The parts that you will need:

- a video capture device. I don't know about VGA input, but I do
  know that HDMI video capture devices can be had for prices
  ranging from $25 to $250 or so.

- transformation from video to still images can be done via the
  package imagemagick

- OCR can be done with the package tesseract-ocr


In future, if you can arrange to buy used server hardware
instead of desktop-class machines, you'll have access to various
IPMI (DRAC, ILO) serial console systems which include BIOS
access.
