content: Hi!I won, at a price I could afford (two figures and no bid–wars for a change!) a Gould "Classic" 6100 200 MHz 4 Ch Oscilloscope, sold as seen, d.o.a. with no display!Anything useful in the way of documents and capture software available for these?What about firmware/drivers, etc? Would I be up the creek from unobtainable firmware if it turns out to be a corrupted firmware or a flash memory failure?(My employer once gave me a TDS7054 to repair as an official job, and I'd no end of aggro restoring it because I couldn't get the original recovery CD, the only one I could find was from a seller that refused to ship outside the U.S!!!)Are service manuals known to be in existence and is there any "unobtainium" I need to watch for in these units?Chris Williams

content: Hello,sorry for being a bit slow here. First of all, look here:https://www.mikrocontroller.net/topic/185152They have USER manuals here, also in English if I recall correctly. As for service manuals, so far none has cropped up. There is a company, called Helmboldt or something like that in Germany which claims to repair these things. But, knock on wood, I did not need their services so far.If you ever do find something, let me know.Tam

content: Hi @Chris56000##Not sure if this will be of interest to you I am about to put on Fleebay my Gould Classic 6100 - It sadly failed due to the backup battery decided to leak all over the board and in the 6 months it was in storage the damage was done!.The display and other parts are functioning. But it will be appearing as "Spares/repair".RegardsMat/

content: I might be able to help, a little late to the party but still better than nothing!I have a working 6100, bought cheap as hell (350 PLN, so about 90 USD) because the battery inside leaked, but fortunately, no traces were broken, so I fixed it by replacing the battery and resetting the oscilloscope. If you need any measurements of capacitors, resistors, I'm all yours. I could also read and send you the EPROM's content, but I don't yet have a machine for this.I also have a PDF manual in English for it.Also, it's worth noting that the built-in display is getting very dim in a short time. I have a VGA output card in my 6100, so I usually run it on an outside monitor. If your scope powers on, try shining a strong light into the display and see if anything is on the screenIf you are still here, let me know if you need any help. I'm not a pro, but I fixed a lot of stuff over the years.P.S. It's not the one from the post above, I'm from Poland not ftom England, and I havd had it for almost 4 years now.
