Ok. It sounds as if a new ISS board will work with an old VP2 system. Next step. 4wd, et al, 40 to 50 years ago I would ask no further questions and just go for it, but older and wiser, I recognize my limitations. Would you please give me the removal and replacement steps for the board, paying particular attention to those you think an old f*rt might have trouble with. Oh, this is wireless so it looks to me as if I might need to unsolder the antenna (which could be problematic)?
TIA
