Hi Chuck,


Maybe you can answer a related question to the conversion of IBM 360 .tap files.


I see the IBM FORTRAN Scientific Subroutine Package on Bitsavers in .tap format:


http://bitsavers.trailing-edge.com/bits/IBM/360/360A_CM-03X_Scientific_Subr_Pkg.zip


How do I read/convert this back into the ASCII files?


Thanks,


Randy

Subject: SIMH .tap file 7 track?

This is one that I haven't seen addressed.

If I'm reading a 7-track tape and writing a SIMH .tap file, what's the
custom?  6 bits per 8-bit byte, right-justified (i.e. 2 high bits
zero-filled)?

Just wondering if there's a convention established for this.
