          AIR486EL/25/33/50 is the high performance EISA system board.
          This board has :
          . Intel 80486 CPU at 25mhz or 33mhz or 50mhz.
          . Socket for the Weitek 4167 coprocessor.
          . 8K four-way associative cache memory built in the CPU
          . 64K or 256K secondary fast speed direct map cache memory
          . Four (4) banks of DRAM SIM which support
            upto 64MB of onboard memory.
          . Either 256Kx9, 1Mx9, or 4Mx9 DRAM SIMMs
             can be installed in each bank in mix mode.
          . Two (2) AT-compatible serial ports.
          . One (1) AT-compatible parallel port. "

         ;. Support Burst-mode for memory and IO.
