We made a start on the temple. T1 was great but the PCs got a little bored by level 2 in the dungeon. They do not mind dungeon hacks but big hacks get a bit repetitive.
Your basic idea with ACs is correct and you can modify them if needed depending on how familiar with A&D armor you are. No offence to Alex but he may have made a small boo boo with attack throws as it is slightly harder to convert from AD&D or 3rd ed. AD&D-3rd ed conversion is a bit easier IMHO. I have played enough ACKs/AD&D/3rd ed I can convert in my head off the page as the DM.
ACKs and 1st ed both use the 1 gp= 1xp rule IIRC.Or at least BECMI did so I claim memory fart. ToEE is loaded down with gold though so in effect this means rapid xp gains. We also started with level 2 ACKs characters as they are kinda weaker in some ways than AD&D characters, a bit more powerful in other ways (the healing prof is very very good in ACKs).
