCL1 8/32 bit V-MCU Core Dual DMA 64k Embedded flash program memory 4k internal data SRAM USB 2.0 slow/full speed 2 Type A USB sockets Debug mode jumper Teoretical transfer speed is 202.5K/sec ZXMATRIX, (CF mode) Technical details: 1 High speed CF socket Teoretical transfer speed is >200K/sec (ZXMATRIX has been adapted for the +2upg module, no wires) More ZXMATRIX Interface details 2 Pcb's (VDIP1 is not counted) 1 USB VDIP1 module (contains alot parts) 8 74HCT logic chips 1 memory SRAM chip 19 diodes 12 caps 15 resistors 1 led 1 cf socket 1 cr2032 socket 1 cr2032 battery 39 jumper pins 3 jumpers (hats) 1 26 way female connector 1 edge connector Future of ZXMATRIX Interface This is the best part, what can be done ? Keyboard, Mice, Webcam, Ethernet, Printer, Floppydrive. we need some application programmers... Additional notes 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.
