Datron 4700 - questions

[Drirr]

Hi guys,

I'm owner of oldschool and "vintage" Datron 4700 calibrator.

Some questions for other owners:
Is there any way to get service manual?
I would like to make EPROM backup, but I do not want to loose my calibration data located in SRAM. Is there any way to remove processor board with battery without loosing calibration?
Should I worry about EPROM content? Does anybody have backup?

Thanks !

Do a search of Datron and you get the 4000 and 4708,  maybe the 4708 share some designs ??
