Re: Testing bus transceivers

Testing bus transceivers

So, I have bought a number of DS8641 bus transceivers from a source in China, and cognizant of the claims that there are a lot of counterfeits coming from China, how can I test them to make sure the meet specs? I have a QBUS test board which I have constructed (it's basically just a single

While copying some data from a bunch of Next HD's, i stumbled upon a snd file containing a song written for Steve Jobs, accompanied by guitar and handclaps from several people. Is this a known song? I was unable to find a better version on the web than the 8012hz sample I have here. -- Met

Between the CBM and CPM machines, this lot is exactly the stuff I'm into.. I'd gladly take the whole lot - don't suppose the OP is anywhere near St. Paul / Mpls? On Mon, Nov 16, 2015 at 1:52 PM, Kurt K wrote: > Can you post your location to see if in driving distance. > > > On
