ALB and Pascal

Posted by ALB42 on 11. September 2018No Comments

Hey ALB do you like all old computers or only Amigas.
 
Let’s say so, if there is a Pascal compiler for it, it’s counted as a computer worth to care about. 🙂
 
So I present to you, a pascal compiler on a old GDR (east germany) computer KC85/4, a real machine, not emulator. Signal converted with the Extron and recorded using the Elgato device mentioned before. Basically just a testcase for the conversion/recording equipment

and another little pascal test program 🙂

Just for fun.

ExtronControl for Extron DSC 301 HD

Posted by ALB42 on 31. August 20182 Comments

I bought that device, its a very nice scaler nicely usable for old computers to bring the image in a good quality to modern monitors. I supplies a serial interface for controlling (beside the on screen display) but only a Windows program to use it. I wrote a little program to operate this device from Amiga/MorphOS (where you can use the USB connector at the front panel as a USB2serial bridge). Already working very nicely, some screenshots.

You can switch the inputs, it shows which input is selected (it also notice the change when you using the front panel). When an input has a usable signal the button is printed in bold. It’s an very early version but works already nicely, if someone it interested I just make a download available here (binaries for Amiga68k and MorphOS and the full source, licensed under CC0, it needs the last MUIClass package to compile, just yesterday I fixed some bugs there, should also compile for the other Amiga platforms) have fun.

Capturing MorphOS

Posted by ALB42 on 23. Juni 2018No Comments

Until now I always used VNC remote desktop to record MorphOS Videos of my FreePascal programs. I already bought before a standalone capture device but it did not work, even I set the screen mode to 720p or 1080p the capture device do not recognize the signal and therefore does not record anything.
Now I got an “Elgato Game Capture HD” with this it seems to work when you set the screen mode in MorphOS to “1280×720 (50 Hz, 37.5kHz) 720p” the 60 Hz seems not to work.

Sodoku for Workbench 1.3

Posted by ALB42 on 16. Juni 20182 Comments

I packed Sodoku as an ADF, not bootable becasue it needs intuition.library, so you have to load Workbench first. It needs around a 1.5 Mb RAM. Sadly I still not get the newer FPC Version to work (strange crashes, looks like some memory corruption, because it always crash at different positions) so the executable is still rather huge (550 kb vs 52 kb) and therefor needs a lot of memory to load it.

Playing on Workbench 1.3

Posted by ALB42 on 15. Juni 2018No Comments

I dig out my old Version of FreePascal for Workbench 1.3 and I tried to use it with the latest FreePascal, and it seems not to work. Thats bad because the smaller exe size was after that, so the executables are still quiet big.
So I should check again how to do that.
But first I played a little bit with it and wrote a little Game for the Workbench. A Sodoku which worked quiet nice, just the graphics is rather difficult because many of the convenience feature to create Bitmaps and rastports and so on are not there so you have to do it by hand.

But finally it works:

25 years of FreePascal

MAybe you do not know it but FreePascal turned today 25. On 8th June 1993 Florian Klaempfl started with current FPC source base.

I will take this opportunity to say thanks for that. It’s an awesome program and becomes better and better Also thanks to ChainQ which gave me the the chance to use my favorite language on my favorite computer system.

Happy Birthday FPC 😀

MUIMapparium AGA on a native Amiga

Posted by ALB42 on 31. Mai 2018No Comments

I tried the MUIMapparium on my real Amiga 1200 with 680030 50 Mhz (With 68882 FPU). Good news, it works somehow, of course it is slow but once the images are loaded, it moves ok. Unitl now it freezes a little bit when release the mouse button… maybe I should try to find the reason for that.
I also tried on a 16 color screen, much faster… but looks awful 😉 so I decided to make the Video with a 256 colors screen 😉 even it’s slower.

MUIMapparium AGA

Still playing with Datatypes in principle not so difficult, maybe could make it a little bit easier with some wrappers. The Datatype system even take care of scaling the image to the actual screen depth and dither the image if needed.
Until now MUIMapparium need a 15Bit+ Screen because I use Cybergraphics functions to draw the stuff to window. But when loading the pictures with the Datatypes it would even run on an AGA screen with less colors.
I gave it a try and the first version works rather nicely.

Of course it’s just a ugly hack until now, not at all optimized and maybe even crashing or eating memory. But maybe worth investigating a little bit as alternative.

MUIMapparium 0.7

Posted by ALB42 on 18. Mai 2018No Comments

As announced yesterday I release today the new version of MUIMapparium. It’s 0.7 now, most important features are the repaired Search function, Exports and the PhotoList

Change List:

  • BugFix: Search Function
  • BugFix: Saving Route without calculating a Route
  • Set current maps position and zoom as start position for the program
  • Remember open status and active page of Side Panel
  • Configure Color of WayPoints
  • Export Map as PNG Image
  • Export Route as HTML File
  • Export TrackPlot as PNG Image
  • Export Track as HTML File
  • Load EXIF of Photos
  • Show Photo position on Map
  • Simple Photo viewer
  • AREXX commands for adding photos to list
  • Help for AREXX commands

Download at MUIMapparium Page

I added some debug output at AmigaOS4, so if you experience problems starting up MUIMapparium on OS4 check the debug output (e.g. Sashimi) it should count from 1 to 26 on the bootup, check if any numbers missing and send me the result on one of the forums I’m usually on.

Search MUIMapparium Photos

Posted by ALB42 on 17. Mai 2018One Comment

Worked on the broken Search function, I guess I will publish this tomorrow, the new functions are not finished but without the search function the program is more or less useless. The new function is the list of Photo with EXIF GPS positions, as Mapparium also had. It can use Datatypes (need jpg Datatype of course) or the internal pascal JPG loaded, which seems to be slower most of the time, especially on big endian systems. The photos are grouped by date if you double click the date entry it try get all photo markers in sight, when clicking on a photo it shows it.
