I'm trying to program 8 ATTiny85's I purchased from ebay but I can't seem to get any response from them.
I have tried following several guides and even tried to use High Voltage Serial Programming using this guide on one of the chips with no success.
I've set up my UNO as a programmer and using the debugging lights can see that part is working. But I keep getting the response "Device signature = 0xffffff" on all 8 chips.
The latest thing I have been trying to do to check that they are even working is burn bootloader with the following command
C:\WinAVR\bin> .\avrdude -v -p t85 -c stk500v1 -P COM13 -b 19200 -e -U efuse:w:0xff:m -U hfuse:w:0xdf:m -Ulfuse:w:0x62:m -F -B 5
and this response:

Would you like this fuse to be changed back? [y/n]
If I enter 'y' it gets stuck in a loop trying to change the hfuse.
Any help would be greatly appreciated.
EDIT:
Any time I have run the below command on the chips
C:\WinAVR\bin> .\avrdude -v -p t85 -c stk500v1 -P COM13 -b 19200

Double check connections and try again, or use -F to override
this check.
avrdude.exe done. Thank you.

The issue appears to be with the Arduino UNO as an ISP. I connected up a USBASP device and ran the following command:
and got the following response:
I have now successfully programmed a couple of the ATTiny85's with the slightly modified Blink sketch using the Arduino IDE (1.6.5)
I still have no idea why the Arduino UNO would not be working as a programmer.
