Hi Dave,
Thanks for Bob Armstrong's old email.
I have not seen Jim's VHDL code, but I am quite confident I can fix this.
Tom Urban wrote that the IOB6120 is misbehaving, so I will have to do some
fault finding or debugging anyway.
I would appreciate a short Fortran code snippet which reproduces the
problem.
I don't really want to have to learn how to play Adventure to reproduce
this. Games are not my thing except maybe chess.
That's pretty simple. A "Hello world" program will probably show it.
??????? INTEGER INPUT(20)
??????? WRITE(4,1)
1?????? FORMAT(1X,'ENTER A STRING')
??????? READ(4,2)INPUT
2?????? FORMAT(20A1)
??????? WRITE(4,3)INPUT
3?????? FORMAT(1X, 'YOU SAID ', 20A1)
??????? STOP
??????? END
Create "TEST.FT" with that content, then "EXEC TEST.FT" at the OS/8
dot
prompt.
If you can successfully enter a string and get a result, then you're
probably not having interrupt issues.
