Just picked up a Series 1 Bridgeport that has been sitting for 15 years. Getting it cleaned up and finding what needs attention.
It has a DRO from Dynamic research corp...a model 700. I did some web surfing but can't find much info on it.
The issue it has is only one axis numbers light up. the scond axis lights up a - sign and the decimal glows briefly as the power is removed(this happens on the working side also)
Power always seems to be on when plugged in. I checked the on off switch and even moved the wires to the opposite side of the switch and it works the same.
Minus signs light up when powered and one display lights up after hitting the clear button but the other axis remains with only a lit minus sign.
The numbers are are removable (plug in) and I have switched a couple to see if they were burned out but they work fine on the opposite axis.
I realize it is very old electronics but wondering if it is worth a fix.
If it can't be fixed are the scales workable with other displays?
