I have always found it weird to run diagnostic software on a C64, as a broken computer won't run it or the results are at least unreliable.
It would be far cooler to have diagnostic hardware plugged in a C64 that needs investigation, read by a 2nd C64. |

i guess these programs only helps on light damaged c64 to check ram, kernal, colors, ports and all voices is working in the sid. at least one of these program back in the days found a kernal rom failure. i didnt think the c64 was broken, i changed the kernal rom and i tested with a game where it shouddently showd the text for the trainer... with the faulty kernal rom all i could see was a black screen, when that screen appeared i just pressed the joystick button and the game begins i had no supisions about something was wrong at the time...
without this little program i wouldnt have noticed it, so these c64 diagnostic software aint complete useless...
so thats why i put a request for c64 diagnostic software...

a UK seller sometimes sells the C64 hardware diagnostic full harness on ebay.co.uk
its one plug for each port on the c64, connected with some cables and some hardware, it should be able to find any broken stuff inside the c64. |

the diagnostic program simply was stupid and didnt notice that you infact had the old buggy kernal revision :) the rom itself probably was just fine =)

no, not "any". that diagnostic cartridge is pretty simple infact. most fundamental stuff in the c64 has to work for it to work too, that is the cpu, the pla, the reset- and clock circuit, the vic and probably a few other things. faulty things it can detect is ram, rom and cias. the plugs are simple loopback dongles, mostly used to test the cias. the cartridge works without them (just cia tests will fail then). |

hey doc,
this afternoon I dug through some of my old disks and found a few test programs. There should also be one for the drive. Get the file test c64.d64 from here:

Here's a short BASIC-listing (and D64) of a SID-diagnostic program. The good thing is that it tests waveforms and filters, and it can be typed in manually when you don't have a xfer-setup.
