Well one thing the 80's had was Byte Magazine. I wish it was still going and was due a month themed on Raspberry Pi. There just does not seem to be any good in-depth technical magazines any more.
Byte lives! http://www.informationweek.com/byte/
It's not what it once was, but, it does have some usable content. It was never really big on details like Kilobaud Microcomputing and platform-specific magazines and newsletters, but, there is info out there. There are a couple of on-line Pi periodicals trying to get organized, but, until developers and hard-core hobbyists get their hands on boards for a significant amount of time, it will be a waiting game. However, there's not much money to be made trying to sell detailed information once it's been put on the WWW for free, so, don't expect to see the kinds of technical content-intense magazines we grew up on decades ago anytime soon.
The best things in life aren't things ... but, a Pi comes pretty darned close!
