(OSKA0501 is a faithful Fortran->F77 port of ANON0501.)
(ODWY0551 is a faithful F77->C port of MCDO0551.)
(CALH0350 and DAIM0350 are C->C ports of POHL0350.)
(HALL0501 is an F77->C port of MCDO0551, by combining with POHL0350.)


WOOD0350   | 1 file, none, none, none, no spider

It seems clear that LONG0501* must have had:
  unknown number of files, <Adventure-- Version:5-something>, Dillinger on poster, unknown author, maybe spider 
and LONG0751* must have had:
  unknown number of files, <Adventure-- Version:6-something>, Dillinger on poster, W.I. Zerd, no spider 

Re the authorship of "History of Adventure": It's clear that MCDO0551 inherited "Ima Wimp" from
ANON0501. It's clear that LONG0751* used both "W. I. Zerd" and "W. I. Zerd, F.R.C.W.".
("F.R.C.W." might stand for "Fellow of the Royal College of Wizards", possibly indicating
British influence.)
It's unclear whether LONG0501* used "Ima Wimp" (and ANON0501 inherited it), or whether LONG0501*
used "W. I. Zerd" (and LONG0751* inherited it).
