Old Hardware Emulating - The Continued Evolution Of Symbian

 

The Nokia S60 Platform Continues To Evolve

By the middle 2000's, the Symbian-powered handhelds made by Nokia dominated the marketplace once held by Palm. The PDA was evolving into the smartphone, and Nokia was in the middle of transformation. Symbian was rapidly evolving to meet the needs of these new users. The smartphone continued to get bigger screens, along with full physical keyboards. The user interface of Symbian was revamped to accommodate these changes.

However, their really isn't much to say about the base OS. The applications included were very basic and standard. The bigger-screen devices featured bigger icons, just like PalmOS. The launcher could have different themes. Their was a multimedia viewer that supported both JPG and GIF icons. Again, by 2006-2007, this was the norm.

When it came to multimedia, their were limitations within the Nokia SDK Emulator. MP3 Playback didn't work. The codec wasn't included in the device simulator for licensing reasons. As such, for music playback, MP3 files needed to be converted into the AMR audio format that is supported by the SDK.

According to the Symbian SDK in regard to supported multimedia formats, the AMR audio format is a patented audio data compression scheme optimized for speech coding. This is the audio format used for people doing voice recordings. As such, the audio quality isn't that good obviously, with a 8000 Sampling Frequency at 12.2 kbps and Mono sound. However, I don't think that this was an issue on real hardware that supported MP3 playback. One can still carry their Beatles with them on the go! However, a typical 2-3 minute song encoded in this format will typically range between 300-500KB in size, which is small enough to fit on an floppy. One can be a sucker for AM-quality audio though!

Video playback is possible on the SDK via RealPlayer Mobile. The S60 platform supported the 3GP mobile video format. This was the format used on various flip-phones of that time, like the Motorola Razr. Video encoded in this format conformed to the resolution of 176 by 144 pixels at 15 FPS. The audio source is the same as AMR (8000 sampling frequency, Mono sound at 12.2kbps Audio Bitrate). However, video playback on the SDK was relatively smooth considering the constraints. 

While one could laugh at the video specifications from today's perspective. However, one has to remember that video playback on a handheld was still largely a novelty in the middle 2000's. The smartphones of the day had massive hardware constraints. One couldn't expect HD video given these constraints. The fact that video playback could even occur at all was actually something of a major feat at the time.

The SDK was installed on a VMware virtual machine running Windows XP SP3. This would have been what most Nokia developers would have used as their development environment by the mid/late 2000's. The virtual machine had a single core allocated to it along with 1GB of RAM. WinXP isn't that well optimized for multi-core processing, and thus, a single core is generally recommended for software compatibility. Also, the SDK really doesn't need massive amounts of RAM anyway, and WinXP runs well within 1GB (minus games). The host machine has 16GB's of RAM and a AMD-FX 4300 Quad-Core CPU with each core running at 3.8GHz. Again, from the SDK's perspective, their is a lot to work with. 
On the whole, their wasn't much to say about the base SymbianOS. However, one could write books about the exploding software library that was starting to surpass even Palm by this point. Applications developers the world over embraced Symbian as the mobile platform of choice. The S60 SDK included the J2ME (Mobile Java) interpreter that would be used by thousands upon thousands of applications, especially games. The SDK became a very valuable tool for software developers, a role that it fulfilled very well. The 3rd party software scene will be explored in the next article. Nokia took the ball from Palm and ran wild with it!

WeatherStar 4000 Simulator For Windows (Part 1)

Image
  It's time to get the weather forecast, 90's style. A couple of months ago, I reviewed the WeatherStar 4000+ simulator for web-browsers. This simulator, created by Mike Battaglia, is a open-source, on-line simulator of the WeatherStar 4000 hardware used by The Weather Channel during the 1990's. This simulator ran without issue on both Firefox and Chrome on Windows 7 (Home PC) and Firefox on Windows 10 (Dell Optiplex).  It also runs great under Chrome on my Android devices as well. I use the online simulator when I'm on the road.  Now, I'm going to look into the WeatherStar 4000 simulator for Windows offered by Taiganet. This simulator offers a lot of features and can be customized in various ways. When I'm home, I use this program most of the time. Now, there is one notable hardware requirement. First, to run the Windows (and Mac OSX/Linux ports as well) simulator, you will need a computer that supports OpenGL 3.3. My home computer ha

My Thoughts Close Of The Election : Religion and Politics

Image
  One of the most toxic things that anyone can do is mix religion and politics together. Why Do People Mix Politics And Religion Together? Even on a good day, politics is a very divisive topics. In theory, a political discussion shouldn't be charged. However, when people feel that there preferred party can do no wrong and assumes a us-vs.-them mentality, then a rational discussion flies out the window. You can only imagine how things get during an election year.  However, one of the most toxic things that anyone can do is mix religion and politics together. When this occurs, the object of worship changes. Instead of God, people start to worship politics, and thus, there preferred leaders become there new gods. The level of devotion is still there, but the direction changes. Political ideology is passed off as quote "Biblical teaching". This party becomes quote “evil” while this other party becomes quote “the party of God”. Things become black-and-wh

Old Hardware Emulated :Psion Model 3a Emulated On DOSBox Windows

Image
  Psion 3a and 3c Psion Series 3c Handheld Computer (Wikipedia) Psion 3a As mentioned in the previous articles, the emulators for the Psion 3 exist only on DOSBox. I decided to take the challenge of setting up a emulated configuration. What must one do. There is already a very good guide on the internet titled "PocketBook II emulation..." which is linked below in the article. Highly recommended. Setting up a emulated Psion 3 takes a little bit of effort, but it's possible and is a good exploration of setting up a DOSBox configuration. I'm making the safe assumption that the fast majority of those reading this are using Windows systems, but DOSBox has been ported to Mac OS X and Linux as well, so this guide might work on those systems.  The first thing I did was created a folder called dosbox_psion3 (Folder naming is based on personal preference). Make the following new folders within dosbox_psion3; psion3, a, b, and m. With the f

