x86 Microcontroller Simulator for students of low level programming
This is a Microcontroller Simulator based on the x86 architecture intended for
students learning low level programming for the first time. It is written for both
Windows 3.1 (16 bit) and for Windows95/98/NT (32 bit).
The simulator is based on the low eight bits of the 8086 chip. It can be single
stepped or continuously run. The CPU registers, and RAM contents are made visible.
The simulator is programmed in 8086 like assembly code. This is assembled into
machine code that is not the same as 8086 code.
It is possible to control simulated traffic lights, seven segment displays, a heater
and thermostat, a stepper motor and a snake in a maze. CALL, RET, INT, AND IRET are
available in the registered version. Serious programming problems like multiplexing,
procedures, parameter passing, interrupts and recursion can be tackled.
There is on-line help stored in a Windows Help file. The help pages can be word
processed and printed. There is a MS Word 2 version of the on line help.
This upgrade from V2.2 fixes bugs and irons out some problems in the user interface.
