Let the games begin!!!!!
Am I the only one who is really mad about the lack
of definitive info about the vast number of controllers
out there? Well, let's do something about it! I
took a shot in the dark, and bought the GVP II without
ram, and a Quantum 105s to mount on it. The only
complaint I have about this setup is the fact that
the board seems a little flimsy to mount a heavy HD on.
In fact, the manual recommends removing the drive when
shipping your machine.
The installation is boringly simple. You put the drive
on the card, plug in the card, and use the FaaastPrep
software to Format it. What happened to the good old days,
of jumpers and ambigous manuals? :)
After seeing how the A500 version of this controller had kicked
butt in AmigaWhirled, I was eager to test it. They were using
an LPS Quantum, which are supposed to be slightly faster. Please
take these numbers with a grain of salt...I mean, look, the
times during overscan stress are higher than without! Is this
a REAL good design by GVP? Or is DiskSpeed 3.1 crap? >:)
Here are the results. All I was running was my workbench,
which has lots of background stuff like ZeroVirus and GOMF
running, but nothing like that would affect transfer rates,
right? The numbers to the right of the slash are with CPU
and DMA contention on.

Well, folks, there they are, the plain, hard facts. The thing is
plenty fast for a peasant such as I, and GVP and others seem to
support it well. I had no problems installing it (the installation
reminded me terriably of plugging in a Nintendo cartridge!) Let's
see some more cold, hard facts like this. Just try to use a
Stock (non-accelerated) A2000, with a Quantum Prodrive...the type of
drive seems to make a BIG diffirence.
Thank you, and kick I*M in the A*S....
