|  My Experience with the Diag 264 cartridge
So most of you know I have been having problems with my plus 4 machines and more recently with one of my c116 machines. Now the plus 4's I can deal with but the c116....
So I downloaded the Diag 264 rom image, burnt it, plugged it into a C16 tutor cartridge and plugged it into the c116. At first it did nothing, so after numerous plug and unplug routines, it finally worked and what do you know, it actually really does diagnose problems 
I discovered the Kernal was bad, so downloaded one of those onto a new 27c256, plugged it in and all good again !
Now onto the next sick patient

A C16-Tutorial Cardridge is relatively rare. I havent seen many. A pity you wasted one, i was searching for one...:)

"it finally worked and what do you know, it actually really does diagnose problems "
What exactly were you expecting? 
If you have the ability to burn a prom, I would suggest you burn the kernal version and use that to diagnose machines that don't boot as it's much better at diagnosing ram problems. The cartridge version needs the ram and kernal to at least be partially functional in order to hand over control to the cartridge, so you were actually quite lucky.
Glad you found it useful. Rob

Thanks Rob, I will defenitely try the Kernal version as it seems to be much more powerful / useful, having lots of 264 series machines, this tool as absolutely invaluable!
