January 17 2012. I have made a somewhat difficult decision. I realize that I can't take care of all
remarkable old computers that I come across. So from now on I will specialize on old (and new) PCs.
More information and some images of the boxes mentioned below will come soon.
Regarding old PCs I have a wonderful HP Vectra 286/12, Victor V386MX 20 MHz, Victor V486MX DX2
50 MHz, noname Intel 486 DX4 100 MHz and a nice Intel Pentium machine running at 200 MHz. Even the
slowest of these computers are fully capable of running my graphical "ssdosmix" DOS programs found
here, although not so fast of course.
Here is presented some benchmark results with my old Mandelbrot DOS program (Mflops) for these old
computers. It should be noted that that the program performs about 75 % better compiled with DJGPP
32-bit than with TC 2.0 16-bit in this test on the same machine (see the 486 DX4 at 100 MHz). The 286
computer can only run 16-bit code and a system file was missing when I tried to run the DJGPP version
on the 386 machine. The benchmark results are also compared with a modern Intel Core 2 Quad computer.
I will soon put these programs available for download together with some instructions for use. Here are the
results:
| CPU | MHz | Mflops |
Scaled Mflops at 1000 MHz | Compiler |
| Intel 286 with Intel 287 | 12 | 0.036 | 3.00 | TC 2.0 16-bit optimized |
| Intel 386SX with Cyrix 387SX | 20 | 0.127 | 6.35 | TC 2.0 16-bit optimized |
| Intel 486 DX2 | 50 | 3.200 | 64.00 | DJGPP 4.1.0 gcc -O3 32-bit |
| Intel 486 DX4 | 100 | 3.900 | 39.00 | TC 2.0 16-bit optimized |
| Intel 486 DX4 | 100 | 6.800 | 68.00 | DJGPP 4.1.0 gcc -O3 32-bit |
| Intel Pentium (586) | 200 | 49.000 | 245.00 | DJGPP 4.1.0 gcc -O3 32-bit |
| Intel Pentium II (686) | 333 | 148.000 | 444.44 | DJGPP 4.1.0 gcc -O3 32-bit |
| Intel Core 2 Quad Q6600 (on one core) | 2400 | 1555.000 | 647.92 | DJGPP 4.1.0 gcc -O3 32-bit |

September 18 2010. Just for fun I called this Victor 486 computer Crayina 1 - my incredible
"super computer"! :-) But of course the real Cray 1 super computer had significantly better
performance (especially on vectorized code). Some very good information about it is found
here.
To be fair the Cray 1 has a vector performance of up to 133 MFlops, which actually more
corresponds to an Intel Pentium II CPU at 333 MHz or so. The latter performs 148 MFlops
in my Mandelbrot fractal program (compiled with DJGPP gcc 4.1.0 -O3). The code fits into
the L2 cache of the CPU and is not able to vectorize. The Intel 486 computer at 50 MHz
only performs 3.2 MFlops with this program. I actually thought it was a little bit better...
An Intel Pentium CPU at 200 MHz performs 49 MFlops with this program, which means that
it is about four times faster than the 486 per clock cycle counted. The Pentium CPU also
has two execution units and L2 cache, while the 486 CPU only has only one execution unit
and no L2 cache. As a comparison my new Intel Core 2 Quad Q6600 CPU at 2.4 GHz performs
1555 MFlops with this program on one core. All programs were run under Windows or DOS.
Sometimes I think the computers and operating systems of today are somewhat "too good",
user friendly, streamlined and elegant and almost a little bit boring to work with. Everything
just works perfect. I am old enough to miss the good old DOS and Windows 3.11 times
when you have to spend man-days to get things work! :-) I also remember how happy I was
when I managed to set up the windows environment under Linux for the first time (autumn
1994). So just for fun I found and set up this nice and very cute Victor 486 computer from
the beginning of the 90th. The small and slim TFT monitor is of course much more modern,
but it fits quite well to this computer. An image of this nice setup as well as power consumption
data will come soon.
Unfortunately the hard drive (120 MB) seems not to work on this computer, so I have to load
DOS 6.22 into the primary memory of the computer. It works quite well and then I can easily
run my old graphical "ssdosmix" C-programs
(found here)
on it! :-)
Perhaps I will install
Windows 3.11 or even OS/2 on it if I get the hard drive to work. Note, after investigating this
further it seems as if the problem is not the hard drive itself. Actually the CMOS battery seems
to not work so the BIOS "forgets" it's hard drive settings also after a computer reset...

April 4 2013. New Melissa. Finally I came across this wonderful little Intel i5 mini tower computer to a
very reasonable price! :-) It is really very fast and has quite a lot of memory. Some π y-cruncher, SSBENCH
and graphics benchmarks for it and some other computers are presented in sections 8 and 9.
New!
April 9 2013. I have now upgraded Windows 8 Release Preview to genuin Windows 8 Pro on Melissa.
By a phone call to Microsoft Support and a quite complicated procedure I managed to "free" or "release"
the Windows 8 Pro upgrade license from Isabell (which now only needs Windows 7 HP) and upgrade
Melissa with it without any additional costs. Quite convenient! :-)

and an ambient temperature of 25 °C.

New!
January 2013. Unfortunately the motherboard on old Melissa was broken so I set up another
nice computer called Lisa with Fedora 18 Linux. The computer is used for administration of my web
pages etc and sometimes C-programming and some LaTeX document writing.

