I am looking into the feasibility of a 42LC using the M5Stack Cardputer, which would be a longer term project, but considering there's already a Free42, Plus42 and DM42, I'm not sure how popular it would be.

For the K005 it is actually mentioned "Obsolete, This product is no longer manufactured" at Digikey. It’s regrettable!
It was the correct format for a calculator.

For the 42LC I don't know if the interest is based on competition from products such as DM42 but...
a 42S for the price of the M5Stack Cardputer is attractive! especially if the exchange of RAW files can be done with a PC. (see the post "dm42decode - a command-line decoder tool")
Fan of clones, I have almost all the DMs (DM11L, DM15L, DM41L, DM32, DM42, DM41X) but I also have the PXs (PX11C, PX12C, PX15C, PX16C, PX41C and the PX41CX prototype that I am testing for Alex Garza ) and what interests me the most is being able to transfer programs from one machine to another via PC.
So a 42LC why not! about $30!
