Here are some .WUs for decus software, that I found
and that I didn't find on
   so-much-stuff.com/pdp8/software/decus

I scanned them with 300dpi and make the .pdf searchable.
(Don't know if that is of any use.)

The Decus Program Library Catalog has no date, the last
few pages are missing.
The highest program number that I found in the directory
is decus-8-206. 
The .WU for 8-204 has a date of 18-APR-1969. So I assume
this catolog is from late 1969.
Because the catalog is printed in a relative tiny font, I
scanned it twice: 
  with 400dpi for better readability
and 
  with 300dpi to allow searchable .pdf.



I also found a few papertapes:
  decus-5,8-18c.bn 
this is not on so-much-stuff.com/pdp8/software/decus.

  decus-8-162nwb.bn
is on so-much-stuff.com/pdp8/software/decus. But my version,
as well as that on so-mutch-stuff, both have checksum-errors
when trying to load them. Both versions have significant 
differences, maybe due uninitialized memory.
The first words of code starting at 0400 are identical.
Sadly I have no 338 graphic subsystem, so I can't figure out
if they would work even with checksum-errors
 
  decus-8-178.bn
is on so-much-stuff.com, I just copied it, because I loaded
it from papertape to test if checksum was correct.
