Had a friend lived across the street from me in 85 when I had my first Jr, bought new at Computerland in Houston, Tx.
If I remember correctly the COCO and Commodore 64 was the biggies for the BBS crowd.....
I had my BBS, written in Basic running on my Jr with two Floppies...
and a 1200 Baud HAYES modem ($400 new) yikes.. but wow the speed step up over 300 baud..
Loved that busssss.....chirp connect sound of someone calling into the BBS and downloading some 34K utility I had on Floppy drive #2.
and it only took 10-20 minutes to download

(is this what they call midlife crisis) I think I'm late !!
