Re: 7B53A seamless modification... Adding Alternate Delayed time base visualization (with trace separation)

Fabio Trevisan


Ah Hah! I knew it was too obvious for not having been thought of before!
On the other side...I`m kind of sad now. I was hoping that I had an original idea :-(.

At least, to save my face, for what I understood, they crippled the X1-X10 button to enable the Alternate mode...So I think my idea is better in that respect.

It's possible that I can implement my idea with basically the same circuit, just adapting it to use the "Var" control (and its detent switch) and thus, avoiding to cripple the X1-X10 functionality.

Thanks for the heads up.


P.S. Any chance to obtain a better scan of this microfiche?

That would be the same as or similar to 7B53A mod 178H.

but I have to warn you, it is extremely poor quality due to a poor original print and
microfiche original but with a little good will and fantasy most of it could be read.
