The Final Form!
At last we can unleash the full potential of this board, all features we planned and then some is implemented in this revision. From the stage 2 we have added:
- Irq Handler, with 15 usable prioritized interrupts
- PS/2 keyboard and mouse interface, and also an RTC. All implemented on a controller.
- CF interface header (There was not room for the socket on the board)
- “PC Speaker” header, for the real retro feeling
- Removed the power regulation circuit (trying to find a better solution).
The board from now needs to be given 5v on the power socket.
The board is routed with all updates we have found so far, and will be updated during the end testing of stage 2. The goal is that this will be the last feature update. Anything after this will be fixes.
Here is a preview of the stage 3 board:
