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 came 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 6600 (on one core) | 2400 | 1555.000 | 647.92 | DJGPP 4.1.0 gcc -O3 32-bit |
New!
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...

New!
November 16 2011. I realized that I miss my dear sold "Miranda" as a good secondary computer
so I have now set up another very nice and fast Core 2 Duo machine which I came across very cheap! :-)
It is mainly used with Linux for C-programming, administration of my web pages, sometimes LaTeX
document writing and some numerical number crunching. It also has Windows XP which is mainly
used for games.

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"! :-)

New!
September 2011. Another interesting bargain I come across. I must say that my impression
of this notebook computer is very contradictory. Regarding the design it is almost a piece of crap
and it has a very "plastic" feeling and the keyboard is really bad. I don't feel so comfortable saying
this about a HP/Compaq machine, but it seems to be really low budget... On the other hand it has a
very fast and powerful Intel Core 2 Duo processor and the small 12.1" screen has very good colours
and is very sharp and clear. The weight is only about 1.9 kg (with high capacity battery) and it is
very small and handy so it is almost like a very powerful netbook.
New!
January 31 2012. Today I bought a new high capacity battery to this computer. Up to 4 hours
run time, which is very good. I have now the intention to use this computer with the Huawei E122
mobile broadband adapter (7.2/2.0 Mbit/s) at Tre (3) when I am traveling (in Sweden). But also
for home use of course and some electronics steering applications.
The keyboard metal plate was also a bit bent and "wavy" so I fixed it to the body of the computer
with nine small thin mounting pads with glue on each side. It worked very well and gave a much
better and stable feeling of the keyboard.

Here are presented some CPU and graphics benchmark results for Windows,
Linux and Mac OS X for my 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 or Mac OS X.
