Fairlight-CMI

Brilliant advice guys : 

I found the following post, where a different user has a different problem (slightly) and they go to KMON diag and type DI :

http://www.fairlightau.com/Forum/viewtopic.php?p=451&sid=e7792b9128e6d693314edccf7cd362ea

If I do the same, I also get "Address Error" followed by a heap of info i dont understand.  I dont know the commands for the diagnostics, nor what this output means in real terms.

If I post a screen screen shot of the output on my system, would that help at all ?

Is there anything useful I can do with the diagnostics ?

In the meantime, Ill put on antistatic wristband, and try to resit the chip and Joe suggests.

And james, yes it is a real pity. I am accumulating quite a pile of dead cards, and im sure there cant be many left in the world ! 

Many Thanks to you,

Arron

It would be great if there was someone with the series 3 knowledge to repair these cards.  There are people who can repair the CMI-2X cards but I haven't found anyone who can repair the series 3 cards.  It's really a shame that these amazing instruments are not supported.

See if you can get your hands on a spare CMI28 would be my next goal. You might just be able to re-seat the ROMS and RAMS and the 68K in their sockets, being careful of the pins. Usually it's enough to pop a tiny screwdriver under one end, lift the chip slightly, and then squish it back down. There must be someone else in your neck of the woods with either a IIx or a series III.
