Generic OS-9 editions
When sold to customers running GIMIX, SWTPC or similar minicomputers with attached terminals, the software was able to be configured for about 30 different models of terminals using the styfix tool. It was possible to recover most of the generic edition of stylo by patching the Dragon 64 edition with code from the FLEX-based stylo. You can find the application in the above list. Unfortunately it has not been possible to recover or reconstruct styfix. But all it did was to change the byte in address $000D of the stylo program to a different terminal number.
If you want to use Stylo for another terminal than VT100, then this is the list of supported terminals:

Dragon 64 edition
Stylograph was sold for the Dragon 64 through Dragon Data Ltd. It would only work in GO51 mode - a display driver that provide 24 lines and 51 columns of text. Since GO51 has unusual dimensions, a special terminal driver was created and spliced into a normal stylo executable in binary form. Additionally, the menu texts were shortened to fit. A new styfix tool was then written to prevent the customer from changing the terminal.
