This MS Windows version can be downloaded with no restrictions (requires Microsoft.NET Framework 4): lmc.net.zip (version 3.3).
There is also an installation guide for a lmc.exe version that might be more suitable for school networks.
- Loads and saves assembly language programs as text files.
- Supports labels for both branching and data.
- Supports indentation making code easier to follow.
- Does not remove the original code when assembly takes place.
- Features both a STEP and a RUN mode and the ability to switch between them while a program is running.
- In STEP mode, the ‘Little Man’ explains the next instruction before it is executed.
- Allows assembly language programs to be pasted directly into the program window.
- Allows programs to be copied from either text window for use in reports.
- Run mode is faster than the atkinsn.yorku.ca version.
- Allows line annotation such as: loop LDA value1 // Start of main loop.
- Produces an assembly language version without labels or annotation, makes it easier to understand the assembled code in RAM.
- INPUT is via an ‘input device’ rather than the keyboard, allowing integer values in the range -999 to 999.
- Multi-line output makes it easier to follow programs that have more than a single output.
- ‘Machine Code’ instructions in RAM can be edited directly (the U button will update any changes to the current instruction).
- version 3.3 – RESET button added making it possible to reset the program counter without having to assemble the program again.
- version 3.2 – improved line annotation facility, any annotation can be added to the end of a line.
- version 3.1 – implemented negative DAT and INPUT values.
- version 3.0 – ASSEMBLE button altered to more accurately reflect what it does.
- version 2.9 – set the overflow of numbers less than -999 to match the atkinsn.yorku.ca version
(if accumulator < -999 Then accumulator = accumulator + 1999). Note, some LMC versions store negative numbers using the 10’s complement of the number and don’t allow negative numbers to be stored as such.
- version 2.8 – swapped the positions of the INPUT and the OUTPUT to aid data entry.
