This is interesting; the display can show the whole stack (my daily driver, a 35s has only 2 lines, and the 32SII only has one). Keyboard looks fairly similar to a 32SII in layout; no arrow-keys like the 35s.

Given that it takes only a single battery, I suppose it stores programs in non-volatile memory rather than SRAM (my 35s has two batteries and you need to change them one-at-a-time to not erase the memory).

Keyboard layout is identical to 32SII, save for the orange-shifted SETUP above the ON key and an extra top row of blank keys, presumably for some kind of menu functions. Interesting indeed. The 32SII's forte has always been pure number crunching, with most functions reachable with a couple of keypresses. It had a rather limited program memory, which this version can rectify.

Having a single battery shouldn't preclude SRAM storage; there could be a small capacitor capable of preserving the contents for several minutes.
