WDC 65x02 @ 8 Mhz

40-pin DIP package

(Protoype board currently running stable at 2 Mhz. Steps are being taken to stabilize it at 8 Mhz. Worst case if all issues are not solved, the final board could be 4 mhz, but still planning for 8)

40K of "Low RAM"

512K of "High RAM" standard

Expandable to 1 MB, 1.5 MB, or 2 MB by adding additional RAM chips to 3 empty sockets.

128K of Flash ROM

Standard Commodore Kernal

Microsoft BASIC version 2.0

Machine Language Monitor

Can be reflashed from the computer

Four expansion slots with access to CPU databus

Each slot has its own 32-bytes of mapped RAM

8 general-purpose I/O lines available (user port)

PS/2 Keyboard

PS/2 Mouse

Two NES or SNES style game ports (dev board just has pin headers)

IEC compatible disk drive port

Internal SD-2-IEC with SD card slot (on final board only, not dev board)

Audio is still being determined. There are 3 designs being considered and tested at the moment including a Yamaha YM2151, a SAA1099, and a SID-like implementation in the video chip’s FPGA. Which will ultimate work best is yet to be determined.

128K of internal video RAM

640x480 @ 60 Hz analog VGA output

640x240 Composite video and/or S-Video output.

Option to disable color signal for sharper grayscale text/graphics on composite monitors.

80x60, 40x30, and 20x15 character modes

8x8 pixels characters with PETSCII font

16-colors with independent fore/background colors for each character

256-color text mode with global background color.

pixel scaling: 1x/2x/3x/4x for width and height

tile size: width 8/16 pixel, height 8/16 pixels

tile map size: width 32/64/128/256 tiles, height 32/64/128/256 tiles

tile modes: 1 bpp (bits per pixel) with per-tile 16-color foreground/background color, 8 bit tile index (16 color text mode) 1 bpp with per-tile 256-color foreground color, background color is always index 0 (transparent), 8 bit tile index (256-color text mode) 2/4/8 bpp with per-tile h-flip, v-flip, 4-bit palette offset, 10 bit tile index all these modes support smooth scrolling

bitmap modes: 1/2/4/8 bpp 4-bit palette offset these modes don't support scrolling to save on memory

the 1 bpp tile modes in combination with 8x16 tile size will also allow for a standard VGA font to be used
