As a MINIMUM requirements guideline your Personal Computer should have the following;

1. Windows '95 or '98 Operating System
2. 486 Processor (Pentium preferred)
3. 15" SVGA Color Monitor
4. 101 Keyboard
5. 16MB RAM
6. 20MB Free Hard disk space
7. 3-1/2" Floppy Drive
8. CD ROM Drive
9. 9600 Baud Modem
10. 1 available RS-232 Serial Port (Com1, Com2, Com3 or Com4)
11. Bus Mouse*

* a Bus Mouse is preferred because you'll need 1 serial port for your Modem and 1 serial port for the AMACS RS-485 system. A serial mouse steals one of these ports and makes configuration more difficult, although not impossible.
