Thanks Christoph! There is nothing like getting details from the actual source!
I had not thought about household lights but my house is full of compact fluorescent bulbs (CFL). I will dig out an incandescent to light my little work space.
I have tried it yet some more: 2 separate 17Bii calcs, both the 48SX with 128 KB RAM card and the 48G with boosted RAM chip, varied spacing between the devices (5 - 15 mm?). I think I am up to 12 attempts now! :-) The closest I have gotten is slightly over half the image acquired accurately. This number comes from CAPC2BIN reporting correct blocks (~0x8100(??) is the highest I have achieved). When I compare the dumped partial result from CAPC2BIN to an actual dump (same ROM version), it certainly looks like I am loosing sync along the way. (I seemed to have acquired a copy of the ROM from a kind soul in the last little while that was not sourced from one of my 5 17Biis -- the 2 I am trying to dump, one which I busted, one which is out on permanent loan to my sister, and the last one is the international which is my ultimate target -- but it has a fair bit in the SOLVER area that I will have to copy down and reload.)
It was suggested that I make sure that "NO AC ADAPTER" is on in order to space out the stream (I think that was idea). I will try that as well.
Thankfully, my little triple AA hot-wire adaptor (a little balsa wood, 2 thumb tacks, some wire, and an external battery holder) has lots of juice! I do not intend to give up until I get that darn thing dumped. After all, it has been claimed to be "easy" by many folks. :-)
