I've taken the liberty of copying your picture and ringing the little devils in red. Not surface mount, easy to remove with moderate skills.
They have a polarity and the + side is marked on the board.
If the de couplers go short, they will bring the board voltage down. Sometimes they pop their caps off, sometimes not and can just cause so much interference that the board refuses to start.
I can't remember what values they should be but I will find out, it's not critical anyway.
They are made of a foil wrapper in a paper, they degrade over time and eventually give up or pop.
This will be a custom card made just for Denford so will differ from mine but its age will mean single or dual layer so not a problem soldering in new ones.
There is a wealth or detail on the Baldor site re mint. You need to be logged in but registration is free.

Once logged in you can go to legacy products, eurostepper and eventually here:

Mint version numbers:

ESMint 3.28 V1.6H/S-JDS means
mint 3.28, version 1.6 revision H, stepper only, J is job number and in this case customer DS (DEnford Stepper???)
Mint 3.28 is a system that reads a drip feed from the host pc, everything is fed from the pc unlike mint 3 etc which has to save config files etc.
So the battery backup is largely redundant. Mine isn't there any more as it leaked, no need for it. I'ts a rechargable so it will have given up the ghost many years ago anyway. What I an saying is that it can't loose it's set up.
There is legacy software you can down load form the site to talk to it.
Also, have you updraded windows? There was a massive change from Win2k to XP wrt serial communications. Serial coms software pre XP won;t run on XP and above.
Hope not a red herring?
