What you do there is buy a cheap, commonly available calculator from the same period - I have have found that the basic 'Texet 880' model has a pin-compatible display, a Nat Semi part exactly the same size and shape as the original MK14 display.

That's what I have used in my (still unfinished) Karen-O emulator - but I tested it on my original MK14 first. (Years ago, I installed a pin row connector on the MK14 PCB so that it was easy to disconnect the display and remote mount it if I felt the need, and that makes it easy to test other displays on it).

The display from an otherwise broken Sinclair /Thandar /RS PDM35 DMM or PFM200 frequency meter is also the same, although unfortunately the latter items themselves command fairly high prices now especially if they are Sinclair branded.
