I used to run an 8-line BBS (Fidonet mail hub) on a single 486DX2-66 machine with 8MB of RAM under OS/2 2.11 back in 1993-97. I often played games or used C compiler at same time. This same machine also was a local LAN server (running IBM LAN Manager), serving files to tens of other machines on 10Base2 coax ethernet in the office. Somewhere about 1996 we got a leased line internet connected directly to this same box over a serial line, the machine became an IP router and a remote access server allowing premium BBS users to run PPP/SLIP connections. That's how I got involved into ISP business. :-)
