This is currently very much "work in progress".
Initial version
First "working" version features:
- Z80A CPU
- 8 MHz clock
- 8K rom (eeprom)
- Contains the software that is ran in the start up. Currently only writes the information text to the top of the screen.
- 56K ram
- Currently used only as video ram.
- VGA adapter
- 400 x 240 pixels
- monochrome
- no input device
Future plans:
- New VGA adapter with 640 x 480, 256 colors
- I have decided to do this with FPGA as using "old school approach" would become too complex and expensive. For this I need to learn Verilog/FPGA design.
- Homebrew keyboard
- SD card support
