* | board complete, generate gerber (x2) fileshardware | Nao Pross | 2017-05-23 | 1 | -0/+0 |
| | | | | | this is probably the last commit before printing the PCB, unless there are some other errors in the board design | ||||
* | finish wiring and add eurocard compliant standard holes | Nao Pross | 2017-05-19 | 1 | -0/+0 |
| | | | | | | since there wasn't enough space (I should have added the holes before beginning) there are only 4 holes instead of 6 (2 will be cut out since the space is unused). | ||||
* | wiring for 7 segment displays and traces for the remaining CPU signals | Nao Pross | 2017-05-19 | 1 | -0/+0 |
| | |||||
* | new traces for cpu signals and for high address to the MMU / addr decoder | Nao Pross | 2017-05-18 | 1 | -0/+0 |
| | | | | there are also many other minor changes to connect various wires | ||||
* | wiring for CTC (U8) to address bus and data bus | Nao Pross | 2017-05-18 | 1 | -0/+0 |
| | |||||
* | wiring for P4 and P5 (I/O ports) and circuits for CLKs and RST | Nao Pross | 2017-05-18 | 1 | -0/+0 |

* | wires from DB-9 and HDR5x2 connector to MAX214 (U7) and crystal for TL16C550 | Nao Pross | 2017-05-18 | 1 | -0/+0 |
| | |||||
* | created new layout (starting over) | Nao Pross | 2017-05-09 | 1 | -0/+0 |
| | | | | the old layout is still under hw/MainBoard1.PcbDoc | ||||
* | complete wiring for serial interface connector and logic | Nao Pross | 2017-05-05 | 1 | -0/+0 |
| | | | | | | | other changes: - new layout, probably the board will have to be resized to a nonstandard size (currently 2EUROCARD) - new footprint HDR5x2_SOCKET for standard 5x2 flatcable connectors | ||||
* | add switches datasheets for footprints | Nao Pross | 2017-05-05 | 1 | -0/+0 |
| | |||||
* | start printed circuit board design | Nao Pross | 2017-04-28 | 1 | -0/+0 |
| | | | | | | | | | wired: - clock circiuts - reset button set layout for: - CPU & memory - serial interface | ||||
* | scheme update and PCB start | Nao Pross | 2017-04-13 | 1 | -0/+0 |
add missing capacitor and resistor values (serial XTAL) create new eurocard standard compliant PCB for the uPC and other minor fixes |
