Update: the AMDM001 arrived from lcdperfect, and I can confirm it works correctly with version 2 of the OP-1 (the version with the smaller screen and higher circuit board that the screen connects to).

It appears there are three versions of the screen as of 2021-03-10; I cannot currently confirm if ver. 2 or ver. 3 are accurate, but will update in about a month when I receive a ver. 2 if they are not accurate:

ver. 1 : 74-x000045, can be currently found on eBay ; this version is the one is shown in the example

ver. 2 : AMDM001, will need to purchase from LCD-focused or bulk electronics sites such as enlcd; this one has a connector piece on the ribbon to snap onto the circuit board, and is smaller than 74-x000045; it is NOT interchangeable with ver. 1

ver. 3 : AMEJ006D, even worse scarcity than ver. 2, only found one listing on eBay, none from LCD-focused or bulk electronics sites; looks similar to ver. 2; it is also NOT interchangeable with ver. 1. However, it looks similar to ver. 2, so it MIGHT be interchangeable with ver. 2 — I haven’t been able to test.