September 30 2010. Here things are changing rapidly, now to the heavy artillery.
Isabell was now changed to a fast Intel Core 2 Quad Q6600 processor at 2.4 GHz and
a powerful Nvidia GeForce 9600 GT graphics card which I actually come across by
exchanging computer parts with friends. Not even this computer is extreme at all by
today's standards, but it is more than good enough for me! :-) It is mainly used as a
good "all purpose" computer for surf, e-mail, document writing, graphics and images,
a very good stereo sound device, movie player (I have no ordinary TV) and much more
but also for games and numerical number crunching. As you can see I have now also
moved my 250 GB 64-bit Fedora Linux hard drive from Miranda to this computer.
January 14 2011 I finally installed Windows 7 on Isabell. It seems to be a very nice
and good operating system! :-) The installation was also very simple and took only
about 25 minutes. The Grub boot loader (for Linux) has to be reinstalled after.
Windows. No problems with that.
New!
June 22 2011 I made a one billion (109) digit calculation of π
with y-cruncher
on Isabell. All in ram (4.7 GB). The computer had 6 GB memory at that time. It took
1003 seconds with 96.8 % CPU utilization on four CPU cores. Perhaps I will make
more benchmarks with this wonderful program! :-)
My favorite games are wheel race with good old Colin Mcrae 04 Rally, and of course the
very good MS Flight Simulator X and good old Half Life Opposing Force. In November
2010 I also bought Race Driver Grid (by Codemasters 2007) quite cheap. It is one of
the best and funniest racing games I ever have played and it has very good graphics.
Unfortunately it doesn't work so well with my old MS Sidewinder wheel, so I actually
steer it with my Logitech joystick or the E-Sky radio control adapter. It works very
well. This spring (2012) I will of course buy Microsoft Flight immediately when it is
released. I expect it to be a really awesome "game"! :-)
June 2012. I am not a great or good action game player but I have at least now bought
Mass Effect 1 and 2 and Deus Ex Human Revolution. These seems to be very nice and
exciting games! :-) I usually take very long time to play out such games (if ever), but Mass
Effect 3 is of course also waiting around the corner. I am now also trying my wings
with Phoenix R/C Flight and Helicopter Simulator with the Aerofly R/C radio adapter
and an old cheap 7-channel JR radio. It is very funny and realistic and the simulator
has stunning graphics! :-) I mostly fly helicopters, starting with simple coaxial, but
now also learning more advanced 4-channel helis (like Align T-Rex 450).
New!
January 2013 I came across some wonderful completely excellent white active Dfeldt
Audioengine 2 HiFi speakers. They are not bigger than ordinary small computer speakers
but the sound quality is simply outstanding! :-) Two images of these wonderful speakers
are found here and here.
Each speaker measure (h x w x d) 155 mm x 115 mm x 140 mm.
Very good and handy.
New!
January 18 2013 I upgraded Windows 7 Home Premium on Isabell to sharp Windows 8
Pro for only 279 SEK (about $ 40) from Microsofts Swedish home page. It is a very good and
effective operating system! :-) I also use the free and very good
Classic Shell
start menu button
with it. I had quite much stuff installed on the computer so the hard drive was a bit slow both
before and after the upgrade. So I decided to make a full backup of the system and after that first
make a clean install of Windows 7 (from the DVD) and then make the Windows 8 upgrade again.
If you only have the license key for Windows 8 you can do the upgrade whenever you wish and
many times on the same computer. After this procedure the hard drive and the whole system
runs smothly and fast again! :-) Of course I also have to reinstall my most important programs
and put back my data on the hard drive.
New!
April 4 2013. Because of new Melissa i5 I will now sell Isabell to my mother. The computer now has
an Intel Core 2 Duo E6400 CPU, and the graphics card has been changed. Windows 8 Pro was also removed
from Isabell and Windows 7 HP reinstalled on it from the DVD. I think my mother prefers Windows 7 and
I needed Windows 8 Pro license to Melissa (see more info there). I will soon remove the computer from
this web page.

March 15 2013. Daisy is a nice DELL Inspiron 1545 nootebook computer that I came
ascoss by exchanging technical things with a friend. I use it as a good "all purpose" computer
and for some electronic steerings applications and as a good "music machine" connected
to my stereo.

Note 1. C2D and C2Q are Intel Core 2 Duo and Core 2 Quad processors respectively.
Note 2. The Core 2 Quad Q6600 processor could not run SSE4.1 instructions.
Note 3. The Core 2 Quad Q6600 processor has larger L2 cache memory than the Q9300
which makes the speed difference between them quite small in this test.
Note 4. These computers have DDR2 6400/800 memory. Perhaps the Core 2 Quad Q9300
processor could benefit from faster DDR2 8500/1066 memory?
Here are presented some CPU (32-bit) and graphics benchmark results for Windows
and Linux and some other OS for my PCs and some other computers.
SSBENCH (SIint and SIfp) is found here and 3D-Mark 2001 and 2003 can
be downloaded for free from Futuremark Corporation. Results marked "-"
are not possible to run. For SSBENCH under Windows the compiler DJGPP
(gcc) was used. There is very little difference in performance between gcc
4.1.0 and 4.3.2 under the same OS. For the 3D-Marks default settings were
used (i.e. 1024 x 768 resolution). Unfortunately do these benchmarks not
work under Linux.
Note. The SSBENCH benchmark is run on a single CPU core also on multi core machines.
