It's not too hard, I added GE's (GE we bring good things to life? LOL sorry I don't know why I thought of that) research mod over the TDM modpack and modded most of the TDM AI's to use it. If you're using the standard techs just copy GE's techarea file over your old one. If you're using a modified tech file just copy the two filler techs and add them in. Other than that you need to add in these lines to the AI research files

AI State := Exploration, Infrastructure, Prepare for Attack, Attack, Secure Holdings After Attack, Incursion, Prepare for Defense, Defend (Short Term), Defend (Long Term)
Tech Area Name := Filler Tech 1
Tech Area Level := 50
Tech Area Min Percent := 100

AI State := Exploration, Infrastructure, Prepare for Attack, Attack, Secure Holdings After Attack, Incursion, Prepare for Defense, Defend (Short Term), Defend (Long Term)
Tech Area Name := Filler Tech 2
Tech Area Level := 50
Tech Area Min Percent := 100

Personally I added them in as the 5th and 6th entries, because I use the starting resource setting of 100k that way the AI doesn't lose a lot of points. If you use a lower setting you'll probably want them as the third and fourth entries? Anyhow I'd suggest you download GE's mod and take a look at how he set up the AI files. That is if he doesn't mind us doing that?

PS GE did you ever play Traveller?
