After finishing my "One Game a Month" challenge in 2014 I got back to my plan to learn (again) some electronics and I'm building a AVR based 8-bit 80s style microcomputer.
On January I got the video driver (composite video, PAL; rendering from external SRAM) and the keyboard driver (PS2).
Reading and learning about PAL and PS2 has been very interesting, and also I had to learn a EDA software (KiCad) to keep the schematics safe because the Arduino board has now more cables that I can safely track ;)
Besides I had to understand lots of details about the AVR, mainly how SPI and the USART interfaces work.
