*The procedure for enabling the math coprocessor is different
depending on the version of the "MCY" system board. Also, since
this computer uses the NEC V30 microprocessor, Intel cannot
guarantee compatibility. Contact Epson for information.

Note: You can't use a memory board, such as an Intel Above Board, in
these system boards once the MCP is installed.

*This system is not compatible with i387 MCPs marked 80387SX,
80387SX 16-25, or 80387SL. The incompatibility is caused by a
particular stepping of the VLSI chipset used in these systems. The
use of an MCP marked 80387SX-16 or 80387SX-20 (a slower
speed-marked MCP) may inhibit the errors caused by this chipset.
If problems persist, users should contact Epson.
EQUITY II 386DX-33 Model Intel387 DX
This system is NOT compatible with Intel387 DX Math CoProcessor.
Epson recommends the use of the Intel387 DX-33 MCP instead. Epson
