Would this be it for 35 cents?

The bussed resistors with an integrated capacitor is hard to find. I believe it is acceptable to use a resistor network without the cap in its place

Yes, but this resistor network has nine resistors instead of eight so you need to cut off pin ten before you install it and make sure it doesn't touch the solder pad of the board.

The RC networks are a tough one to replace -- nobody makes the right version as a standard product. Looked into getting a batch made. Would have cost several $thousand... That pretty much explains the $22 each for an exact replacement.

It is acceptable to use a resistor network here as the caps don't do much on this circuit. See here for more information:

A better choice than the Bourns 10-pin 4610X-101-472 network would be the 9-pin version 4609X-101-472
This way, you don't have to cut the tenth pin. See photo on pinwiki link:

I made them myself.

All Parts ( including the prototype boards are available at Digi Key)
I will post the part numbers later the day.

Any chance you could repost the images? That forum hides images from non-members.

Oh, sorry. Yes i will re-post the pictures here.

So, if you want to make them yourselves :
Prototye boards: http://www.digikey.de/short/3r2ppv
4k7 resitor network : http://www.digikey.de/short/3r2pzj
(1k resistor network ( in case you need the combination with 1k instaed of 4k7 ))
470pf capacitors : http://www.digikey.de/short/3r2pz0

Here is a linkt to the manufacturers website of the uni-sip boards
http://www.capitaladvanced.com/uni-sip.htm

here are some pictures :

you can build the boards in 2 versions : withe pin1 on the left or on the right side.
so , this save space if you have to seat 2 of these face to face.

i know, it does not look very professional, but it works
i discussed the production with ingo kramer ( tz clock replacement ) using smd components, but there was not a huge demand, so that was to expensive.

The easy solution is to just use the bussed resistor that Ed (G-P-E) linked to:

https://www.greatplainselectronics.com/proddetail.asp?prod=4609X-101-472

Ed's a smart guy and knows more about circuits and their design than probably 99% of the people around here. If he says the caps aren't needed, they aren't needed.

No, there is two versions that you can purchase a 10 pin and a 9 pin. If you find the 9 pin you don't cut anything you just install it with the dot of the pack lined up with dot on the board. And hole 10 on the board is not covered. If you purchase the 10 pin pack you cut off pin 10 and install with the dots lining up but now the pack covers the tenth hole on the board but can't touch the solder pad.

Yep.

We manufacture this part now. You can either use our Molex 0.200” pins or make your own wires so they mount like originals:
