Important Notice!

Dear SDI Customers,

We regret to inform you that as of 9/26/2025, SDI USA has ceased all operations. Due to the lack of sufficient management structure and an aging workforce, we are no longer able to meet the high standard of support and service our customers deserve. As such, we have made the difficult decision to terminate our company's operation.

Licensed customers are authorized to continue using their licensed software products without further License or Maintenance and Technical Support fees. However, no Technical Support services will be available. The software products affected by this change include TN3270 Plus, SDI LPD, and any other software licensed by SDI USA in the past. There will be no future product updates, no new releases, and no new licenses. The products should continue to perform their intended function until changes to the operating environment make it incompatible with our products. Feel free to continue using the products for no cost until you decide to move to another supplier.

We intend to keep the sdisw.com website available, but unmonitored until 12/31/2026. We recommend that you download the installation files, user guides and sample files and keep them in a safe place for your future use before the web site closes down.

We have witnessed monumental changes in the computer software industry during the past fifty plus years and have enjoyed working with so many outstanding companies and wonderful people over those years. We wish you all a prosperous future.

SDI LPD Prices


These are "per order" prices, not cumulative prices. So if you need 500 copies, it is less costly to order all 500 at once, in advance, than to place 5 separate orders for 100 copies each time.

Use the price calculator below to complete the calculations for you.

Please refer to the License Agreement and the Maintenance and Technical Support Agreements for SDI's exclusive terms and conditions of use and sale.

A license is required for each device on which SDI LPD is installed or used.
