Additional RAM to iMac and installation of some software and games

RAM upgrade

After Mac OS 9 updates I started to use this system. But after a short while I realized that I really need more RAM. It was almost impossible to work with more than one application. Therefore I was decided to buy 512 MB RAM.

I knew about one small shop with old computers on Favoritenstrasse (U6: between Taubstummengasse and Südtiroler Platz). I went there and asked about SDRAM PC100. Old but nice guy showed me some 512 MB modules for about 30 €. I didn't have so much money with me at that moment and I also wanted to visit that Mac shop once more. So I left the shop and forgot my umbrella there.

That Mac shop offered me the same kind of RAM for about 45-50 €. Hmm, .... No thanks. I went to my room and picked some money from bankomat. I returned to the computer shop and the seller offered me (except my umbrella - for free of course) one module for 24 €. It has not been tested yet. I have bought it and put in my iMac - and nothing happened. Bad, but I had to go to the school. After my lecture I went to the shop again and changed the module for another. This time it was Kingston for 27 €. But I didn't have to pay at that time. I inserted the RAM as before and it worked!

The RAM slots in the rear of iMac

I have 512 + 64 = 576 MB RAM now. For Mac OS 9 it should be enough. I have also turned the virtual memory off. The increase of speed is evident, especially when I use more applications at once. Now I can use Mac OS 9 with more pleasure or with pleasure.
(Of course I went to that shop once again on the next day and paid the rest :-))


I don't like Internet Explorer but it seems that it is the fastest and most stable browser for OS 9. I tried iCab 3 and Mozilla but iCab was very slow and Mozilla very buggy. I have installed Internet Explorer 5.1 for mac and I use it as my primary web browser.

I have found iTunes 2 for OS 9 and installed it. It runs quite nicely and finally I can stream radio.

I have QuickTime 5 but what about Windows Media Payer 7? I don't know if I will have to use it but for every case.

Acrobat Reader 5 is also a good choice. It seems a bit faster than version 4.


This iMac is not a gaming platform for sure, but I wanted to test and see the abilities of graphic card.

As a first game I tried Diablo II demo. I have adjusted the resolution and the video renderer as RAVE because of "3D" environment. Game runs smoothly at 800x600 resolution (millions of colors), it's quite playable.

Second game was Quake III demo. It is one of my favourite games and I was wondering about how will it run. I tried many settings and the best in my case is 640x480, 32 bit (16 bit is even faster but I don't like it), texture and geometric detail low. It can seem very ugly, but when you play it is OK on iMac display. Of course it is possible to have better resolution and image quality but I like Quake to run as fast as possible.

The third game I want to mention is Warcraft III demo. This game ran at 640x480 with 16 bit color depth. It was playable but not for me. Actually my iMac does not even fullfil minimum hardware requirements.

#covid19 in the Upper West Side

As of today, New York’s total death toll rose to nearly 3,000, double what it was only three days earlier. The total confirmed cases in the world is 1,141,190 and more than 57,000 of those are in New York City alone. The news is full of sad stories. My family and friends are asking me about the situation in the city on a daily basis. It must be shocking for them to watch the news aboutNew York. But, in fact, how is my life in the Upper West Side?

My last day of work before this lockdown period was March 16th. That day, I gave some data to my colleague, packed my desktop computer in my hiking backpack and walked the 20 blocks home. A lucky move, because a few days later, our institute officially closed their doors. Since then, Mia and I have lived and worked together in my/our apartment, which is around 20 square meters large (200 square feet), in the Upper West Side of Manhattan.

Since Mia and I started dating, we had a rule to live together only after our engagement. We both wanted t…

Windows 7 RC Ultimate on HP Compaq nx6110

I have never tried Vista on my laptop, because it is well suited for WinXP and I don't like Vista. But what if you can download the new Win 7 RC for free?

I'm using Windows XP since I have bought my old laptop HP Compaq nx6110 (1,4 Ghz Celeron M, 768 MB RAM). WinXP runs on this laptop really fast and smoothly, but I have turned every "eyecandy" off and it looks like old Win95 now. But I like this neutral look.

Last week I was closed in my room for two days installing and trying different Linux distributions. After this time I ended with Arch Linux installed on my hard drive - system was stable and either WiFi worked well. Then I realized, that I have spent so much time and done nothing useful. So I decided to work with WinXP and don't bother with other OS (like 2 weeks with Mac OS X a month ago).

But NO. Incidentally I got to this website and started immediately download the iso image. The download process ran in Java and I had download speed about 800 KB/s, that…
