Never thought I'd see not one but two! They are at a nonprofit I help out at. Nobody knew what they were except for me. I know it was for troubleshooting GM cars, but not sure what the purpose was. Looks to have a PC or XT inside along with a PCjr thermal printer in the cabinet! The computer seems to have several interface cards in it including a GPIB. I won't be able to save the entire thing, but will most likely get the computers out of them.
