where are you located ?
there are still a few places to get film,
i've never processed it myself, but there are kits to that as well ..
i always sent mine out ...
this site is gone now, but the way back machine has an archive of it
it has some useful stuff ...
prep film in michigan ( usa ) sells double run 8mm
( if that bolex is like mine you run it through the camera,
take the spool out and run it through a second time )
john schwind's site might also be help
have fun !
(i'm looking for a sept, so i can shoot all the 100' spools of 35mm i have in storage )
