Quoted from Cheddar:UPDATE: moved the test rom to U27 and the LED is blinking. 7 segment still blank. I'll repopulate the PIAs and test it out.
Any suggestions on the LED not working? UPDATE: Put the PIAs in and the LED works as well
Thanks
Was just going to say, the PIAs need to be there for the 7-segment display to work because the code for the control of it is on the EPROM, and it runs through the display PIA....I think. I'm kinda fuzzy today, but I'm pretty sure that is how it works.
