[sdiy] FS weird chips... collectors ???

[John Loffink]

Those are resistor DIPs.  Should be 470 ohm and 220 ohm.  The -3- signifies
the connection type, usually either all series or with one pin common to all
resistors and the other pins to the other resistor ends.  I don't remember
which one the -3- was but you can easily ohm this out with a multimeter.

I have some old Beckman chips, too. I've never found any info on them so...
any ideas ?

 

I have Beckman 898-3-R470 and 898-3-R220. Both are 16 pin white chips.
