Schematic incomplete? #1

Open GravisZro opened 7 months ago

GravisZro commented 7 months ago

So, I was looking at the kicad project schematic and either I'm not understanding something or there schematic isn't complete.

Specifically, I am looking at several of the 74151N symbols which I believe is a 1 of 8 Line Data Selector/Multiplexer but most connected to the W[0..7] bus have the selection lines (A,B,C,G) completely unconnected. I'm also noticing the RAM modules don't have any address or data lines connected.

Is the schematic incomplete or am I somehow interpreting it incorrectly?

Side note: you should use multiple pages to better organize the schematic.

yes they are incomplete. any questions let me know

I have no specific questions but I hope you will complete the schematics so that people can actually build a sol-1 computer. With completed schematics it should be fairly easy to make a complete PCB layout.
