Unfortunately the DOS program it was being used to remote was highly picky on the hardware being used, and would refuse to communicate with the PLC if the PC was too new. Due to the harsh environment of the plant, we'd go through two or three computers per year. So there was a lot of digging around for old hardware until we realised it would run reliably in DOSBox with a suitable CPU speed set.
After that, our use case for TINY was no more, and we just used a VNC server for Windows. Saved a great deal of site to site travel and plant downtime while it was set up though.
