*	finish wiring and add eurocard compliant standard holes	Nao Pross	2017-05-19	178	-55/+790
\| \| \| \| \| \|	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	54	-6/+56
\|
*	new traces for cpu signals and for high address to the MMU / addr decoder	Nao Pross	2017-05-18	27	-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	17	-3/+3
\|
*	wiring for P4 and P5 (I/O ports) and circuits for CLKs and RST	Nao Pross	2017-05-18	6	-3/+3
\|
*	wires from DB-9 and HDR5x2 connector to MAX214 (U7) and crystal for TL16C550	Nao Pross	2017-05-18	33	-6/+6
\|
*	created new layout (starting over)	Nao Pross	2017-05-09	73	-130/+1039
\| \| \| \|	the old layout is still under hw/MainBoard1.PcbDoc
*	complete wiring for serial interface connector and logic	Nao Pross	2017-05-05	97	-15/+20
\| \| \| \| \| \| \|	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	13	-17/+17
\|
*	start printed circuit board design	Nao Pross	2017-04-28	158	-31/+11374
\| \| \| \| \| \| \| \| \|	wired: - clock circiuts - reset button set layout for: - CPU & memory - serial interface
*	scheme update and PCB start	Nao Pross	2017-04-13	51	-109/+1787
\| \| \| \| \| \|	add missing capacitor and resistor values (serial XTAL) create new eurocard standard compliant PCB for the uPC and other minor fixes
*	schematic complete	Nao Pross	2017-04-04	131	-98/+214
\| \| \| \| \| \|	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
*	added iospace address decoder	Nao Pross	2017-03-31	17	-12/+12
\|
*	changed scheme layout	Nao Pross	2017-03-23	119	-13/+189
\| \| \| \| \| \| \| \| \|	hw: changed scheme and annotated components doc: added build script for windows sw: added res/ folder with blaster and created jedec document for address decoder pld
*	hardware nearly finished	Nao Pross	2017-03-17	339	-125/+850
\| \| \| \| \| \| \| \| \| \| \| \| \|	doc: added datasheets for - GAL16V8 - MAX214 - MAX232 added script to build doc under windows with miktex updated notes hw: finished i/o devices and bus viewer sw: created files for pld programming
*	hw: moved everything to one sheet	Nao Pross	2017-03-06	226	-57/+662
\|
*	doc: added L7805ACV datasheet; hw: updated scheme	Nao Pross	2017-03-05	6	-13/+1275
\|
*	hw: created library project, doc: added 74LS193 datasheet	Nao Pross	2017-02-24	17	-464/+5
