So, when I went to make a schematic of a board a while back, there was a resistor pack on the board marked:

1898-893-0
BECKMAN
7733

I have not been able to determine what type of bussed arrangement this part has, nor can I determine what the nominal value should be.

I get ~30K between any two pins I've tried, so have not been able to pin down which pins(s) are common.

Any one have access to an old Beckman catalog to look this up? I don't have much hope of solving this riddle, given the part dates from '77.

 

What package is the resistor network in?

 

D'oh! I hate forgetting important details. :-/

16-pin DIP.

 

There are only 2 configurations that I'm aware of. Bused with the power connection on the highest pin number and isolated resistors that are arranged flow-through (e.g. pin 1-16, 2-15, etc).

EDIT:

I hate forgetting important details. :-/

16-pin DIP.

My bad. You did mention it. I just forgot it by the time I had read the post...
