(note: the marking on the board is “1.5K” but every picture online I’ve seen of a real Apple-1 has a 1.2K there. I put a 1.5K on my first (Obtronix) replica though and it works fine. In my experience 1.2K 1/4W 5% carbon comps are a little harder to find than other values.)
From a picture of a real Apple 1.
Carbon Composition (same on pre-NTI and NTI). May or may not be Allen-Bradley, need verification.
Total on board: 1.
