I found a copy of TP3 on the Adam Archive which sort of works, in that it will hang if one tries to edit a file using the TP3 integrated editor, but will however compile an external source file, such as one created with ADAMED. It's become clear that TP3 is not working well with the ADAM CP/M for some reason or other. It bugs me that I can't figure it out, but I guess I can live with that
Nonetheless, for my purposes at least, as long as it can compile a source file, then it will serve its intended purposes, particularly since I did not intend on using the TP3 editor anyway.
Here's a copy of the disk.
