The thing that truly changed my life was the Commodore Reference Guide, with schematic, and a book from Data Becker that described the schematic in low level detail. Address decoders, chip selects, tri-state data busses…

I had been reading Elektuur (Elektor for English readers) for years, but never quite understood how computers worked.

That book changed everything, like a giant light bulb switching on. Suddenly I could read all those digital schematics. Digital design was what I wanted to do in life. And I did and still do.
