Thank you for this. I think I may even have the installer for V7 on a G4 Mac mini somewhere, but I don't know if I have still have the mini or if I sold it long ago. I recall it didn't work well on Classic OS (OS X classic emulation). It worked well on OS9 though, but I no longer have the dongle for this....LONG gone!
The garage project ended up being done on a drawing board in the end...probably quicker anyhow!
