I wouldn't advise it as a method of 'preserving' the current contents, as it would be very likely to be blown during a battery replacement, but it's a reasonable way to continue to use the module. There's a classic reference on how to do this with SparcStation NVRAM modules, a conversion I do to almost every old Sparc box I restore. I'm not sure how to 'read out' the contents since I've never tried, but they're often the same SRAM/EPROM footprint. Anybody tried reading the contents with said EPROM programmer?
