AT&T 3B2 Simulator
|
|
==================
|
|
|
|
This module contains the source for two simulators:
|
|
|
|
1. A simulator for the AT&T 3B2/400 computer (3b2-400 or 3B2-400.EXE)
|
|
2. A simulator for the AT&T 3B2/700 computer (3b2-700 or 3B2-700.EXE)
|
|
|
|
Full documentation for the 3B2 simulator is available here:
