All,
Try to be gentle as this is my first venture into video game realm and I think I am in over my head.
I am trying to figure out what someone did to a Gauntlet Legends arcade that I got at auction. This should use a medium resolution 27" monitor by the manuals I have found. I have not measured the monitor yet but I think it is still a 27" since there is not much gap to the side of the cabinet but the Vegas I/O board has the dip switches set to Standard Resolution. (SW1 OFF) The chassis has some masking tape on some of the metal heat sink (I say heat sink may be a something else) that says K7400, a date, and "good". The chassis board has stamped P763 in one corner. I have tried to match pictures of the K7400 and K7500 chassis pictures and they look too similar to me right now for me to tell.
Could someone have kept the tube and replaced the chassis to be a K7400? or would the tube have needed to be replaced also? Are there any markings that I can go by to identify what I have in here to start with? Like what resolution tube is in here and what chassis is installed.
Thanks for the help,
Marc Davis
