Thanks, Nial. I think someone else mentioned something like that.

Leon,
From memory it was a sea of transistors on both sides with an 8 pin
SOIC on one side.

The drawback is that BBMV can't program EPCS devices....

I output it from Pulsonix as a PS file and converted it to a PDF:
http://www.leonheller.com/bb.pdf
It really needs the colours changing on the imported schematic to remove the
black areas, but you should be able to follow it.
I'm not sure if it really is compatible with the BBII, I'll try my BBMV
clone on the Cyclone first and see how I get on.

Could You please send us a copy of the converted BBII schematics in a
readable form (*.Bit, *.PDF, *.gif, ...) or make them available on the net?
Think a specialized format is not good for publishing ...
-Thanks.-

Thanks, I'll try it. I suppose it could depend on how the I/O banks are
configured.

My local FAE told that the original BBII uses transistors for it's logic
due to the 1.5V io requirement, but if you use 3.3V IO, it's perfectly
possible to use som 74's to do it. I've done mine with 126 (to avoid the
transistor used as a inverter in the schematic above mentioned) and it
works just fine.

The ByteBlasteMV works quite well with the Cyclone. I'm using it in
the JTAG mode.

What chip(s) did it use? If I know the logic family, I can probably work the
rest of it out for myself.

Eric, what programming format did you use?
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).
