VG64 "vga card" for the C64 - video cart

Hey all - this is a quick preview of my hardware cartridge for the Commodore 64 which creates a second screen. It is a 128K frame buffer which can be accessed via a register in the i/o space or in an 8K bank. Two modes are exposed, a 640x480 monochrome mode and a 320x480 color mode. The color mode is a bit unusual- it's has a lower resolution red channel at 160 horizontal resolution. (The eye is less sensitive to spatial information in the red).

The card fits in a normal C64 cart enclosure- with a cutout for the DB15HD connector.

The main components are a 128K SRAM and a CPLD. No FPGA.
