I don't see if you've ever found an answer to your questions about the CIC6124E, but I do have some information. Ignore it if you don't need it.

CIC was a spinoff company of Taiwan's International Technology Research Institute (ITRI)1. ITRI is the same organization that gave us UMC and TSMC2. It appears CIC was in operation from 1975 until 2004.

It's my belief this circuit may be similar to a BA6124, but I could be wrong. The BA6124 is a LED Level Meter driver3.

Good, bad or indifferent; I'm curious to know your thoughts on this post. I find your project intriguing and I hope this helps a little.
