Another method of checking any data on any physical device
is to use the RT-11 program, DUMP.SAV, which will display
the individual blocks in the case of a disk drive and the individual
records in the case of a tape.
Unfortunately, my PDP-11 hardware is not available right now.
But I was able to use Ersatz-11 to perform the same operations.
Three 80 byte records and 4 tape marks are displayed as in:
First 80 byte record
Second 80 byte record
Third 80 byte record
If you can display the above data when you INIT the TK70
media on the PDP-11/83 under RT-11, but can't read a TK50
media produced under VMS, then perhaps there may be a hardware
Let us know what you are able to see. Then we can help some more.
