I got to answer my own question today, it's the 3rd Thursday of the month and I had the day off so I swung by. I found a sign next to the door that reads: RAMS Country Store is currently closed due

Thank you Jared, I've sent a pm to arrange shipping details etc.. David

Not a dumb question, but changing the mobo in a Waverunner Xi is apparently somewhat of a challenge. It also needs to work with XP embedded. David

I don't know the circuit here, but you may want to look at the logic and PIN control circuits and circuit descriptions in more detail. Sometimes a couple extra dB attenuation or passing, depending on

that was supposed to be shifts and xors

This might be a dumb question, but why not get a different motherboard? <david.partridge@...> wrote:

That sounds like a plausible theory, all though, what you described as a crc is really a checksum. A crc is similar but much more stringent. It is a polynomial with a characteristic divisor. In

Bert, Jeff, and Albert, thank you for the response. Bert, I am planning on replacing the line caps. Seems to be the No.1 item to address during my research. Definitely not leaving that out! I have

I used coax but even so the environment back there is so electrically noisy that the THD measured via the backplane is significantly higher than when connected around the front with BNC

Can somebody come out with any reason for the CR3068 diode on VR 2nd Filter Select board (left bottom corner on the schematic on page 185 of 494A/AP Vol.2 Service Manual)? There are 5 filters there,

I have the following CPU's spare if any of these will be of use: 1x SL6F9 - M705 1x SL7EG - M725 1x SL7SA - M740 2x SL7EN - M745 1x SL7V3 - M765 1x SL7VB - M780 I'm sure I could send one or two

David, here is the chip data. Lots of info to be found using a search. I have several Dell desktops and HP laptops from that era but you need to state if it is a desktop board or a converted laptop.

Hi David I have 8 Pentium, 4 Pentium 3 and 2 Pentium 4. But none have a M in their markings like M765 or M780. Have a couple 1 gb 2700 and 1 3200, several 512mb of this speed. Have 5 AMD processors

Looking at what I think is going on, it's possible that the processor was in the middle of writing to NVRAM and corrupted the process.  (it's write, and then write a checksum to validate the data). 

FIXED! "DJI ZH3-3D Damping Rubber Set (Part 42)", less than $10 at ebay. This is four bags of four different isolators, for an RC helicopter camera mount, one of DJI’s “Zenmuse” series. The

Dennis, in the affected regions is no power, no internet, no water, no food. So it will take some time to reach the people. Peter ==============

Last winter we had a power outage where the power co would turn power on for 15 min ever hour or so. The scope was soft turned off by the front button. Since then I have been getting the error message

If you are in the region affected by the flooding in Germany, Brussels, or The Netherlands pleased contact me (dennis at ridesoft dot com) if there is anything I can do or TekScopes can do to
