VCF weekend in the Midwest

^^^^ You mean 9831, I think. The 9830 is a very different machine (I have both, I also have full schematics of both). I haven't. but I am _certain_ the machines are otherwise identical (well, apart from the keycaps, there are half a dozen differnces in the key labelling, but the keuboards are electircally identical). Of course the later 9825s (-T and something else) have the 32K RAM/ROM board and maybe another 32K RAM board, and don't have the system ROM cartridge in the side. You can't turn those into a 9831. I've never sene a 9831 with the full keyboard. You can swap the chicklet and full keyboards (they are electrically the same), but as I mentioned there are some labelling differences. -tony
