Re: Hacking cartridge HP 84/85

Here is the final step
It remains to figure out how to adjust the width of the gap between the seventh bit.
and how to create another synchronous signal of another type on another pin

Re: Hacking cartridge HP 84/85

dragonator
your code doesn't send a signal to the first output
I replaced it on the seventh
and failed to get 96 megahertz
What do you advise to do?
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...

Re: Hacking cartridge HP 84/85

dragonator delayed I did not set
I used the LED code and removed the delay

Re: Hacking cartridge HP 84/85

Finally i got an Teensy
I can't teach him to give a quick signal,
I used your Wonko code,
ports trick (A) (B) does not work
maybe the Teensy has no ports like the Arduino?
