This confirms two things: 1) your A2 board is receiving the _RESET signal correctly 2) _RESET is de-asserted prematurely at power-on At this point, I would deal with 2) first, before even looking

The custom connectors were out of stock and going to stay that way because of moving to NM, but 30 of them turned up in the attic, (lost for a couple years). So now flex extenders are back, and: 1.

Interesting... The front panel lights extinguish when I press reset, and illuminate immediately upon releasing the button. The 'Busy' LED stays illuminated at all times. I just got the edge

Good Day to all: I have a 7633 that works well for the most part, however, it has one nagging issue. The "ALT" button does not display a trace from one of the two plug ins. This is regardless of

That doesn't sound right. There should be about a 3 second delay between pressing the POWER button, and the front panel lamps lighting up. That's because the lamps are normally explicitly enabled by

One thing to note - All lights illuminate immediately. The manual seems to indicate that it takes a few seconds to indicate an error code, but even when I was getting the bad ROM light pattern, it

My 465B periodically skips triggering event while I'm watching a trace. It's kind of like it has the hiccups. Maybe I should've been a little more conservative with the alcohol when I cleaned

What got us into this line of debate was my stating that I have found that store brands of 70% rubbing alcohol contain a bitterant. A brand of IPA, claiming to be USP, could not contain a bitterant

I don't shop at Walmart. Far too much of what they sell isn't made in the USA. The stores I have bought ISA from in my area have 70%, 91%, and 99%, but none mark them USP. That includes Costco,

To prolong this a little more, in the UK ethanol used in research _is_ taxed. I have seen bottles of ethanol with "duty paid" on the label when I was working - but I should add that it was "absolute

Please, people..... You all do realise that the Tektronix scope was already fixed over 20 messages ago!!??

Wow this thread has gone south. I didn't use alcohol of any sort. I used clean benzine. No water, no residue, strong cleaning properties and protects from corrosion...

Just IPA alone, has a slightly bitter taste... like a bitter fruit. (I've pipetted that too far, a few times.) I have tasted ethyl alcohol denatured with denatonium benzoate... a.k.a. as Bitrex, et.

CVS in Los Angeles has both 70% and 91%. Sold for medical use. Does not say USP on the label. I am not sure why USP registration is important for a cleaning agent. Note that the USP is a private

Now there must be news groups out there where people discuss the distilling of various kinds of alcohol ... so do the contributors also get slighty off topic occasionally and discuss the intricacies

Sunmark Isopropyl Rubbing Alcohol, 70% USP, 16 Fl. Oz., at Walmart. Cheers all. Roy

I need the two knobs that adjust the sweep speed on a Tek SC502 scope. I have several part numbers for these knobs but the descriptions shown on-line don't seem to match the damaged knobs actually

Well, they just want to get their cut of drinking alcohol. Industrial or medical ethyl alcohol is not taxed, only that sold for drinking is. So, its really the drinking that is taxed. The Volstead

Not that I ever would, but moonshiners are known for shoot'n first, and asking questions later... I suppose that maybe he meant "de-denaturing" denatured alcohol, then everything he said would be

We have just added lots of interesting Tek items to the Stuff Day page here: https://www.sphere.bc.ca/test/stuffday.html hopefully they will make all the Tektronix fans happy, plus I am adding new
