The HP-15C Collectors Edition apparently has 3 firmware variations in it
and a magic key sequence lets you choose one at start up.  One choice is
HP-16C, though you need the correct keyboard overlay, sold by
https://www.thecalculatorstore.com/ .  I bought the calc and overlay for
the fun of it.  I also have a SwissMicros DM42 and played with using the
additional screen real estate that the HP-42S didn't have:

days. :-)
