i was just doing some work on my sds9 and i realised that i have os v6.0
this seems to be newer than anything else i can find online.
v4.0 was the newest i could find.
luckily i have an eprom burner, so i've made a copy to share with the world.
i wanted to upload it to the files section but i don't have an "upload" button anymore.
here is a link to my google drive:
