FPGA development board dedicated for the implementation of various gaming computers (primarily ZX Spectrum).
- FPGA: EP2C8Q208C8N
- Microcontroller: STR755FV2T6 (or STR750FV2T6)
- Memory: SDRAM 16 Mb K4S281632J-UC75 (or 32 Mb K4S561632J-UC75)
- RTC: DS1338Z-33 +
- Slot for SD card
- Two PS/2 ports (keyboard, mouse)
- 2 ports for joysticks
- USB - virtual com for debugging and programming the microcontroller
- Video: three R-2R matrixes, 8 bits each (output to VGA, Composite, S-Video)
