I scanned the IMFC manual some time ago, which can be found here:

May I ask where this information was found? I haven't found any number like this on my card, but then I don't have any of the IBM part listings either.
And does this number count for both revisions of the card?
I imagine so. I don't know that there are official additional "revisions" besides. The main differences I've noticed between cards consist of mask vs. EPROM usage, and small differences in the analog output stages.
Hi Jim. I have a few questions, if you don't mind...
The IMFC, unlike Yamaha's FB-01 module, features a "chain" mode, allowing the card to pass additional notes beyond its polyphony limit to the MIDI OUT (to another IMFC, or even an attached FB-01). Was this feature added by request of IBM, or is it something that Yamaha did independently? Any idea if this feature ever made it into an FB-01 ROM revision?
Are you familiar with the problem of trying to run Yamaha's IMFC-intended "Compose" and/or "PlayRec" programs in a system later than an XT (386+)? The KAPI driver used by these two programs attempts to generate and read an IMFC interrupt, but despite the interrupt getting generated, the driver never sees it, and the programs never start as a result. Was this issue ever discussed on the IMF forum, to your knowledge?
The IBM Music Feature Card was an 11" card and the last IBM PC where they could be installed was an early PS/2. I never had access to a PS/2 to try out one of my IMF cards. My personal experience was with 5150, 5155 & 5160's. I said in my post that I had 7 of the cards but I had miscounted - I have 9 of them. Four of my cards are in a pair of
5150's that I am about to sell. These two 5150's were in storage for more than two decades and when I retrieved them they worked perfectly! When my youngest son was 13 years old he preformed a music show where he was the only human in his band, The rest of his band was in the IMF cards! BTW- it took a 3/4 ton van to carry the two of us, the stage, the computers and a bands worth of amps, mixing boards and audio. It was a fun time for both of us. We only used "Compose" (although we could demo some "Playrec" tunes). Thanks for your reply! There was hardly anything said in the forum about Yamaha's FB-01. I wasn't even familiar with the MIDI chaining process. Also, I do not recall any mention of the KAPI problem that you described. Sorry for my awkward replies. I am still learning how to use this forum.
