SkyChart from 1990
« on: December 16, 2020, 04:39:50 pm »
There's a tiny nice program SkyChart which has been written for OS/2 1.3 in 1990. It still works on current OS/2 systems:
http://www.hypermake.com/english/favorite.html
then press "SkyChart".

The program shows the night sky on a specific location and a specific time.

But there are two bugs:
- Date bug: the current date is 2000 instead von 2020
- Resolution bug: Screens larger than 1920x1200 immediately crash the program.

The authors are Hans Bloemendaal and Klaas van Ditzhuyzen, Netherlands. Does anyone has still contact with them? If I get the source code, I could try to fix the two bugs.

I like the program more than current Windows programs, because it is so simple.

NightVision OS/2 has already all the functions of SkyChart and more. But if you require access to a larger star data base, there is a Java version 5.2 which runs very well in OS/2.

Hi
The authors are Hans Bloemendaal and Klaas van Ditzhuyzen, Netherlands. Does anyone has still contact with them? If I get the source code, I could try to fix the two bugs.

I'm trying with a couple of Hans Bloemendaa I found on LinkedIn, let's see if they reply.

Hi Martin

Hans Bloemendaal contacted me back. He does not have the source code and Klaas van Ditzhuyzen used to be one in charge of OS/2 development. He haven't contact Klaas van Ditzhuyzen since 1990, but sadly a friend of him mentioning Klaas decease about 15 years ago.

Sadly, I think we have no chance to get Skymap source code.
