Hallo David,

BINGO, thank you, David !!!
We knew from other sources that the Vpp = 25V. Your GIF confirmed my
yesterday's theory that the ChipSelect-line is used both as programpin and
as programvoltagesupply. About the algorithm: I would start with pulses from
10 ms up to 50 ms until the data is stored.
But I probably have one problem: is my prommer capable of supplying this pin
with 25V ?
