Oh I loved this. My Tandy 1000 TL (or was it TL/2 ? I forgot) was my baby. I was talking about Deskmate on Usenet in the 1990s , publicly mourning the loss of PC-Link and such. Some of the stuff I did is found on tvdog’s Tandy 1000 site. I made a master list of Deskmate programs back in 1993 which was as complete as I could make it then. Pre web and all. Also, I made an 8-bit wav to snd (or was it snd to wav?) converter called DMSOUND in Turbo Pascal that got a lot of use and even got picked up a few years later and upgraded by somebody else who couldn’t find me online. [his documentation says i disappeared].
