Hello all! 

I found a SR3000 vintage printing calculator at goodwill for $3. I have scoured the internet for information and I can't find even one photo or thread about this exact calculator. Any and all information is welcome! I wish I could attach photos but gmail will not let me. 

SPECS:  
Model no: 329.5874
Serial: 023138

Hello,
I confirm no information found over Internet.
May be you could open the back cover and find some information about the chips manufacturer, chips date code, ... that could help to narrow the search.
This machine is probably a clone of a calculator from another brand.

It's pretty similar to this model, although there is no documentation for this either!

By the way, it looks working at least the display is on. So maybe there are issues in keyboard or printer?

These can be fixed without need for schematics.
