My breadboard ISP programmer started falling apart, and I would often bend the pins on the ATTINY85 plugging and unplugging repeatedly while working a project. I took an hour this morning and soldered up a permanent programmer circuit. There are number of good online tutorials for how to do this. Here is one I used as a refernce: Hao's Blog - Programming ATtiny85 with Arduino Nano (Note: for the sBitx SWR Bridge we use a different board manager core than the one Hao demonstrates. See my blog post KK4DAS - Amateur Radio Explorations: Homebrew sBitx - Power and SWR Meter Working for details.) The official Arduino document for using an Arduino as a programmer is here: Arduino as ISP and Arduino Bootloaders | Arduino Documentation
This worked straight away - its great to have a soldered up board - and with the zero insertion force socket - no more bent pins.
