2017-05-23	board complete, generate gerber (x2) fileshardware	Nao Pross	1	-3/+3
	this is probably the last commit before printing the PCB, unless there are some other errors in the board design
2017-05-19	finish wiring and add eurocard compliant standard holes	Nao Pross	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).
2017-05-09	created new layout (starting over)	Nao Pross	1	-3/+3
	the old layout is still under hw/MainBoard1.PcbDoc
2017-05-05	complete wiring for serial interface connector and logic	Nao Pross	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
2017-05-05	add switches datasheets for footprints	Nao Pross	1	-3/+3

2017-04-28	start printed circuit board design	Nao Pross	1	-3/+3
	wired: - clock circiuts - reset button set layout for: - CPU & memory - serial interface
2017-04-13	scheme update and PCB start	Nao Pross	1	-3/+3
	add missing capacitor and resistor values (serial XTAL) create new eurocard standard compliant PCB for the uPC and other minor fixes
2017-04-04	schematic complete	Nao Pross	1	-0/+14
	hw: change address decoder chip from GAL16V8 to M4-32/32 (CPLD) change main bus connector with a custom one (intead of PC/104) start building footprint library
