Don't forget core memory and early 1024x1 Dynamic rams. :)
Fun to interface.

Design - Design - Design
I think I'll go for the BIG CPU DESIGN --- A simple 24 bit CPU.
So I will need the book, 14 74172's and 8 74F382's.
Now if I could only drop the ALU logic since I have alot blinking
lights and strange data paths. Since my goal is about PDP-8 speeds
I don't think I will have a problem using LS parts.
