(I have a 1542A and was wondering if it was possible to upgrade >it to a 1542B with a ROM or something easy like that.) The 1542A and 1542B are very different adapters. As far as software goes, they are the same, but the physical differences are enormous. The 1542B is 8 inches long rather than the full length 1542A. The ROM's are not interchangeable. >Does anyone have a tech manual for them that I could get a copy of? Send me your address and I will get a copy out to you.
