	Commit message (Collapse)	Author	Files	Lines
2017-05-23	board complete, generate gerber (x2) fileshardware	Nao Pross	5	-21/+21
	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	4	-12/+12
	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).
2017-05-19	wiring for 7 segment displays and traces for the remaining CPU signals	Nao Pross	2	-6/+6

2017-05-18	new traces for cpu signals and for high address to the MMU / addr decoder	Nao Pross	1	-3/+3
	there are also many other minor changes to connect various wires
2017-05-18	wiring for CTC (U8) to address bus and data bus	Nao Pross	1	-3/+3

2017-05-18	wiring for P4 and P5 (I/O ports) and circuits for CLKs and RST	Nao Pross	1	-3/+3

2017-05-18	wires from DB-9 and HDR5x2 connector to MAX214 (U7) and crystal for TL16C550	Nao Pross	2	-6/+6

2017-05-09	created new layout (starting over)	Nao Pross	6	-15/+29
	the old layout is still under hw/MainBoard1.PcbDoc
2017-05-05	complete wiring for serial interface connector and logic	Nao Pross	5	-15/+15
	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	5	-15/+15

2017-04-28	start printed circuit board design	Nao Pross	5	-24/+24
	wired: - clock circiuts - reset button set layout for: - CPU & memory - serial interface
2017-04-13	scheme update and PCB start	Nao Pross	5	-12/+26
	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	6	-12/+40
	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
2017-03-31	added iospace address decoder	Nao Pross	4	-12/+12

2017-03-23	changed scheme layout	Nao Pross	4	-12/+12
	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
2017-03-17	hardware nearly finished	Nao Pross	5	-12/+54
	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
2017-03-06	hw: moved everything to one sheet	Nao Pross	2	-9/+23

2017-03-05	doc: added L7805ACV datasheet; hw: updated scheme	Nao Pross	1	-3/+3
