If you think how a CCD basically works, it has a series of electrodes (normally 3 or 4 'phase' drive) on the surface of the chip, by sequencing the votlages on these electrodes, you move the accumulated charge along. Charge transfer actually occurs as the voltages are changing, which means the rise/fall time, and to a lesser extent the shape of the rising/falling edge matters. Too steep can be a problem. I spent many a late night looking at the 'scope and adding low-value series resistors to slow things down a bit. My minis have RK05s and the like. 2,5M on a pack is not a lot of use for this. OK, I have a couple of RK07s, but they're 'only' 28MBytes, and I don't have that many packs for them (enough to use, bot enough to use for archiving images). No, but I am told CD-ROMs are useful for sending said scanned manuals to places like Bitsacers. -tony
