\| \| \| \|	This is a minimum viable PDP-8 that can print "Hello, world!" and halt.

\|
*	Properly quote quartus_pgm commandline.	Julian Blake Kongslie	2021-04-15	1	-1/+1
\|

\|

\|
*	Ignore various artifacts of quartus build.	Julian Blake Kongslie	2021-04-14	1	-0/+12
\|

\|
*	Add UART receive opbit.	Julian Blake Kongslie	2021-04-07	4	-4/+38
\|
*	Switch back to $past-based scheduling; my clever idea wasn't clever enough.	Julian Blake Kongslie	2021-04-07	4	-101/+74
\|
*	Don't rebuild verilator just for memory file changes.	Julian Blake Kongslie	2021-04-05	1	-2/+3
\| \| \| \|	(These files are read when the simulator starts, not when it's built)

\|

\|
*	Assembler errors for too-far jumps.	Julian Blake Kongslie	2021-04-05	1	-0/+2
\|
*	Change our simulator timing model to use continuous assignment guards.	Julian Blake Kongslie	2021-04-05	4	-86/+113
\| \| \| \| \| \| \|	Instead of depending on verilator getting $past right, this (ab-)uses the SystemVerilog scheduling model which allows us to get a consistent view of the universe by "isolating" the blocking updates. Easier to code to and seems to be more reliable in verilator.

\|

\|
*	Change build system so verilator doesn't require constant "make clean"s.	Julian Blake Kongslie	2021-04-05	2	-3/+7
\|
*	Remove idx, add indirect jumps, renumber opcodes so NOP=0, add absolute ↵	Julian Blake Kongslie	2021-04-04	3	-117/+133
\| \| \| \|	labels to asm.rb
*	Add indirect memory operations.	Julian Blake Kongslie	2021-04-04	3	-8/+34
\|

\|

\|

\|

\|
*	Trivial assembler.	Julian Blake Kongslie	2021-03-29	2	-10/+71
\|
*	Trivial cleanup of initial memory image.	Julian Blake Kongslie	2021-03-29	1	-2/+1
\|
*	Convert to using $sampled instead of $past, for more uniformity.	Julian Blake Kongslie	2021-03-29	3	-13/+9
\|
*	Fix WIDTH warnings from verilator.	Julian Blake Kongslie	2021-03-29	2	-6/+9
\|
*	Vastly improve the edit-rebuild-debug cycle.	Julian Blake Kongslie	2021-03-28	1	-0/+7
\|
*	Possibly slightly less lame.	Julian Blake Kongslie	2021-03-28	1	-10/+10
\|
*	Yet another lame attempt.	Julian Blake Kongslie	2021-03-28	2	-34/+71
\|

\|
*	Use a separate memory module.	Julian Blake Kongslie	2021-03-28	2	-9/+110
\| \| \| \|	Hopefully this will infer a memory the way we want in Quartus.
*	Some more interesting opcodes.	Julian Blake Kongslie	2021-03-28	3	-24/+62
\|
