I owned one of these computers when they first came out. We were all astonished and very excited about it there on Grand Cayman. Many of us had been owners of the Scubapro "Bend-O-Matic" and were eager to have something that worked.
The first time I took the Edge deep it cracked me up...the screen went blank and the letters "TILT" were displayed.
Now I dive my Shearwater Predator and think of the incredible leaps and bounds we have made in this technology.
Ah yes, narcosis
I do not remember coding a "TILT" display.
The message screen that came on if you went beyond the 160 fsw limit of the transducer was: DEPTH RANGE HAS BEEN EXCEEDED
We designed message screens on graph paper and then coded which pixels were to be turned on and which were to be switched off.
I had originally coded a skull and crossbones display, but that got vetoed...
