Hello Folks,

I would like to know your opinion about one of these
PC connected O-Scope/Logic Analyzers that cost
between $40 to $100? Have you ever used one for
our usual 8-bit computers and are they any good?

I bought this one, http://www.saleae.com/logic16 but its $300. It works real well, and with 16 channels you can scope the data lines and use rw as a trigger on another channel. They have an 8 channel model for $150 as well.

I was just about to add one of these to my shopping cart:

when this thread popped up.

The USBee looks competitive to the saleae 8 channel version, so thank for pointing that out kipp. I'll compare features.

I've been using the saleae to debug N8VEM s-100 boards, as well as some original s-100 boards I have. To see a description of the unit in use, John Monahan's site: http://www.s100computers.com/My%20System%20Pages/Z80%20Board/Z80%20CPU%20Board.htm
Has some nice pictures.

I've got an Open Workbench Logic Sniffer (http://www.seeedstudio.com/depot/open-workbench-logic-sniffer-p-612.html) (but I haven't used it much). It's quite cheap, and it uses the open source SUMP (http://www.sump.org/projects/analyzer/) software. The Logic Shrimp (http://www.seeedstudio.com/depot/logic-shrimp-v1-logic-analyzer-p-803.html) is even cheaper.

Some of the DP (Dangerous Prototypes) tools look to be pretty good.

But I'd still look for a good used scope if that's what I wanted. It's hard do design a really good fast digital oscope. Logic analyzers are a different matter.
