POS (Point of Sale) software for standalone C90LEW XPe?

Hello,
I'm new to Wyse thin clients and new to this forum as well. I was hoping to get some help with setting up 2 Wyse TC's with standalone POS software to run my 2 small shops. I don't need anything fancy, just POS to keep tracks of the transactions. I will have to reimage the 2 used C90LEW that I recently purchased and will need to find a POS software to install in them. Would you please suggest and/or give me some clues as to which POS software I should get? Nothing fancy, just some standalone POS software that I can install on these thin clients. Thanks very much in advance for your help.

Regards,
Joe
