    Hi all,
    I have just gotten round to repairing an old Gould DSO 420.
    I have the scope workng now but and I would like to get the plotter workng as well. Does anyone know where to get replacement pens for the plotter?
    Also does anyone know how to upgrade the firmware for this scope?

    Regards

    Ian

    Hello,

    I have tried to get pens for my one, I found one place advertising them. I emailed them and never got any replies.
    I actually have a couple of 400's, a 450 and a 1604. I have the service manual as a pdf. If you need it, PM me your email address and I will send it to you. It is around 10Mb in size.

    Daniel.

    Just realised that I wrote "scoope" instead of scope. Oh well thats what alcohol does to the spell checker.
    Thanks for the offer but I have the service and operational manual.
    Who was the company that had the pens if you dont mind me asking?

    Hello.

    I am still here, but have been very busy with a very large project.

    Anyway, I do have the service manual for these scopes. PM me your email address, and I will forward it to you.

    Daniel.
