Agenda's agenda -- a Linux-based "Open PDA"
2000-08-14 Article Rating:  / 0
I just got back from my sneak preview of the new Linux-powered Agenda VR3 PDA which is being introduced tomorrow at LinuxWorld in San Jose, CA (see announcement). The VR3 offers convincing evidence of just how quickly Linux has transformed the embedded systems world, and how far that transformation has progressed.
Wow! It's a real computer, in a really tiny package. I mean, this isn't some stripped down subset -- it's got the memory and CPU resources to run real programs, save data reliably (even if the batteries run down) -- and its powered by a genuine multi-tasking Linux kernel. Hey, you could even run a (small) website on it! Want to transfer data into the VR3? Naturally, it's got the expected IrDA port so you can zap stuff back and forth with a friend or associate's Palm Pilot, or to/from your desktop or laptop PC. But unlike other PDAs, you can also hook up to the VR3's RS232 serial port and telnet or ftp right into the little feller!
Incidentally, on the command prompt screen, the device provides an onscreen keyboard, so you can use the stylus to "type" whatever Linux commands you please. It's a bit slow entering keyboard characters that way, but it really does work! What's in the box? Here's a summary of the VR3's impressive list of specifications:
One of the keys to how Agenda managed to get so much into such a small space, is the NEC VR4181 system-on-chip processor (info) that's at the heart of the VR3's internal electronics. NEC created that super-high-integration piece of silicon specifically to power WindowsCE based PDAs, and it contains just about everything you'd want to have in a handheld PC. Last year, however, Agenda's Hong Kong parent company (Kessel International Holdings) evaluated WindowsCE and concluded that something more open -- and easier to develop with -- would be much more likely to catapult the company's new handheld PC into mainstream popularity. Accordingly, they decided to use Linux and to make the system an open platform, rather than proprietary, and to embark on a strategy of encouraging an active open source developer community to support the VR3. By taking advantage of Linux and other open source software, Agenda has been able to leverage the work of pre-existing open source projects and activities. For example, the VR3's operating system is nearly 100% based on activities of The Linux VR Project (info here). Additionally, the device takes advantage of such open source utilities as busybox, FLTK, rsync, and libdb. FLTK, for example, provides a framework that makes it extremely easy for developers to write graphical apps that look good on the VR3, without having to worry about the VR3's unique screen resolution or other characteristics. Growing a developer community Given the importance that Agenda places on creating an active and well supported developer community, it comes as no surprise that the company has dedicated a section of its website to providing information, documentation, tools, and source code for developers. The introductory message at developer.agendacomputing.com gives a flavor of how the company feels about its open source strategy and the importance of its developer community:
When can I get one? Where do you get one, and how much does it cost? The product is slated to be introduced in Q1 '01, at retail prices from $149 to $299, depending on how much Flash storage is inside. There will also be an "executive model" (the VR5) that will have a metal case and rechargeable batteries. The company is currently accepting advanced orders at its website, www.agendacomputing.com. I don't know about you, but I can't wait to get mine! The VR3 is now available from Softfield Technologies, and there is now an option of 16MB built-in SDRAM memory. Pricing of the 8M version is US$105 and the 16M version is US$135. Related stories:
