Is anyone familiar with the 74161 counter chip at location C5? It is said to deal with the Non maskable interrupt pin on the cpu, and I'm wondering what it's function is, and whether it can be manipulated to effect game speed.(Scoring rate).
Also did all Asteroids PCBs by default come with a 12.096 crystal?
Thanks.
