HP 71B factory reset Message #1 Posted by inaki on 14 Nov 2005, 7:42 a.m. Is there a way to factory reset the 71B ?

Re: HP 71B factory reset Message #2 Posted by Diego Diaz on 14 Nov 2005, 1:20 p.m., in response to message #1 by inaki Hi, Just press and hold [/] while pressing [ON] You'll see "INIT: 1" on the display Press [3] to change it into "INIT: 3" (full reset) and then [END LINE] to execute. You'll get "Memory Lost" Cheers. Diego.

Re: HP 71B factory reset Message #3 Posted by inaki on 14 Nov 2005, 7:45 p.m., in response to message #2 by Diego Diaz Following this sequence I cannot get the intended message 'memory lost'. The calculator locks when I press end-line, after changing INIT:1 to INIT:3. Thereafter I cannot return back to the starting point! The only thing I can do is entering the same INIT loop again! What happens here ?

Re: HP 71B factory reset Message #4 Posted by Garth Wilson on 14 Nov 2005, 8:02 p.m., in response to message #3 by inaki After non-BASIC programming mistakes, there was a time or two I had to remove the batteries, short the terminals together, and hold the ON button down for awhile to get it back on its feet again. I also had to do this after making the mistake of doing something like DIM D$[128](30) (with the maximum string length and the array size in the wrong order) in a text file and then TRANSFORMing to BASIC. There's a serious bug there that causes a crash that even INIT:3 won't always bring it back from.
