RE: CBM SR-4148R Ship's Position Comparison
A very interesting article! The SR-4148R was my first scientific calculator and the dual memories and summation function really came in handy in this application. The article also mentions using early satellite navigation where it might take several hours for a satellite fix to be received. Thank you.
