- jacquesm 8d agoA lot earlier than that. https://www.cs.uaf.edu/2007/fall/cs441/support/dram_sensor_1984_whitehead.pdf https://www.cs.uaf.edu/2007/fall/cs441/support/dram_sensor_1...
- buescher 8d agoEven earlier than that. The cromemco camera and similar hobbyist projects dated from the mid-70s.
- jacquesm 7d agoI'm trying to date when we were first playing with this, but that was a messy period in my life and it is hard to put it all in chronological order. But I do know I had a driving license so it must have been around 87 or 88. The thing that I remember most clearly is that the images we made had a massive blank area where the chip was split into two halves with a bunch of stuff in the middle.
- xattt 7d agoI’m curious whether this is truly the first, or whether classified aerospace projects had quietly developed digital imaging devices for reco a decade earlier.
- buescher 6d agoI would guess that it's maybe not, because I've never heard of any IC DRAM before the commercially available Intel DRAM. Other types of imaging devices, sure. But the trick of decapping a DRAM requires a DRAM chip.
