Q4. What /eve/s of password security are provided with the Epson Endeavor
486C computer?
A.
The Endeavor 486C series of computers offer two levels of password
security to ensure 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 Endeavor 486C
series computer?
A.
The Epson Endeavor 4SX/25C comes standard with an Intel™ i486SX™
microprocessor (CPU) running at 25MHz. The Epson Endeavor 4DX/33C
comes standard with an Intel™ i486DX™ CPU running at 33MHz. The
Epson Endeavor 4DX2/50C 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/33 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 Endeavor 486C
computer?
A.
The Epson Endeavor 4SX/25C 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 Endeavor 4DX/33C 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.
