Big Wall Street banks, after spending massive amounts of money and time to get their old, creaking systems in better shape, are now trying to sell technology they've developed in-house to other companies. 

US banks including Goldman Sachs Group Inc, Morgan Stanley and JPMorgan Chase & Co are spinning out or selling a range of tools that pertain to data security, mobile applications and "systems integration," the process of flattening layers of aging technology.