Classic Systems Emulated: Windows 3.1 OEMS

Image
  The OEM's Want In On The Action The PC Market of the early 90's was a very competitive one. As such, having a easy-to-use environment was a must for these companies pushing there hardware. Hardware has caught up to software, and as such, it was now time to push the command prompt out of the way for the GUI. Several of these companies spotted opportunities to make  deals with Microsoft to pre-install Windows on there computers. This phenomenon didn't start with 3.1 though. Even in the late 80's, both Compaq and IBM often preinstalled Windows 386 for corporate customers that brought there 386 systems. Windows 3.0 was bundled with a lot of systems too. It was preinstalled on the IBM PS/1 budget PC's and various Tandy models. It came with the Amstrad MegaPC and various other PC's offered by ZDS (Zenith Data Systems) as well.  The number of OEM partners grew with the Windows 3.1 release. Some of them were familiar faces, like Compa

Old Hardware Emulated : Pocket PC 2000/2002

Image
  Windows CE On The PDA Pocket PC 2002 starting up. For the remainder of the 90's, Microsoft had a tough time gaining a foothold in the handheld market. Windows CE 2.0 was well received on the palmtop PC's. However, that market-share was small compared to there PDA counterpart that were rocking to the tune of PalmOS. The first incarnation of WinCE on the PDA seemed sparse compared to Palm. At this point, the PDA port of Windows CE was re-branded as Windows Mobile. Around this point, Microsoft's fortunes began to change. For the first time, the Palm platform had that "Oh Crap!" moment when Compaq released the iPAQ in April 2000. The PDA came with the new Windows Pocket PC 2000 operating system. This version of Windows CE was specifically geared towards PDA's in particular. The iPAQ line of PDA's became must own devices for those that wanted the latest and greatest. As how Compaq made IBM look silly in the 80's and 90's

Some More Thoughts Of Greg Abbott

Image
Sometimes, one wonders whether being a Texan is more of a curse than a blessing. This is the impression one gets when living in a state run by Greg Abbott. Yes, it's going to be another one of those articles. However, I did take extra effort to try to tone down my sentiment. Anywho, it's often said that a person's true colors shows when their is deep adversity. A person will even swim or sink depending on a situation. As such, I really didn't have an opinion of Abbott pre-virus. Sure, he said a few stupid and obnoxious things before the outbreak. However, all politicians do that, so that's not anything out of the ordinary. The only thing I knew about him was that he was the governor and that was about it. After witnessing his responses to both the outbreak and the 2021 freeze, I have an opinion on him now, and its not very positive at all. Calling him an monster would be an understatement. A part of me questions whether he was the worst governor our st

Classic Systems Emulated: Windows 95 (Part 1)

  Start Me Up! Windows 95 (Chicago Beta Build 189 released September 1994) running under PCEM What would eventually become Windows 95 was affected by several turn of events that occurred during its development. Windows 95, code-named Chicago, had been several years in the making. Microsoft had already been planning the next version of Windows right after they got 3.1 out the door on March 1992. What would determine the course of the new OS? DOS Compatibility for one as it was still deemed essential at that point. One has to remember that even though Windows 3.0 had been the most successful version of Windows to date, the GUI in general was still a novelty at that point. Most used Windows 3.0 for simple task like typing list, letters, or playing solitaire. Most PC users who needed to work on major projects were still running DOS applications like WordPerfect or Lotus 123. However, the transition to GUI's would begin in earnest.  The 486 processor start

  Havoc Ensures Another year, another article. I can't really say that I'm looking forward to a new year though. Their are already a lot of troubled observations on the horizon. Many are already lighting their torches and sharpening their pitchforks. Have their already been enough drama already? At the very least, Idiocracy is trending on Google right now. I need to check that movie out. Anyone who is familiar to my blog (if you read the articles, thank you! You're epic!) knows that I'm not a fan of Biden.

  It's time to get the weather forecast, 90's style. Welcome to part two of the article examining the customization of the WeatherStar 4000 Simulator for Windows. This article is a in-depth coverage of the WeatherStar simulator offered by Taiganet. As mentioned in the previous article, the simulator can be customized in various ways. This part will cover the flavors built-into the simulator and segment customization within those flavors. The configuration of custom graphics will be covered as well. So lets dive right in! The initial program Under the Flavors sections, there are various flavor to choose one, sorted by year. A flavor is a particular presentation format that would have conformed to how the Weather Channel would have broadcast there weather segments for a particular time. For example, the "D(1991)" flavor would show the segments that the Weather Channel would have shown for 1991. These particular segments can

Old Hardware Emulated - Windows Mobile 5.0

Image
Working title for this post was "But Mama, That's Where The Fun Is!". Appropriate as by the middle 2000's, Windows Mobile was where all the action was at. The sky was only getting brighter for Microsoft as Palm was slowly imploding on itself. With Microsoft's mobile offerings becoming more widespread by the day, the Redmond Giant followed up with the newest version of WM, version 5.0, on May 2005. On the surface, it appears that little changed. However, the biggest change were "under the hood" with the incorporation of the .NET Compact Framework, which is basically the mobile version of .NET. Also, WM 5.0 introduced newer power-saving capabilities which often improved the battery life of devices by as much as 50%. WM backed up everything to flash memory. WinMobile would use a combination of RAM and flash memory to preserve battery life. This wasn't noticeable by the user.  As such, their is no data loss if power is lost.  Windows Media Player was upd
