I found this once while reading up on the Hacker brand of Radios once popular in the UK. It's a 33rpm 7-inch flexi-disc. It's a garage rock band;s only release that was pressed in 1988 in Japan. It usually goes for about $15. I keep being temped because of that great name. But in 1988 the word "hacker" didn't have the common use it has today. By 1995 there was already a Hackers Guide to Project Management, in 1996 there was already a Hackers Dictionary by Eric Raymond in print. By comparison 1988 was cutting edge but the Hackers Handbook was written by Hugo Cornwall. So it was in use at least in casual slang.
