Ooh - I thought the big gray one was the microcontroller :o)
I gues that's some sort of off-chip memory instead. Then I'm dealing with
a NEC V850 ...
Why does it have to be special NEC dev tools? Cant a generic JTAG debugger
get the code, and then I can just disassemble it in IDA Pro 5.0?

You didn't read the documents I've provided the link for.

This controller doesn't have JTAG but a proprietary ISP port, and IDA Pro
won't know the V850 opcodes. This means you MUST have the NEC tools.

From the link Frank-Christian provided I may alrady have that.
But that would mean taking the microcontroller off the board => risky
operation isn't it? I'm pretty sure that soldering it back on with my
skills will involve bridging at least 2-3 pins at a time ...

ISP means In-System programming, so the controller can remain on the board
provided that the external connections to the ISP pins and to Vpp allow
this.

See document #3 from my link, chapter 17.
