Q11. What processor upgrades are available?
A.
The 486SX/33 model is upgradable with the Intel ODP (Over Drive
Processor) microprocessor, which incorporates the full DX capabilities.
The system board incorporates the ZIF (Zero Insertion Force) CPU socket.
This makes it very easy to replace the microprocessor chip by merely
raising the lever to remove the chip and lowering the lever to install the
chip. The 486SX/33 can be replaced by the DX2/50 or DX2/66 as the
system board supports both types of microprocessors.
Q12. What is 'performance scalability?" Why is it important?
A.
Performance scalability means that when the system is upgraded, Wingine
performance also increases, or "scales' to match the increased
performance resulting from the faster processor. Since video data is
processed at CPU speed directly into VRAM via the Wingine architecture,
the system's Wingine features speed up to match the new processor
speed.
