TM404ABA (TM404A?) 40x4 Dot Matrix LCD Module

[stevetob67]

Hello,

I am looking for some help please, I have seen some messages regarding a HD### model of these 40x4 LCD modules but there is a difference with the number of pins on the opposing end as the 2x8 pin rows. I was hoping someone has seen these modules around, I have got my hands on three of these, for some reason a couple of eBay sellers are selling the HD### models for around $40 AUD or so but these TM404ABA1 (TM404) versions are heading up around the $200 AUD price point. I don't for a minute believe they are this expensive but I picked them up in a grab bag from someone clearing some of their  excess stock.
I am looking to find a library that might work with Arduino as well as a pin description if anyone is able to help please, and help would be greatly appreciated however small. Hopefully the pictures are viewable and helpful.

if you are still looking 2 years later, or for those that end up here from Google,

The library is call LiquidCrystal440. Finding it without the name is rather difficult. I was written by  Donald Weiman (floresta on some forums) back in 2009 or so. It basically was a mod of the standard LCD libray to account for the two 2x20 LCD.  He had a site with some good information on the HD44780 displays. It is in archive heaven now -https://web.archive.org/web/20161104194254/http://web.alfredstate.edu/weimandn

EDIT: just make sure of the 2 row connector. There are three version that I know of, two are sort of inverse of each other.
