To start off this forum I thought I'd tell everyone my problems with my Apple-1 Replica, so I recently just finished my Apple-1 replica I believe in November 2020, and all I had left to add was PROMs and a 2519.
In late December 2020, I got my PROMs and a 2519 and so upon initial boot up I wasn't getting 40x24 character display on the terminal display. I get the flashing "-@" symbols and such like normal. But only half of that screen is being displayed, the rest the screen displays flashing "@" symbols from top to bottom but not on the thin left and right side borders of the screen. It's kinda hard to explain.
I'm gonna try to add some photos, I have some MINIMAL spare parts:
-5300uF 15V Cap
I also just ordered these, they should be here soon.
-1 New DS0025
-5 New 74161s not (As)
-2 New 74157s
-10 New 1404As
Hopefully this helps! Any questions, ask away?!
P.S. I slowed down this video so everyone could see it.
