Good site, works ok and you get what you order, no problems experienced, got my manual within a day. A++++

Original well scanned manual. Got the job done. Microwave problem found & corrected. For $5 and a new magnitron from ebay, it was a cheap and good the first shot fix. Electrical schematics allowed me to mage sure every thing else was ok before cutting and order for parts. Hard to live without.

I was very skeptical of this website, I have never downloaded manuals before. I put it on the AMEX and payed through Paypal to ensure protection. I got the manual exactly as described and now I can replace the filter capacitor for this amp. Great Price, others selling for 12.99 or more and this is the same manual. I will search out this website for other manuals. Thank you

Manual was reasonably easy to follow. I am not an engineer or know much about electronics but with the manuals help I was able to figure out the problem, identify the part required for the repair. Replacement part cost around $30. Whilst replacing the part I was telling myself, "this aint gonna work cos it seems far too easy". Took about 15 minutes to do and my plasma TV works a treat. Would never have been able to do this without the service manual.
Motherboard Description
1.2 Processor
The motherboard supports a single Intel Pentium II processor. The processor�s VID pins automatically program the voltage regulator on the motherboard for the required processor voltage. In addition, the host bus speed (66 MHz and 100 MHz) is automatically selected.
CAUTION
The WS440BX motherboard supports Pentium II processors with a 100- or 66-MHz host bus. Processors with a 100-MHz host bus should be used only with 100-MHz SDRAM; the motherboard will not operate reliably if a processor with a 100-MHz host bus is paired with 66-MHz SDRAM. Processors with a 66-MHz host bus can be used with 66-MHz or 100-MHz SDRAM. The processor is packaged in a Single Edge Contact (S.E.C.) cartridge. The cartridge includes the processor core, second-level cache, thermal plate, and back cover. The processor connects to the motherboard through the 242-contact slot connector. When mounted in the 242-pin edge connector, the processor is secured by a retention mechanism attached to the motherboard. Processors with passive heatsinks are stabilized by a heatsink support that is attached to the motherboard. The motherboard supports the following processors:
Processor Type Pentium II processor Processor Speed (in MHz) 233 266 300 333 350 400 450 Host Bus Speed (in MHz) 66 66 66 66 100 100 100 Packaging Type S.E.C. cartridge
1.2.1
Second-Level Cache
The 512 KB second-level cache is located on the substrate of the S.E.C. cartridge. The cache includes pipelined burst static RAM (PBSRAM) and tag RAM. All supported onboard memory can be cached.
1.2.2
Processor Upgrades
The motherboard can be upgraded with a Pentium II processor that runs at a maximum speed of 450 MHz. When upgrading the processor, use the BIOS configure mode to change the processor speed (see Section 1.14).
