work in progress

I can't recommend this course enough.

Things I learnt in the first course:

• Week 1: built elementary gates (And, Or, Not, Xor) and variations of DMux, Mux using NAND gates (also learnt a simplistic HDL)
• Week 2: built an ALU, Full Adder, Half Adder, etc.
• Week 3: built 1-bit register using DFF, 16-bit register, Program counter, RAM chip with storage upto 16K
• Week 4: learnt to use Hack Assembly (an assembly language created in this course)
• Week 5: built a CPU capable of running Hack machine code and a Memory chip (with Screen Memory and Keyboard register)
• Week 6: wrote an assembler in python for Hack assembly
