I got mine somewhat late- in '86 after starting on the ZX81, Ti99, and then the 800XL before then. Besides, I nuked the 6520 in the 'XL trying to build a ring-detect.
The world that existed on the other side of a 300 baud modem really made me wish I had a 64 until I found one with a 1541 and a spare Vic20 at a garage sale for $35.
Then I worked that summer for a 1670, a printer and another 1541.
Happy Birthday
