Neuromancer by William Gibson. A brother from another mother (40 years for those of you scoring at home) who I game with (he's the guy you see me playing PGA2K21 with on Tuesday nights) is coming to visit for a week this month. He wants to binge on the Matrix trilogy over a bottle of Crown, so I'm reading Neuromancer as sort of a prequel.
I was 14 when that came out and saw it in the B. Dalton...loved it and was hooked on Cyberpunk moving forward. Devoured Burning Chrome and Mona Lisa Overdrive when they came out, played the computer game on my Apple ][GS over and over.
Though I first got turned on to him from his short fiction in Omni magazine in the early 80's...great stuff and that was great magazine.
If you haven't read Neal Stephenson's Snow Crash, you should definitely give that a read as well...
My favorite story about Gibson was that he was completely computer illiterate, he had no clue what computers were capable of when he wrote his stories, he didn't think what he was writing was that far fetched in parts, he went to purchase a brand new computer in 1985-86 and was shocked at how primitive they were.
