Fairlight-CMI

Hi David,

I checked and some cards have it, some don't. It is possible that the
ones originating from IIxes have the mod. I have cards coming from III
and IIx.

I also checked the manuals briefly for a mention of a mod, but could
not find it in the limited time I have right now.

Best regards,
Harald
