Wel I voted for '88, but it must have been earlier, perhaps '87. My parents purchased a 520STFM Super Pack, at the time in the UK for £399.99 if memory serves. So I am guessing Christmas '87 for the Super Pack. Best Christmas present I ever received, but for that I had to sell my Atari 800XL. That wasn't easy, because I remember I swapped my 800XL with my neighbour who worked at a model shop for a Tamiya Frog radio controlled beauty. I had to beg my neighbour to swap the Frog back for my 800XL because I missed it, then begged my parents for an ST, but had to sell the 800XL to help them. Still have the same STFM, upgraded over the years which first was a games machine, then music machine, served me through college using Papyrus and Atari Works. It is still set up to this day now in my little music studio, never once has it been resigned to the loft.
My first PC wasn't until 2004.
However this has got ne thinking about how many packs there were for the ST, and when they were released? I guess I'm talking from a UK perspective. If memory serves there were the following which came in both STFM and STE guise in some instances:
Family Curriculum Pack
Discovery Extra Pack
Family Curriculum II Pack
Atari Falcon 14mb, 68882, Dual 8gb CF & Steinberg FDI
Atari Jaguar, Rotary controller, Skunkboard & Cat Box
Atari 520STFM 4mb, TOS 2.06 switcher, OverScan, GigaFile, PARCP-USB, Unicorn-USB, System Solutions MiniS HD, SyQuest drives, ICD Link II, PhatBoy MIDI Controller, Philip Rees 5M MIDI merge box, Soundpool M04, Steinberg MIDEX, SMP II, Emagic Log 3, C-Lab Unitor 2, Combiner & Export expanders
