OK, I got a 6.4 GB laptop drive hooked up and right now the iOpener is running
DOS/BATCH V10-01A on an emulated PDP-11/40+RK05 system. I love it!!!
It's going to take some real butchery to get the case closed, but I guess
that's to be expected. The low-profile 3M connector barely fit under the
CPU heat sink w/o needing it to be clearanced, that was nice.
BTW the CPU seems to be 200 MHz, not 180 MHz. But it still gets only about
80 BogoMIPS, pretty slow.

Argghhhh! The indignity of it all! I still haven't heard from CC about the
one I have on order. I just hope when I get it, it isn't one of the new
"Hacker Proof" ones they've supposidly started manufacturing as of this
last

First of all, BogoMIPS are exactly what they are named: Bogus.
Second, the is not realy related to the real world speed.
The WinChip C6 is more or less like a P133-200 MMX, depending
on the Task, while the WinChip2 acts more like a P200-266,
especialy when applications are using the 3DNow! operations.
I have a WinChip2 system running at 266 MHz and it performs
well enough. I just replaced the old P133 by a WinChip2.
With DirectX and the acording 3DNow! enabeled drivers even
some new games do run at acceptable speed.
The WinChip2 is for old Pentium systems what the AMD 5x86 is
for 486 boxes - the last big push.
BTW, if the CPU used is a C6, an upgrade to a WinChip2 is
a real good ise - costs avbout 50 USD, and gives about
50% more performance - see

But the cool thing about the machine is that it works at all, it's not
supposed to be fast. Now that I've cut holes in the case and RFI shield so
I can reassemble it with the disk hanging out the back (for easy swapping),
the screen has developed a blue line up the middle, which is kind of a bummer.
I hope I just pinched a cable or the HDD connector is flexing the mobo due
to slight interference with the heat sink, it'll be a shame if the line is
here to stay.
The iOpener keyboard is kind of cute, the keys across the top have crazy decals
but apparently they really are F1-F12 as usual. And the Tek 4105 style puck in
the upper right corner seems to emulate a PS/2 mouse (the two rubber buttons
on the left are the mouse buttons), so it works fine with Linux using the
usual PS/2 driver. Even the autorepeat rate can be programmed as usual, it
really seems like the whole machine is surprisingly PC-compatible, considering
it's running custom software and the hardware could have been anything.
Has anyone heard anything about how to program those two LEDs on the top of
the screen (i.e., you've-got-mail and phone-line-in-use)? I'd love to use them
for a NULJOB display... :-)

The problem with that reasoning is that BogoMIPS aren't an absolute
scale of *anything*. There's a different "correction factor" that gets
used to scale the number depending on what kind of processor the kernel
thinks it's running on.
Given only two BogoMIPS numbers from two systems, it's not even possible
to infer which processor is faster to run the BogoMIPS loop.

Well obviously, but just because the BogoMIPS numbers

Well, lets face it, the BogoMIPS is like the infamous Norton SI.
worthless when comparing speeds. Take a look at the sources, and
you'll see that is doesn't do any good.
BTW: can you please check if it's a C6 or a WinChip2 inside you machine ?

I hope someone is comeing up with replacement key caps
(especialy for the German Umlauts :)
