ATTiny85 Invalid signature - ATTiny85-20PU vs. ATTiny85v-10SH

I've been successfully programming some ATTiny85-20PU with a self built programmer and Arduino Nano. These are the DIP package version.

I recently changed my design on my target board to use a surface mount equivalent, the ATTiny85v-10SH and now I'm getting invalid signature and programming fails.

Did I miss something? Is the surface mount version somehow different?

I'm using the internal oscillator/ 1Mhz.

My programmer has a ZIF socket which I dropped the DIP version into. I took a DIP socket and soldered a mini molex connector that goes to a female molex programming header on my target board. I've checked continuity pin for pin from the socket to the surface mount chip, its fine.

Here's the output:

Arduino: 1.8.7 (Windows 7), Board: "ATtiny25/45/85, ATtiny85, Internal 1 MHz"

avrdude done.  Thank you.

Currently my target board is empty except for the Tiny85, ICSP header, and power. I just wanted to populate it minimally to verify it would program.

|492x500

On the off chance that the chip was damaged I replaced it, still having the same problem.

Not that its important, but in the picture above the ATtiny is to the right of the connector, the wires are blocking the view.

I'm pretty sure I've figured it out, but I can't verify because I'm suffering the usual cluster f**k of problems where you figure out one thing and something else goes wrong. Somehow I seemed to have fried the Nano....

The problem was that in the picture you see the DIP socket adapter in the right side of the ZIF socket, I forgot it needed to be in the left side for programming..... grrrrr

Thanks to everyone for trying to help me figure out my stupid mistake. Now I need to order a new Nano....
