	Commit message (Collapse)	Author	Age	Files	Lines
*	Add datasheets and resources	Nao Pross	2017-11-28	1	-3/+3
\|
*	board complete, generate gerber (x2) fileshardware	Nao Pross	2017-05-23	1	-9/+9
\| \| \| \| \|	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	-3/+3
\| \| \| \| \| \|	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	-3/+3
\|
*	new traces for cpu signals and for high address to the MMU / addr decoder	Nao Pross	2017-05-18	1	-3/+3
\| \| \| \|	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	-3/+3
\|
*	wires from DB-9 and HDR5x2 connector to MAX214 (U7) and crystal for TL16C550	Nao Pross	2017-05-18	1	-3/+3
\|
*	created new layout (starting over)	Nao Pross	2017-05-09	1	-3/+3
\| \| \| \|	the old layout is still under hw/MainBoard1.PcbDoc
*	complete wiring for serial interface connector and logic	Nao Pross	2017-05-05	1	-3/+3
\| \| \| \| \| \| \|	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	-3/+3
\|
*	start printed circuit board design	Nao Pross	2017-04-28	1	-12/+12
\| \| \| \| \| \| \| \| \|	wired: - clock circiuts - reset button set layout for: - CPU & memory - serial interface
*	scheme update and PCB start	Nao Pross	2017-04-13	1	-0/+14
	add missing capacitor and resistor values (serial XTAL) create new eurocard standard compliant PCB for the uPC and other minor fixes
