2 years ago Some sources of test listings and binary tape images:
- http://www.bitsavers.org/bits/DEC/ (PDP-8 and PDP-12)
- http://www.bitsavers.org/pdf/dec/pdp12/ (Some program manuals contain a copy of the full listing)
- https://so-much-stuff.com/pdp8/software/decus.php

At the moment, each test case consists of an assembly listing file and a "known good" machine code file. I think most of the machine code was either assembled by hand (suspect) or obtained online from paper tape archives (also suspect). It would be great to use the output of an existing PDP-8 cross-assembler as a comparison to validate our output.
As a preliminary goal, it would be great to ensure we have at least one test case for each permanent symbol.
