|Apr 2006||Published the chatty bootloader for the Native Oberon project. was developed for FreeDOS back in 1999.|
|Apr 2006||The Frame Stomper runs stable now so I am converting all my older pages to the new active CGI enforcer. The Frame Stomper looks if it is loaded alone. If so, it will force the loading of a dedicated index.html frame loader file. As does the link in the first line of this topic.|
|Apr 2006||Search engines got smarter the last month. They found the silly sentence that was put inside the gzipped html page (Various section). End of the Gzipped HTML project. It was fun.|
|Apr 2006||Linux at fruttenboel manor. Read all about it and as long as you want.|
|Apr 2006||When my site is approached via Google, only the main frame of a topic is loaded. So I made a frame stomper, so that when a separate frame is requested, the top and navigator frames are loaded as well. Read about the Frame Stomper.|

|Dec 2005||Due to falling visitor and download numbers, I decided to switch back to the old style of the navigator frame. No submenues, just one long listing. It's also easier for me to see what I already got and where it is.|
Started the Gameboy section. The Nintendo Gameboy Color is a small yet potent Z80 system with lots of
goodies like built-in bank switching, nice colour LCD and just enough keys for most control applications.
I have quite some plans with this nice little something....
|Nov 2005||I got a letter from my most heroic Hero: Niklaus Wirth. You can read it in the Oberon section.|
|Nov 2005||My Modula for Microcontroller project (M4M) will be halted and I will focus my attention on an Oberon compiler for Microcontrollers.|
I want to see how far I get in reviving the PICstart 16B programmer with Linux, instead of DOS. I got the
source of the 17C42 controller on board the programmer, plus full schematics for the construction of it.
This ought to work.
Check it out via 'Peripherals' and then 'PICstart 16B'.
|Sep 2005||The HP E-PC C10 now runs Debian Sarge (3.1) and all systems are GO. The HP E-PC page has been updated with Slackware, SuSE, Caldera and Debian.|
|Sep 2005||We registered WISclub.org in order to have a uniform URL that will allow all active members to set up their own subdomains. The link http://www.wisclub.net will soon be operational. We hope.|
|Sep 2005||I added a 'For Sale' section. See it as a garage sale. Only old stuff. But it might be the stuff you're looking for... Check out the navigator frame on the right.|
|Aug 2005||We removed the WISclub website back to http://wisclub.nipl.net since the (GNU) free webhost: nipl.net is back online for the better.|
|Aug 2005||We moved the WISclub website back to http://wisclub.verhoeven272.nl since the (GNU) free webhost: nipl.net has been down for too long.|
|Jun 2005||The examples from PIM are now downloadable from Pim.tar.gz on this site.|
|Jun 2005||We moved the WISclub website to a (GNU) free webhost: www.nipl.net. Nipl.net grants webservices to sincere people and groups. Apparently we are a subset of that... :o)|

I updated the pages about
|Mar 2005||I restarted reading 'Teach yourself C++ in 21 days' from page one. It's a dirty job, but somebody got to do it.|
|Mar 2005||Forget what I mentioned about GTK in the section below. After reading a few hundreds of pages of GTK tutorials, I came to the conclusion that Qt ain't half that bad... Read more about it in the GUI coding section.|
Today was D-Day (Decision Day). I came to the conclusion that my survey into the world of super structured
My new love is GTK, with some C for the time and eventually a full port to Modula-2.
|Feb 2005||I exchanged the Lithium cell, welded to the mainboard of my Compaq AP400 twin CPU workstation, for a standard CR 2032 socket. Now I can easily change the cells, when this one is drained (which ought to be so around 2012).|
|Feb 2005||I added two items to the machines page: pictures and experiences with my Longshine NIC and Longshine switches. This page is another tribute to the RTL Ethernet controllers.|
|Jan 2005||In order to be compliant with new EU regulations, I have published a page about the EUCET nomenclature for PostNine digits. This new standard is a good example of how the European Committee is pushing ICT into a new gear. Please do read this page. It will affect your and your children's future.|
|Jan 2005||Added another HPGL command summary which contains just about all HPGL commands. With short explanations. Find this file in the Modula-2 section, subsection 'Plotter', and click on 'More HPGL'.|
All Unix based graphical webbrowsers show gzipped html files as if they were unzipped. This means that I
can reduce webspace at my internet host by upto 75%.
So now I'm running some tests with this feature. Check out the first page in this range: Hello.gz which is located in the CGI section. Does this page load? Or does the browser offer you to download the file?
If it opens in a new window, check out the URL. See? The browser requested and received a gzipped file and converted it to plain html just prior to displaying it onscreen.
|Dec 2004||Added a Hello world style program written with CGI and the Mocka compiler. Check out the cgi section now.|
|Dec 2004||Added the page "C and me" about my love/HATE relation with the most used programming language of this time.|
|Dec 2004||I received the two HP E-PC's which I bought at "Now that's IT", a cosy shop in The Hague (NL). These machines were used, but working. Due to their compact dimensions they will be deployed in the livingroom and in the bedroom of my daughter.|
|Dec 2004||A small tribute to Prince Bernhard who died yesterday. He's always been the 'fool of orange', but had a great time doing so.|
|Nov 2004||I started some experiments with the Java language since it offers flexibility without the hassle of C++ and recompilation for each and every platform. See how far I come with this one after my detours via C++.|

