[rescue] Sun ECL cables. Where ?

[SP]

Hello. I'm planning to purchase one Extron device to connect my Sun3 machines
to one VGA monitor. For this purpose I should need one Sun3 ECL cable, or
precise instructions to construct one. In the other hand, the Extron devices
use to have one 5-bnc output (at least as I could see in some of them) and
I suppose I should need one 5-bnc to vga converter. Same case than the ECL
cable.

I should agree to know about opinions and experiences related with this
matter,
and/or provision of cables and materials related with this.

About the Sunsolve and Manuals, contact me, Chris. All my messages to you
are bounced.

Greetings
Sergio
