What am I missing from this simplified Apple I motherboard map?

Posted by: Huxley on 2025-02-15 17:03:13 I'm working on a presentation for some upcoming Retro Roadshow events, and on one slide I want to quickly summarize the major components of the Apple I motherboard. Other than the big capacitors in the top-right quadrant, what am I missing currently that is noteworthy or worth calling out, and/or do you see any goofs in my current version? Thanks in advance for any suggestions! Huxley

Memory you should "un circle" the left most 2 chips, and add in the 8 chips directly above. The 16 chips in the 2 rows left of the expansion slot and right of the 75154 are all RAM. Many of the other ICs in rows C/D are for the terminal section. Depending how detailed you want to go this site has a great interactive breakdown https://www.apple1registry.com/interactive/apple-1.html
