Same issue here. Marked them as not spam and all is fine now.

Chipquick is definitely very useful when the project calls for it. JK

There are 9 EPROMs in v9.7 firmware in 494AP that should be the same as you have. They are part numbers 160-8315-00 to 160-8323-00. First 2 are on that memory board, rest is on GPIB board. I have all

Uh, aren't we on groups.io now rather than yahoo?? Yahoo is out of the picture. Sent from my Verizon, Samsung Galaxy smartphone

I thought our group was using "groups.io" not Yahoo.? Yahoo should not be involved unless they are your email client.? I use Yahoo email client and web based email.? That Yahoo client dumped all of

If anyone is having trouble with replacing components, maybe try Chipquick low temperature alloy. Recently I came into an obscene hoard of that stuff, and found that it works rather well. I don't

Right. various yahoo.com servers may have been downgraded in their trustworthiness and then the settings of your junk sensing flag it as junk. If you change settings to allow from yahoo it will

Grayhill makes some DIP switches that are sealed with epoxy on each pin, and I've seen them with a clear layer of tape that is to be removed after a board is cleaned. They are the types with recessed

Yep, have to agree with this opinion, wonder why? <grin>

All email is directed by your email program, not yahoo. It's possible that the classification of the yahoo email has changed somehow, causing your email program to put it elsewhere. You might want to

I am no expert on driving power FETs, however I think the biggest concern is the gate charge rather than Gate/Source capacitance ? There is a good deal of correlation between the two of course, but

Same here. Any ideas? www.cwgsy.net/private/mandoline "Error 008472. Horrible bug encountered. $Deity knows what happened."

Help, Now all my TekScopes email is sent to spam folder. Is this a Yahoo problem? Carl Hallberg (W9CJH)

This is interesting! I have a 3L5 with serial number J22. Would that also be a prototype? Bob Krassa AC?JL

Thanks for the documents. It indeed seems a good subject for tinkering and having fun building samplers. wrote:

Want to buy 495P v9.7 EPROMs which are installed on the A54 memory board. P/Ns 160-8316-00 and 160-8315-00. Or, complete working A54 board with these EPROMs installed. RIck K8EZB

When you want to align and solder a new SOC IC, I apply a little solder to one corner pin, then position the new IC on the pads. Then I heat the pin over the pad with the solder. If it looks good, IO

Pretty clear you're not helpless! For what it's worth, I find pulling a SOIC is simple with basic tools, I use solder wick along all the pins first then 'ping' each pin in turn by using a scalpel

The SO style makes it both easier and more complicated. I use a metcal iron with a very specific desoldering tip for SO width packages. If you're not familiar with metcal, it's a very nice temperature

Sergey, Thanks for your input on the Norway extenders. This is exactly the reason I am looking for someone who has been there and done that to repair my A54 memory board. Inside knowledge/experience
