Altera only mentions the ByteBlaster II for programming Cyclone devices. Presumably the ByteBlasterMV doesn't have the right voltage thresholds, strictly speaking, but I was wondering if it could be used in a pinch. I made my own from the published schematic (it works fine with Flex10K devices), and would rather avoid having to buy the II, or make my own clone of it. Leon
Cyclone and ByteBlasterMV?

Or if someone was knowledgeable about what's inside a ByteBlaster II, that would be helpful. Because at $150, I don't want to imagine what the margin on these is. The ByteBlaster/MV are models of simplicity, I hope Altera keeps the spirit.

This guy has got the schematics on his website. It is labelled Byteblaster MV, but it is the Byteblaster II though (as you can see by the name of the file). The schematics are indeed quite ... simple http://www.fuw.edu.pl/~gkasprow/ I've built the thing, and it seems to work.> Or if someone was knowledgeable about what's inside a ByteBlaster II, that > would be helpful.

I downloaded the file and got it converted to ASCII format by someone with Protel, so I can read it into Pulsonix. It's definitely a lot different from the MV - uses three '244 chips and a transistor. I'll be making a PCB for it and putting the design on my web site. If anyone else wants the ASCII Protel file I can make it available. Leon

That schematic looks nothing like the insides of the ByteBlaster II cable I had (I've just shipped it off to a client and am awaiting a new one). Nial

If I know the logic family, I can probably work the rest of it out for myself. Leon

I'm using it in the JTAG mode. Martin -- ---------------------------------------------- JOP - a Java Processor core for FPGAs: http://www.jopdesign.com/

I've done mine with 126 (to avoid the transistor used as a inverter in the schematic above mentioned) and it works just fine. Bye, Ricardo
