The cbm3000 had a relatively short life around 1979/1980

I'm using this product: http://dangerousprototypes.com/open-logic-sniffer/

I give up this product is hell, loosing the usb serial port (need reboot each time it is disconnected)
The documentation is poor, browsing a lot of web pages to find some elementary information's

Apparently the vhdl code for this specific model is not available
(I wanted to check the .ucf file to find the information I needed)

It is brand new but one channel is not responding...

Finally I lost my time and my money...


I should have bought a 32 channels zeroplus
I have a 16 channels it works wonderfully

Aaah, I see - I've never seen a CBM3xxx model - only the CBM2001,40xx,80xx models

Still, if you are looking for help on the list - it would help if you told what brand of logic sniffer you are using...
