Hi to all usual suspects here.
You will maybe remember you helped me resurect my 7704A from decades of non working neglect. Thanks!
Here is for me a new challenge. I did a large leap in time from the 7704A and just bought a TDS520.
At boot:
All ok except:
FAIL++Acquisition
FAIL++ Attn/Acq interface
As soon as I knew it will be coming I read here all I could about it so I know that Artek has the documents.
Btw I want to praise Artek a bit here. I bought them the service manual for my two HP8640B I just bought too (yes, two is gluttony, I know but they were cheap and defective of course, so how to resist?)
Anyway Artek gives a really good service. The manuals are of upmost quality. I got them instantly and the charge is very reasonable.
I posted the boot to "TDS520 in Brittany"
/g/TekScopes/album?id=291619Also the 1993 rom: A11U1331 ver 1.5
There's a 7 segments inside at the back which only blinks alternately his two right segments.
Apart for the fails the scope is in perfect shape and was only very dusty inside. I disinserted all flat cables I could find and re-inserted them. I also removed the dust with hope this will change the fail boot (not really!) It did not.
All advices will be received gratefully.
