I would like to get a new dro display for my mill.It has a sony magnascale on it I,m guessing about 20 years old.The connectors from the scales are rectangular boxes that fit over circut bourds inside the display.Will a new display fit with old scales?Does anybody make adaptors? The reason I"m asking is that I was going to buy a dro for my lathe and realized all the new dro have function like bolt hole circle ect. that I could use on my mill.So I thought I woud buy a new display for my mill and use the old dsplay for my lathe and buy used scales.The scales on the mill arent the right length for my lathe. I figure I cant be the first to encounter this problem.What should I do? Just trying to save some money.
