I replaced it on the seventh
and failed to get 96 megahertz

What place should I put the delay?

Re: Hacking cartridge HP 84/85

Here at last I achieved 12 megahertz with code byte pinTable[] = {2,14,7,8,6,20,21,5}; void setup() { for (int i=0; i<8; i++) { pinMode(pinTable[i],OUTPUT); } } void loop() { for (int i=0; i<=7; i++) { byte b = 1<<i; GPIOD_PDOR = b; } } Here is a diagram and oscillogram 34623.png 2233.png Please tel...
