that's where I started....
DR-DOS
10 MB HD
360K floppy drive (5 1/4")
Amber monitor
8Mhz TURBO, 8088 machine.
I ran a WWIV BBS for years on a 1200 baud modem
upgraded to Win31. on a 286 with a 9600 baud and 3 1/2" cunchy drives
then to a 386SX, and finally to a pentium (586) with a 14.4 modem.
Started WWIV in Turbo PASCAL, converted to C and then C++.
Was part of an international network of WWIV systems... my computer auto-dialed Califonia once a night to pick up packets and then acted as the local area hub from 1-5 am as everyone else auto-dialed to grab their packets and so on...
It wa a remarkable piece of logic to handle the routing of that stuff.
