Since nobody (including me, the developer) seems to
have the original
RALF-format source files for OS/8 ADVENT, you've got to be careful to
replicate the environment used to build the .SV file. Normally, the
ADVENT.SV assumes that the files are stored on SYS: ...
ADVENT uses overlays (most FORTRAN programs did) and, although it isn't
well documented, overlaid programs must be run from the SYS: device. It's
because the overlay code assumes that the device handler for the overlay
file is resident and it can't load it if it isn't. A device that's
co-resident with SYS: should also work.
There's some more information about running ADVENTure on the WinEight
simulator here:
