Title: Amiga 500 enter and return keys don’t work
Post by: scm2000 on June 17, 2024, 11:30:36 PM

im working on my Amiga 500. with a multimeter i measure 5 volts at the keys respective Y row pins on the keyboard ic when they are pressed. so i believe the switches are working

i replaced the keyboard pcb with a reported working one to rule out a problem with the keyboard ic and other electronics.

i swapped the cia chips to try to rule that out.

the system has an adram 540 ram expansion. i can try pulling that completely out.

but what should i check next?
