Another nostalgia trip: CoCo on a Chip, or How to build a matchbox CoCo. It uses a Terasic DE0-Nano FPGA board and a couple of daugtherboards (NanoMate, NanoLog). Add a plastic case and you are almost done.
then you just need the files you can download.
- PS/2 keyboard
- PS/2 mouse (if you donít have a real CoCo joystick)
- VGA monitor or VGA-capable TV
- 1/8″ male to male stereo audio cable for amp or TV input
- FAT32 SD card with your favorite CoCo .dsk images and OS-9 images.
So what kind of CoCo do you get for this?
- The most accurate and capable all-hardware Tandy Color Computer 3 clone available.
- Very compact, cool running temperature
- Employs Greg Millerís cycle-perfect 6809 core with .89, 1.79, 3.58, 7.16 Mhz rates.
- 1MB of RAM
- VGA port
- 512 colors
- Up to 640◊480 resolution
- Up to 80◊60 full color text
- Double height of any graphics/text mode
- HQ stereo sound jack for all audio generated by the system, 8 to 12 bits of precision per speaker.
- PS/2 keyboard and mouse ports
- SD card virtual disks/drives are also mapped to the FDC for high compatibility with floppy-based software.
- Cassette deck support
- Two dual-button joysticks
- Smart hi-res joystick/mouse circuit lets you run ColorMax Deluxe, CoCoMax III, gshell, etc. using your PS/2 mouse without having to toggle any switches.
- A/V digitizing support
- 40-bit fixed-point FPU
- Halt / no-halt GPU draws super fast lines, boxes, filled boxes, memory copies and memory fills.
- WIFI and bluetooth serial capable.
- CoCoNet bluetooth disk drives from DOS or OS-9.
- Reprogram the 8266-01 WIFI module using the Arduino IDE and other flashing utilities, over bluetooth!
- Runs OS-9/NitrOS-9 and Sock Master demos like a boss.
