Re: Update on my 7854 diagnostics project
Hi Ke-Fong-Lin,
I think Holger's solution of having them done by a PCB house was quite clever and it is inexpensive as well.
There are a lot of franchise stores that make inexpensive signs. A simple

Re: Tek power cables, older equipment
Hi Sean,
David Holland beat me to the punch. The air conditioner extension cords sold by Lowes are a perfect solution once you shave off the little nubbin on the female end next to where the D-shaped

BTW I don't have a 475 myself and I sold my 465 long ago. For

Re: 475 questions
Hi Albert,
Are "low-homic" current sensing resistors different from any other resistor of the same rating?
I checked my vast supply of components and found four 47K ohm resistors. By the way, that

Thanks for the suggestions everyone! I think either the air conditioner cord or one of the adapters will be perfect for what I want.

For instruments like the 114 pulse generator, 184 time mark generator, and more. Does anyone know of a good place to either get these power cables? I have one, that came with my Type 114. With a 184

Jeff,
Excellent Project! I do not have one of these little scopes, but if I did, I would be buying this kit!

Thank you Roger and Albert for the excellent advice.
I have the rackable 7603 and side-probing on the live system is not possible. But if the middle bay is left empty then signals can be brought

Re: 475 questions
Hi Bruce,
Strange indeed that you measure 0 ohms at some LV lines while they come up to several volts when the 'scope is powered up. Is there any chance that something is wrong with your analog

The trick is: In this case the front panel is also a pcb ;-)
This board is 0.8mm thick, white soldermask and black silk screen.

Hi Holger,
If that's not a secret, where did you have your keyboard overlay card manufactured?
There's multiple sources of PCB fabs that are very good quality, and cheap.
