CPU
What are the microprocessors being offered for the Epson
Q5.
ExpressStation?
A.
The Epson ExpressStation supports all of the i486 CPU functionality. The
Epson ExpressStation will be offered with either a 25 MHZ i486sx
microprocessor or a 33 MHZ i486dx microprocessor. Common features of
the two different CPU's include backward compatibility with the 8086,
80286, and 80386 CPUS, burst mode bus cycles, and an on chip 8kb
cache. The cache can be disabled via either the software or hardware.
The i486DX CPU contains an on-chip numeric coprocessor to increase the
speed of floating point operations. This processor is backward compatible
with the 387DX and 387SX math coprocessors and complies to
ANSI/IEEE standard 754-1985.
What processor upgrade sockets are available in this computer?
Q6.
A.
If the customer bought the 486sx/25 mhz. version of the computer, the
Epson ExpressStation can be upgraded by installing an i487sx component
in the socket. This improves system performance by adding a numeric
coprocessor to speed floating point calculations. Please note the
ExpressStation does not support the Weitek math co-processor. There is
no upgrade path at the current time for i486DX based systems.
