all right so apparently the jukebox in Shaun of the Dead is an NSM Festival ES 160. even after reading through the instruction booklet and skimming some technical service manual i have no fucking clue.

i guess it can play single records for one credit or albums for three credits (maybe you placed records in set locations? it's unclear)
it also had some feature to keep track of no. of plays, and a 'Hit Parade' option, maybe that selected the most popular records? these 70s instructions are written like i already understand the general concepts of a jukebox.
