Talk Of Building A Computer...

<If you're going to try this, I'd suggest starting with something simple <like an adder or a flip flop, or a register. You'd get an idea of what <would be involved with a simple processor. But I think it would end up <being pretty expensive. I have some partial designs for transistor hardware. A flipflop design used for the TX2 required 10 transistors, 22 resistors, 8 capacitors, two inductors and three operating voltages. A register 8 bits wide would require 8 of these plus gating logic possibly doubling the number of components needed. You can now see why early machines were register sparse. FYI I have an article for a TIC-TAC-TOE computer using tubes and Neon lamps and it required some nine 2d21 thyratron tubes and 190 neon lamps(serve as gate logic mostly and two per box for display). This is a very limited fixed logic machine and it required a lot. Allison
