LASER310 FPGA
Welcome to LASER310_FPGA project. This project is an attempt to recreate the once famous VZ300/Laser310 computer in 80's on Altera Cyclone based FPGA boards.
Features implemented:
- MC6847 /w VGA output
- Super high resolution mode (256*192)
- Cassette input/output emu
- Laser310 internal ROM/DOS ROM on flash
- Enable external ROM with onboard switches at runtime.
- VZ200 support
- 256K RAM module
- Buzzer output
- PS/2 keyboard support (Ctrl+F12 to reset).
- 12.5MHz overclock on SW0
- 64x32 Text mode on SW3
- 6847T1 Lower Case characters support. Enabled by GM0 bit at Port $20 (Requires SHRG extension on)
Planned
- Z80 bus on GPIO mapping.
- Floppy emu support
