ESA (Electronic Solutions Associates) has been selling 486 mainboards for commercial and industrial embedded applications for several years. We have found from experience that the commercial 486 motherboards that were available were not always suitable for our embedded customer's needs. Some of the problems we had were typical for the PC market, like rapid design changes and poor quality control. We decided to design, develop and manufacture our own 486 mainboard with all the changes and features we wished we always had (like 8 free and clear ISA slots).

Our 486 motherboard was designed to high quality standards with quality components. It is an "AT" format board with 8 unobstructed 16-bit ISA slots and one shared PCI slot. In addition, some of our current customers requested some features only offered on costly Industrial "Single Board Computers", i.e.: "watchdog timer" and "DiskOnChip".
We expect our 486 motherboard to have a long production life with no "rev" changes planned for the next 2-3 years. In the event that essential components are to be discontinued, ESA will provide our customers the opportunity for end of life buy.

For our customers that need more CPU power, we can offer some 586, PIII, or P4 motherboards with more than the usual number of ISA slots in ATX form factor.

Due to steady growth, ESA has moved to an office/warehouse in the Tampa Bay area. Our new offices will allow us to grow and provide better products and services.
