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.

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 ?

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. |
