Yes it is possible, you can upgrade to a JCM/UBA, or the newer ivision series, or MEI (Mars). most are direct replacements, have to replace the shelf assembly along with the transport unit.
The most critical variable is each unit has to be programmed for the type machine. e.g. IGT machines have to be programmed for ID024,protocol , I think the Williams are ID003.
which ever you purchase make sure of the above software. and another element is the bezel. (duck bill)
MEI usually run 80.00 shipped, UBA are around 150.00 shipped, ivision are usually 275 and up.
