The current (2009) is much more stable as it uses the USR to open the files, allowing you to move them around without causing ADVENT to crash (the save image has the disk locations for the files being used, meaning it'll crash if they move around.) https://www.rickmurphy.net/advent/advbin.rx has a floppy image with 2.4 binaries. -Rick

Pdp 8i with 32K. The issue was that I was missing two files Here is what works (from Dave Gesswein's site:), I was missing the 3rd and 4th lines: .R FRTS *ADVENT *ADVENT.TX/1 *ADVENT.DA/2 *$ .SAVE SYS ADVENT !Save the game .R ADVENT !And play. After the above one can just run the SV file to run Adventure: .R ADVENT.SV Also...if ADVENT is not in the boot partition you have to specify, i.e. .R RKB0:ADVENT.SV Bill

I’m just going to guess (I have no experience with this architecture) – would that mean either file corruption – or possibly the last record needs to be padded out with “empty” blocks to be the same size as the others?

That stands for Data File too big. "Product fo number of record times number of blocks per record exceeds number of blocks in file." So I have no idea how to fix that.

That's as opposed to "instruction field", which if too big would mean that there's too much code. Although I used OS/8 Fortran in the distant past, I never tried to compile large Fortran programs or programs that used much data, so I don't know what it takes to solve that problem. Maybe there is some way to get Fortran to use more than one 4KW field for data, issuing the necessary CDF instructions to switch data fields?
