Download demo version of SIM51
Click here to download the demo version of SIM51 ('lhasim31.exe' - about 100 KBytes). But First, please read instructions to install the demo version of SIM51.
To install demo of SIM51 :
Create a directory on your hard disk (e.g. C:\SIM51) and copy the file LHASIM31.EXE in it. To install the demo version, just run LHASIM31.EXE from the DOS prompt. It will explode and create many other files. It includes SIM31.EXE i.e. the Simulator. You may run it and debug small programs (.BIN or .HEX files)
Even though this is DEMO ONLY version, it is full feature Simulator with only one limitation : It will not load programs more than 2 KBytes in size. However this limitation applies to this free demo version only; the actual Simulator (which you can purchase) does not have any such limit for the size of input file.
