Yes, you can do everything with paper tape. My first DEC system was a 
PDP-5 with paper tape only.
You read the editor into memory off paper tape, read your source off 
tape then punched a new version.
Then you loaded the assembler off paper tape, punched a bin paper tape, 
etc... very painful.

Under OS/8 it's a lot easier and more convenient. You can use the line 
editor or TECO. With a VT-52 emulating terminal, VTEDIT is a very 
friendly editor. (However, I'm TECO-biased. I created the VAX TECO 
editor for VMS.)

If your terminal emulator can't do VT-52, I do have a copy of OS/8 TECO 
and VTEDIT that works with ANSI terminals. Getting it onto your PDP-8 
should be pretty easy if you've got Kermit running. (I use PUTR to move 
things on and off my SIMH drives.)
