Hello there,
I have quite an extensive knowledge of vintage Apple Macintosh hardware and software dating from approximately the mid 80's to late 90's as I worked as an Apple Macintosh Systems Administrator and Service Technician during that time.
I also still have a fairly large collection of Apple Macintosh computers, software, parts and peripherals, magazines and manuals dating from that time frame as well.
If anyone is interested in Apple computing during that timeframe and needs any help, answers to questions or parts please feel free to drop me a line as I may well be able to help you or direct you to somewhere than can.
I don't really deal with the very early (now highly collectible) Lisa or DOS based machines or the far more recent machines that run OSX but have good knowledge of most things in between.
Good Karma to you all.
