Martin and Mike.
Thanks for the replies but nothing changes
I have reloaded the blink program several times with differing delays and that works fine.
The programmer file (ArduinoISP_Nano_D2.ino) also loads without a problem ( but only with ATmega328 old bootloader) and the reset line is wired into D2. I have now checked and rechecked the inconnect wiring about 4 x and with an independant checker.

However it still fails 100% of the time, with the same batch of errors listed above.

Its also rather frustrating that I have Windoze on 3 PCs, but the ArduinoIDE will only program on 1, the other 2 suffer from Port not found problems that none of the dozen or so help suggestions work for !! Grrrr.

I have yet to find my USBASP programming harness to try, but I have always found that patchy with a lot of whining about drivers.

Any other suggestions?
Thanks and rgds
Barry

Aha, success, but not with the Arduino as ISP!

I found one of my USBasps, I had 2 lurking about. It works perfectly1

So I guess I'm in the 1% where Arduino as ISP fails. I'd still like a solution to get it working if possible though.
