History

Origins (1979-1986)

Gene Mosher began writing Point of Sale code on an Apple ][ in 1979. ViewTouch© as we know it today was first created by restaurateur Gene Mosher and C programmer Nick Colley in 1986, making it the ORIGINAL Graphical Touchscreen Restaurant Point of Sale Interface.

First Public Demonstration: ComDex, Las Vegas, November 1986
See historical photo

Early Platform: Atari ST computers (1986-1993/4 under Jack Tramiel)

Initial Funding & Support:

• Ed Ramsay (1986 - code development funding)
• Barbara Mosher (1986 - present, ongoing financial support)
• John King, M.D., Chicago (early funding)

Modern Era (1995-1998)

The current version of ViewTouch was created by Gene Mosher and C programmer Richard Bradley, transitioning to:

• UNIX (AIX) on Motorola PowerPC (1995)
• MIT's X Window System for network-transparent graphical interface (1995)
• Linux on Intel x86 (1997)

Major Funding: Billy Foster (1995-1998)

Enhancement Period (2000-2004)

• C to C++ transition (2000-present day)
• Extensive code enhancement by Bruce King (2000-2004) Ariel Brambila Pelayo (2025)
• Major Funding: Doug DeLeeuw

Gene Mosher's passion and vision has overseen the development, management, and maintenance of ViewTouch code across six decades, spanning a wide array of computers and point of sale equipment. Gene owns the ViewTouch copyright and remains active in ViewTouch in 2025. A personal note to everyone from Gene: I am getting on in years and everyone has always wanted me to tell them what will happen to ViewTouch if/when something happens to me. In 2025 I can reassure that I will be participating in the development of ViewTouch until my last breath, which could easily be 2050 (I'll be 101 then), and with Ariel, who is about half a century younger than I am, being awarded co-ownership of the ViewTouch code and documentation at ViewTouch/GitHub, nothing bad can happen, is going to happen, to ViewTouch. I myself used to wonder about the future of ViewTouch, but I no longer do wonder about the future of ViewTouch. It's going to be alive, healthy, vibrant and dynamic for a long, long time. A new chapter has been opened for ViewTouch in 2025 and I could not be happier about it. Anyone can be a part of the future of ViewTouch - I welcome all who will join us.
