I've been downloading Commodore based magazines from Usenet on alt.binaries.emulators.cbm. They have been very nicely scanned into PDFs.
The list is pretty amazing. I believe Transactor has been posted as well.
You might want to take a look.
I converted the PDFs I wanted to JPGs and put them on my iPod Touch. I can browse through Compute!, Compute's Gazette, and .Info now when I'm waiting somewhere.
Good Luck!
