Fairlight-CMI

Thanks for the advice Peter : really appreciate it. 

Im beginning to think that the channel support card is badly broken : there was a fair bit of corrosion on the solder, and it looks in a bad way. :(

Also, I found that a pin had broken off inside CMI 28 card, and so Im going to try and replace the ribbon cable terminator with one I have removed from an old CMI31 card. Im not sure this will be successful though, as the double sided board might not survive the removal process.

Anyway : enjoy your holiday, and l'll let you know how i get on :)

And thanks again for the advice .

Best wishes Arron

If you can't substitute a known good replacement, check the master clock on this, and then the two delay chips which provide the timing signals. Sorry can't remember what they're called - still on holiday, and spent the evening in a canal side bar in East London drinking the finest wines known to humanity.....
