Y'all these days are spoiled with your headers, test clips, howto videos and cheap EPROM programmers.
Had to reflash an i2c 24-series eeprom on a satellite receiver. You don't want to power the whole board, so gotta lift the VCC pin off the SOIC chip (not hard if you warm it up and pick at it with a soldering iron), solder kynar to leads/nearby lines for VCC, data and clk lines, and aligator clip for GND. Connected to some self-made janky 24 series parallel port interface.
