HSI has provided expert consulting and custom programming for the THEOS operating system environment since 1983. With a current supported installation base of over 50 sites, we stay up to date on all THEOS-related issues.

HSI has particular expertise in:

• C Programming
• TCP/IP networking
• Data conversions to/from THEOS systems

We also have a number of system tools created to help understand and document existing THEOS Basic programs and data files to aid in conversion to other systems or maintenance of existing applications.

HSI has created several interactive web sites using the THEOS operating system as a platform; we can interface with existing applications to extract and update data.

HSI can install and support your THEOS system, including upgrades to the Y2K compliant THEOS 4.1 and THEO+Net (Netserver).
