Q4.
What levels of password security are provided with the Epson Equity
4SX/25, 4DX/33 and 4DX2/50 computers?
A.
The Equity 4 series of computers offer two levels of password security to
insure that unauthorized users do not change the system's SETUP
configuration or obtain access to the system.
- Password security to obtain system access
- Password security to access SETUP menus
CPU
Q5.
What microprocessors are being offered with the Epson Equity 4 series
computers?
A.
The Epson Equity 4SX/25 comes standard with an Intel i486SX
microprocessor (CPU) running at 25MHz. The Epson 4DX/33 comes
standard with an Intel i486DX CPU running at 33MHz. The Epson Equity
4DX2/50 comes standard with an Intel DX2/50 CPU running at 50MHz.
Common features of the different microprocessors include backward
compatibility with the 8088, 8086, 80286, and 80386 CPUs and a built-in
8KB cache. For system flexibility, the built-in CPU cache can be disabled
via SETUP.
The i486DX and DX2/50 CPUs contains an on-chip numeric coprocessor
to increase the speed of floating point operations. This coprocessor is
backward compatible with the 387DX and 387SX math coprocessors and
complies to ANSI/IEEE standard 754-1985.
Q6.
What processor upgrades are available in the Epson Equity 4SX/25,
4DX,33 and 4DX2/50 computers?
A.
The Epson Equity 4SX/25 computer can be upgraded by installing an Intel
i487SX or Intel Overdrive CPU in the processor socket. Both of these
CPUs improve system performance by adding a numeric coprocessor to
speed up floating point calculations. The Intel Overdrive CPU doubles
the processor's internal speed to further increase system performance.
The Epson Equity 4DX/33 computer can be upgraded by installing an Intel
Overdrive CPU in the processor socket. Like the Intel Overdrive CPU for
the 4SX/25, the Intel Overdrive CPU for the 4DX/33 also doubles the
processor's internal speed to further increase system performance.
Please note that the Equity 4SX/25, 4DX/33 and 4DX2/50 computers do
not support the Weitek math co-processor.
