Maybe I am blind but I don't see any candidates for a Lattice PLD (except maybe the small clock generation device next to the ADC and sample FPGA).
When in the teardown was this? and was he talking about the DS2k?

keyboard/leds on the frontpanel

Duh... That makes sense yes.
Not so interested in that I guess, must have been absent minded watching that part.
Carrington:
Is this correct?
IMHO would be interesting know the entire table, and thus activate the desired options with a single key.
--- Code: ---Code table: Use DSYX for a official key, and use VSYX for a trial key.
Y CAN, 300, 50ohm
A none
B == == on
C == on ==
D ?? ?? ??
E on == ==
F ?? ?? ??
G ?? ?? ??
H on on on
J ?? ?? ??

DSA9 through DSH9
=====================================================
D S * 9 AT DC CAN MD 100 200 300 unknown
A ON ON = ON ON ON = =
B ON ON = ON ON ON = *
C ON ON = ON ON ON ON =
D ON ON = ON ON ON ON *
E ON ON ON ON ON ON = =
F ON ON ON ON ON ON = *
G ON ON ON ON ON ON ON =
H ON ON ON ON ON ON ON *
--------------------------------------------------------------------------------------------------
I have not found what * dose yet.
The "*" unknown option dose not turn on 50ohm for my DS2072 HW 2.
-------------------------------------------------------------------------------------
Also tried DSI9 through DSZ9. Got license unavailability. I'm guessing its not a good idea to use DS*9 option same as before.

eV1Te:
New firmware is out for DS1000Z, version 00.02.01.SP1
It has quite a lot of bug fixes and seems to have faster GUI as well. :-+
Now its possible to export the full memory of points as wfm files, but I have not found any software that supports these files, either to open or convert them... Does Rigol have any software for this?

Nice, can you please share the file?
