The complete source code of TP3 that I generated and of this tool is free, just ask me (see my website for the email address). So far I used the code to turn it into a tool that turns a given PAS file directly into a COM file. To make a long story short: there were errors in the original source code like hard coded pointers like "move dx,1234h" instead of "move dx,LABEL" and more of those funny things. The COM generated by NASM is not byte exact to the original TURBO.COM due to different codes for the same opcode instructions but it worked. WordStar was a word processor originally released in 1978 which was extremely popular in the early 1980s before losing ground to other word processors (particularly WordPerfect). It worked and the next step was to turn the generated MASM code in NASM. Quite some time ago I found a tool to turn the original COM of TP 3.01 into its source file including comment. I'll have a look at it anyway, you never know what interesting bits can be found. It only supports lines of 80 bytes and that is not what I have in mind.
