I have never seen an OS/2 based ATM at a command prompt.  It must have been 
a windoze based ATM.  And many ATMs still run OS/2.  It is only being 
replaced by windoze on new models since IBM refused to support the hardware 
any more.

Do a google on BSOD and ATM for lots of photos of windoze based ATMs.

Large IBM customers have contracted for their own OS/2 source code line 
support.  IBM refers smaller customers who just need to purchase new 
licenses or get support for new hardware to Serenity Systems for their OEM 
version of OS/2.
