HP-86A with 82937A HP-IB Interface
I have a HP-86A and would like to connect an external FDD HP-IB unit like the 9121 via 82937A HP-IB Interface.
With the card plugged in, when I turn on the PC, I get an error message like "I/O address error".
The 82937A HP-IB Interface is set to default address.
Could be that the reason?
Thx.

The default select code for the 82937A is '7' and on a 86A this will conflict with the integrated disk/printer interface.
