Default Converting a ByteBlasterMV into a ByteBlaster II?

Argh. I just discovered that my ByteBlaster MV clone can't program an EPCS
configuration PROM, but the ByteBlaster II can.

Google led me to a web forum that suggests an MV can be converted to a II,
but I haven't been able to find any details.

Does anyone know if it's possible to convert a ByteBlaster MV into a
ByteBlaster II, and if so what the details are?

Thanks,

-Nevo

A brand new USB-Blaster from the people that make it for Altera is US$
80 delivered.

I would thing the conversion process would be:
1) Sell old one on eBay.
2) Buy new one.

A true ByteBlaster II is built up of discrete transistors to be able to
program the really low voltage targets. The MV uses HC logic buffers.
If I remember right, the II also has 2 more control lines than the MV
and a slightly different pinout. Each one is also "keyed" with some
unused IO pins shorted to allow detection by Quartus.

Your best bet is to build a II-clone with HC buffers. It's only a few
dollars in parts. I put one on this board:

In the PDF schematic it's on the upper left. Many of the values aren't
critical.

You could convert an original ByteBlaster to a ByteBlaster MV just be
changing the eight-bit buffer in it (from an LS to an HC family I think).
However, as others have said, the ByteBlaster II is a different beast with
extra features.

You can buy very low cost Altera Byteblaster II clone. It is only
$36.95 USD.
Don't waste your time and money.
