What (wiki?)books can I purchase that would help me bridge my mental understanding of computer circuitry from 'this is a circuit with a resistor and a power source and a lightbulb, while this is a CPU that has wires to memory and magic happens to make em talk' to 'I know the difference between TTL logic and a microprocessor and can fuzzily trace where the electrical signals go'?
I don't own but am aware of things called logic analyzers, 'progammers', and the difference between a microcontroler and a microprocessor (ish, the former is vaguely a system on a chip?), but I'm not sure where to start to fill in the many gaps in the bits of knowledge I have so far.
Wikipedia feeds me articles about logic gates, programmable logic, and Algorithmic Logical Units used in things like the Xerox Alto, but I don't know if this means I should try for electrical engineering courses or something simpler?
