NetCPU or DotNetCPU DB200 anyone?

I have a DB200 that seems to be from NetCPU, or dotnetcpu.com,
though the domain seems not to exist.

Pretty much nothing comes out in a google search.

It would be nice to know the processor (it is missing from the
board, but I believe everything else is there).

A little documentation would be nice, too. 

The board has USB, serial, A/D, D/A ports, an LCD display, and
a big breadboard area to add your own circuits. Power from USB,
external supply, or 9V battery.

Would be fun to try out, but I need a little more information.

I did some searching and found this link...

http://tech.slashdot.org/story/04/12/14/0316213/a-net-cpu

which has a link to a "website"

http://www.dotnetcpu.com/

Which takes me to...

http://devicesolutions.net/

You might try asking them about it.  They seem to be making CPU modules 
and motherboards so maybe there is some compatibility still... ?  But 
this is a 10 year old product.  You could probably have more fun (and 
less frustration) with a rPi or something.

I think I found that, too, but it didn't seem to have anything
related to a DB200.

Thanks.  Yes, I haven't tried one of those yet.

From some other search, there is a hint that it might be an ARM7
CPU (as I said, the CPU isn't there).  Anyone know if they come
in a 32 pin DIP?  (Seems a rare package size to me.)

Hmmm... 32 pin DIP?  I don't recall ever seeing a 32 pin DIP at all. 
ARM7 sounds right for the time frame.  Makers from that time would 
include Atmel, NXP and a German company I can't recall.  I don't think 
Atmel produced DIPs, maybe NXP.  I believe the German company produced 
DIPs.  I'll see if I can find the name.  They were making automotive units.

Going by one comment in the Slashdot thread, it would have been a BGA 
chip mounted on a carrier board:

No, that doesn't ring any bells, but maybe this bell is old and makes 
very little noise anymore.  I want to say they had a narrow product line 
mostly around automotive.  They used bigger packages and 5 volt 
supplies.  They may have been absorbed by now.

Anyone notice the "~450,000 instructions per second"?  That is pretty 
slow even by Z80 standards.  Must be a mistake.

There is something about a processor directly executing C# code,
or compiled C# code. 

It might be the 450,000 instructions/second isn't bad if they
are complicated enough instructions.

The speculation in the same thread was that this meant CIL bytecode 
instructions.
