Lem,
Actually you are right regarding the anti-skid. On the "classic", the last amendment (dec 7 2001) the sentence, antiskid protection is available even with loss of both hydraulic systems, has been added to the Antiskid Protection chapter.
On the "NG" this has not been added. Where the chapter Antiskid Protection says that antiskid protection is provided in the normal and alternate brake systems (nothing is said about the accumulator brakes). I "guess" they forgot to amend this one. I will ask my fleetchief to check this with Boeing.
Anyway good that you challenged me to check both my FCOMs.
