If memory serves, the Cromemco Cyclops camera used an uncovered DRAM for the optical sensor. If so, that would be the most interesting construction feature of this facsimile version.
Yes. Dr. Garland and Dr. Walker have told me that they "decapitated" them both mechanically (with a very sharp chisel) and with heat (using a precise lab bench heat plate). I'm trying to decide which way to go myself. I only have a few to "screw up". I have a fairly high quality Pace SensaTemp soldering iron that can reach the required temperature (291 degrees C, I'm told). I have a large "mini-wave" tip that will hold a large drop of solder. I'm probably going to try that first. Lightly grip the chip in a small bench vice, mostly inverted. Bring the soldering tip up from underneath and apply heat until the cap shows motion, quickly remove the heat and push the lid off with a piece of wire. Bill
