I got extremely lucky that my parents bought me an Atari 800XL, XF551 drive, XM301 modem and Okimate 10 at Federated in Bakersfield, CA in 1985/86.
They didn't let me use the modem, but I did get the occasional magazine, and I remember getting these shareware catalogs on floppy in the mail, then I'd print an order form and use my allowance to buy various bits of shareware via the mail.
