|HP-85 start-up error|
Message #1 Posted by John on 9 July 2003, 6:56 p.m.
On my HP-85 (A), when I have more than one interface module connected (all with different ids) I get the following error on power-up or reset:
Error 111 : IOP
This is with a full set of ROMs plugged in too. I can run programs and the modules all work, any clues what this error means please?
With only one I/O module the machine starts fine. I also don't get this with the same three modules on my 85B.

"An invalid input/output operation was performed. Use the ERRSC function to determine which interface generated the error."
