Thanks Michael, EEye. As far as I can tell, Intersil's logo was based on a lowercase 'i' and then changed to INTERSIL.
Here's some more background:

This is a front panel of some unknown computer. The front plate is missing. Due the DIL connectors used, I'm inclined to belive it's from an S100 machine, but the 24 lower switches do not realy follow the Altair scheme, so maybe its from a 12 Bit machine like a PDP-8 clone. Then again, DEC also used a different switch layout. Notably the chips bear the same logo as the board, 3 lines looking like II/ There are realy no other usable markings.
So, Michael having spotted the same logo on the back side, this must be a system from an outfit which could make its own chips. I would suppose European, or Eastern Bloc. But the back also carries the annotation "CSL CONT" and the front has an annotation "SPARE" and another "SERIAL" - so that seems to be English (and in a Latin alphabet) - might not be an English-speaking country but makes it perhaps a bit less likely to be Soviet.
Maybe the sloping line is a stylised integral sign? So it's II∫
On the back side, the first I looks faint or small - I wonder if that's intended.
