Any help would be great.

Thanks
looks like that was the problem

It compiles fine now but there is an issue with uploading says problem uploading to board, i even tried with old bootloader......im going to try with another board in a bit and report back.

Ok all good now....had the wrong programmer selected but all working now.
Thanks for the help

I have followed the instructions, i have successfully compiled/uploaded to Nano, Double/triple checked my bread board setup including tracing pins to Arduino pins and i cant seem to get machine to boot.
I'm using a working sb100 board with 6800 removed and with wire attached to pin 4 where 6800 chip goes.
Am i missing something here....do i have to do something special after uploading Arduino?
I was also curious each time i upload sketch to Arduino do have to erase old sketch or does this do it automatically ?.I'm fairly new to Arduino boards.
Does it matter if original roms are installed in board as well or do they need to be removed?

Here’s a couple pics

Thanks fir the help
