I remember dialing up to a BBS in the area in 1990 that had 4 phone lines. That was amazing at the time when most BBS only had 1 line.
But I do remember downloading text files FILE.IDZ about other BBS, and reading some magazines that mentioned other BBS systems that had 32 and more phone lines but you had to pay. That seemed like it was just on another level in another part of the world that seemed like fantasy compared to the area I was in.
