Lucky me, I need to use a chip with 0.07" pin spacing (instead of the standard 0.1" dip). Does anyone know where to get sockets for these things? I've never seen them, and the usual catalogs don't have them...

Well, the hitachi 64180 augmented z80 chip has closely spaced leads in a DIP package also. Clarence Wilkerson

It was an attempt by Hitachi originally, to provide high density packaging for through hole applications. jeff -- Jeffrey A.

It uses .07" pin spacing, with .4" row spacing (for 28-pin socket) to .75" row spacing (64 pins). I saw some in the latest Mouser Electronics catalog, with 24 to 64 pin sizes. Their number is 800-346-6873, and their part number is 151-7xx-STT (xx = pin count) Dick Wotiz dick@portal.com

Its TI's TSP53C30. Called a "slim dip" package, I think. Unfortunately, they don't offer it in a regular DIP package. Does that match your def. of "goofy"?!

Sounds like a lot of fun to work with! I always assumed those dense through hole parts used 0.05" spacing. But I never measured one.

> What kind of chip is this?...
0.07" pin spacing sounds a bit like a chip used in an Eastern Bloc
country. Eastern Bloc packaging for standard DIPS uses almost 1/10
inch (~0.254 mm) spacing. Well almost, they rounded off to 0.25 mm
even. Rather vexing if you want to find a socket for a Russian IC!
Looks just like a western part 'til you try to plug it in. Makes
for interesting April 1 activities.
