Hey, what's about Logic Analysator like the "Scanalogic 2" ?

http://www.amazon.de/Scanalogic-PRO-Ana ... analogic+2

EDIT: From the homepage: http://www.ikalogic.com/ikalogic-products/scanalogic-2/
Basic information

Scanalogic-220 MSPS (Million samples per second).
Memory: 256 K samples per channel (1M samples total).
Number of channels: 4.
Possible configurations: 4 inputs, 4 outputs, 2 inputs and 2 outputs.

Trigger options

Pre-Trigger data display: 0% to 100% (allows to focus on post or pre-trigger data).
Trigger modes: Rising edge, Falling edge, Logic change on a specific channel, logic change on any channel.

Input and output characteristics

Supported input logic levels: 2V, 2.8V, 3V, 3.3V, 3.6V and 5V.
Allowed input voltage range: -0.7V to 5.5V.
Output voltage levels: 0V to 3.6V.

EDIT: Found this link: https://www.mikrocontroller.net/article ... e_Software to http://sigrok.org :
The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types, such as logic analyzers, MSOs, oscilloscopes, multimeters, LCR meters, sound level meters, thermometers, hygrometers, anemometers, light meters, DAQs, dataloggers, function generators, spectrum analyzers, power supplies, GPIB interfaces, and more.
A list of supported devices is here: http://sigrok.org/wiki/Category:Device
IKALOGIC Scanalogic-2 is supported: http://sigrok.org/wiki/IKALOGIC_Scanalogic-2

Maybe a better choice is: "Saleae Logic": http://sigrok.org/wiki/Saleae_Logic
8 channels and 24Mhz samplerate

Seems that is cheaper as the scanalogic 2: http://www.amazon.de/Generic-Saleae-Ana ... leae+Logic
about 18€ :shock:
But the box looks different.

If you have an Arduino, you can run an oscilloscope sketch on that. Might help you verify a few things but certainly won't be great for heavy diagnostic tasks.

Have no Arduino...

My question is, whats helpfully: A oscilloscopes or a logic analysator ?
Which minimum specs (like MSPS / samplerate) ?

I get a cheap oscilloscopes (Philips PM3208 - 20 MHz) from ebay... Hope that is will be work ;)

My oscilloscope arrived today. Shipping very fast :shock:

So i need all your help. What should i check?

Btw. the 6809 CPU arrived today, too. So i can swap it.

It's repaired and runs!

It was the CPU! I buy a Hitachi 63x09E from tormod and it was in post today.

I'm happy!

Great!

Also, the 6309 is a great improvement over the 6809, which already is a very good processor.

Congrats!