|Oct 2004||There used to be a dutch lesson in 'Programming with the Mocka Modula-2 compiler. Now I added the english translation of this page.|
|Sept 2004||I added a 'Loose ends' page which shows circuit drawings (no texts!) some unfinished and even some unstarted projects. This Loose ends page is not big, but contains 12 PNG files so it needs some processing horsepower to put the page on-screen.|
I deleted the dutch pages for the
Parino I/O card
I added pictures about how to mount the card at home. And I prepared the site for a 'Parino with Linux'
Watch these pages for the 'PariLux' project. Coming soon to this theatre. The prototype for PariLux is already wired and debugged.
|Sept 2004||I recovered an old wannahave/gadget: the two chip DSO made with a PIC 16C55 . This product was published around 10 years ago by Parallax Inc. I found the drawing over the weekend. Now I need to recover the software....|
|Sept 2004||Added a page for checking out home made CGI executables. See it all in the 'CGI section'.|
Added a page about the computers I have here in this home. Conclusion: you can run a decent house with
Check out the 'My computers' topic in the navigator.

|May 2004||I registered http://fruttenboel.tk to make the URL shorter. I ditched it in Nov.|
Added a travesty on the popular Google search engine, which I rewrote for the dialect I talk when at home
and among friends....
Click on 'Goechul' to give it a try...
As a result of a discussion on Global WISclub some members bought a small robotic kit from Winkler
Schulbedarf in Austria. I will document my experiences with this Raupe project.
Just click on the 'Raupe' link in the Various navigator.
I registered the domain fruttenboel.verhoeven272.nl and I am rebuilding the webpages again. The main
difference is that I will tinker out all embedded E-mail references from the webpages.
Instead of many E-mail addresses in many places, I will add 'Contact Me' links in the bottom of each and every 'Navigator frame'.
There is just no really good programming language for small chips. Therefore I and some of my international friends decided it was time to do something about that. We started the m4m (Modula-2 for Microcontrollers) project.
The project has just barely started and we're at version 0.2 which CAN accept data from the commandline
and skip nested comments better than any commercial M2 compiler can....
|Feb 2004||I released version 07 of the Soup source printer which by now gets rather foolproof.|
I was disappointed that there are still no good free ISCP programmers for the PIC processor range. So I
want to designa and build my own.
Interested? Follow the link to the ICSP PIC in the navigator frame on the right side of the screen.
I added I/O port access to the Mocka compiler using a FOREIGN MODULE. So if you want to study either (I/O access or how a FOREIGN MODULE works) you can check out this page.
You can find the webpage about the Mocka IOport HERE.
In 1993 our Bravo double action airpump broke. The controlvalve housing split, which caused it to operate in single stroke mode only. And only the upgoing stroke, for that matter, which is very uncomfortable and also bad for the lifetime of the pump.
This year I repaired the pump, which is made of very hard to glue materials. Just take a look at it in the Loctite Polyolefin bonding kit page.
When I was invited to go to the zoo by the blood donor organisation of Holland, we got a single use camera
there. After exposing the film, I decided to take it apart to see what's inside.
Just take a look at it in the camera salvager page.
There's new activity in FST Modula-2 due to new members on the Modula-2 mailinglist
I ported Soup and Emit to DOS and I extended the LowLevel library with the 'Peek' command. Check it out at the FST Modula-2 programming section on Fruttenboel.
programming section on Fruttenboel.
I added the LDA program which has some unique features. QV.

This is a WISclub project since it reduces battery waste.
Started construction of the
a smart I/O systemn that connects to any computer via the COM port. Softy is meant to be used instead of
the LPT port.
Why use a 4 GHz computer with 512 Mb of RAM running a multi user operating system with full fledged security mechanisms, if the same can be done with a microcontroller with a mere 144 bytes RAM at 12 MHz?
Softy will be based on a Z8681 microcontroller with 4 Kb code and 4 Kb data memory, COM port, I2C port and a flexible program functionality.
|Apr 2003||Using the Mocka Modula-2 compiler. Made in Germany! This is a fine compiler!|
