OT: Obsolete device: LH0042CH

[Ge_Whiz]

I have just acquired three Signetics LH0042CH devices in eight-pin round TO-style housings. I'm guessing they are early op-amps. Might anybody out there have any data, esp. pin-out? I've searched the mighty Internet with no luck.

Thanks.

Here's the Google cache of the Signetics datasheet minus pictures.
cache of LH0042 datasheet

Luckily that part was also sources by National Semi who still has the datasheet online.

It looks like a nice TL071 and those 8 pin TO-99 cans sure have visual mojo value.

Take care,
