On Steve's SU4 copying saga, it sounds like Steve had the copy-protected, self-booting SU4, while Terry has a non-copy-protected one. Both existed.

I have the non-copy-protected version available for download on http://tim-mann.org/misosys.html#down, as a /cmd file that you would have to import onto a TRSDOS or LDOS 6 disk, say with an emulator utility. Once you import it, this is the easiest version of SU4 to deal with.

Once you import it, this is the easiest version of SU4 to deal with. I also have a copy of a preliminary version of the self-booting SU4 (from Kim Watt's personal collection). I've never seen the final released version. My notes say that I successfully copied this version to DMK (using a Catweasel and cw2dmk) and it worked in xtrs. My notes also say that it was not representable as JV3. So a copy-protected SU4 that works as a jv3 but can't be copied to dmk by jv2dmk sounds like a really odd duck. I would be interested in a copy of that jv3 to see what it is and why jv2dmk doesn't work on it -- would also like to know where it came from. --Tim
