bought some of these to maybe find out way they are.. pretty anyway 
the MOS chips are marked MCC 5501 and are dated from late 76 to early 1977
If anyone has any info it would be greatly appreciated 
When i do get them shipped to me.. I will open and see what markings are on the die

It is MCC I can confirm
All the chips I have are marked as follows
MOS (logo)

| This IC is used as a keying LSI in Conn electronic organs and is scarce. I have 2 Conns using these and each IC switches 1 octave. I also suspect one is faulty but haven't yet diagnosed which one. An equivalent appears to be MOS K07 2400. I have 21 of these in one instrument (Conn 644). |

| I ran across this thread looking for information for these chips I had stashed away over a decade ago. Is there any information posted online about them? From my searching, I always just end up back at two threads on this forum |
