| * | Work in progress. Added PS/2 keyboard interface, hardware debugger. ↵ | Mike Stirling | 2011-07-29 | 1 | -71/+186 |
| | | | | | Interrupt test output to 6522 (remove later). Fixed error in pin assignments that blocked access to Flash chip select. Added reading sideways ROMs from external Flash (all but BASIC masked off for now). | ||||
| * | Boots to "BBC Computer" message with dummy keyboard and interrupts disabled ↵ | Mike Stirling | 2011-07-25 | 1 | -50/+113 |
| | | | | | (something is keeping the interrupt permanently asserted). Need to add paged ROMs in Flash (no more room in the FPGA). | ||||
| * | Work in progress: Added MOS6522 from www.fpgaarcade.com. Added simple_uart ↵ | Mike Stirling | 2011-07-17 | 1 | -14/+313 |
| | | | | | component in "FRED" for test purposes and added alternative EHBASIC ROM for debugging | ||||
| * | Fixed SRAM routing logic | Mike Stirling | 2011-07-16 | 1 | -2/+16 |

| * | Added top-level, PLL, MOS ROM and CRTC. CRTC seems to behave strangely ↵ | Mike Stirling | 2011-07-16 | 1 | -0/+563 |
