Don't know where grognards gets some of its unofficial errata, but here is some unofficial errata on a game you have listed. Don't know if it's useful or not. Hale Cullom, Houston Unofficial Errata for Pacifc Theater of Operations (TSR 1991) By Hale Cullom (Ruffin1861@aol.com) (Errata on US Capitol Ships). Pacific Theater of Operations has a few irritating errors in its portrayal of the US battle line. To most players, this will be a small issue, but to us devotees of the big behemoths, such trivial little issues are simply too monstrous to pass up a chance to comment on. 1). Missing Ships. US BB Colorado (Maryland class BB) (4-12-28/2-11-18) should become available in spring 1942 (at the time of Pearl Harbor, she was completing refit at Bremerton, Washington - returned to service 31 March 1942, all of her war service was in the Pacific). US BB Alabama (South Dakota class BB (5-13-39/2-12-25) should become available in summer 1943. (She was in the Pacific from August 1943 for remainder of war). 2). Ratings of prewar USN capital ships. The ratings of prewar US capital ships appear to be somewhat inaccurate. PTO rates New York and Texas as 4-12-28/2-11-18's - as good as larger, newer Maryland class BB's with 16 inch guns-better than the Pennsylvanias which had two more 14 inch a piece. Both New Yorks were considerably older and smaller than even the Pennsylvanias - which were themselves hardly spring chickens. Although my Texas pride is flattered to see the Lone Star State's vessel "upgunned" so to speak, I think this is inaccurate. For home use, I have re-rated the two New Yorks as 3-11-28/1-10-18's, (like the Nevadas and Pennsylvanias - although even this is possibly too much). Moreover, the two Tennessees and the three New Mexicos have somewhat suspect ratings as well. The New Mexicos are rated same as the Marylands (see above) - which is possibly justified - they had substantially the same hulls as the Marylands, but 12 14 inch guns - more like the weaker 3-11-28 Pennsylvanias - although the New Mexicos had 14inch/50 calibre, which yielded marginally more range, than the 14 inch 45 calibre models on the Nevadas and Pennsylvanias. I think the New Mexicos should probably be rated as the Tennessees (built just after the New Mexicos)-- (3-12-28/1-11-18).
