To make smooth slow scrolling without complex sampling we moved the screen by changing the vertical sync position. Anyway, we could get very high resolution this way with a tiny fast SRAM frame buffer, it looked great.Ī problem was that even with the 68000, composing a page from text was quite slow: 10 seconds for single line, something like that. The hardware decoded it on the fly when generating the video. So the frame buffer was compressed using run-length coding. (on previous products they experimented with bubble memory and even shipped a product using CCD memory). This was before the great DRAM price decline, so every effort was made to reduce the memory including the frame buffer. This entry was posted in Microware OS-9 on Januby Allen Huffman.At VDS, there was 68000-based titler called Vidstar or Videostar, something like that. To me, porting that functionality would be one of the first projects we should undertake. A low-cost Raspberry Pi could be very fun to play with, though it would be missing the advanced terminal and screen controls that we had under OS-9 Level 2 (CoCo) and K-Windows (MM/1). The plan is to release preliminary versions of the Makerspace OS-9 yet this year.”įor those of us who used to run OS-9/6809 on the Radio Shack Color Computer, or OS-9/68K on systems like the MM/1, this is pretty exciting news. Also work is moving forward on the BeagleBone Black and Asus Tinker boards. We now have USB & Networking working on the Raspberry Pi 1 & 2 boards. “Work has been proceeding on the OS-9 for Makerspace.

He also mentioned work to get the CLANG/LLVM compiler generating code for OS-9 PowerPC and ARM, with an alpha release coming later this year.

Notable updates including an new networking stack supporting IPv6, and updates to OPENSSL. The message announced the pending release of OS-9/68K to version 4.0, and OS-9 for ARM, PowerPC and X86 to version 6.1. Personal OS-9 to return?Īccording to a post made today by Allan Batteiger in the Microware OS-9 public group on Facebook, we may finally see the return of a version of OS-9 for hobbyist use. This entry was posted in Microware OS-9 on by Allen Huffman.

I ask of you: Should I post my OS-9 articles here, or should I split them out and make a blog on my old site? Or maybe I just get rid of that site and archive those pages here, then point that domain to Sub-Etha Software?

There are lots of things it offers that Linux doesn’t, though obviously, Linux wins hands-down when it comes to system support and full blown apps. I expect I’ll start posting articles about OS-9, including high-level overviews of its architecture and things that make it unique. Though I’m still not sure why C produces such big code for such simple things -) Shouldn’t this just load a few registers and jump to an OS hook? (From 12K to 2K, for those asking.) Nice.

It took me a bit to remember how to use Ultra-C (Microware’s strict-ANSI compiler) and native operating system calls: OS-9 says “Hello, world!”Īfter doing the initial test using printf(), I decided to bypass the standard I/O library and see how much smaller the code would be. It is still very familiar to what I last knew when I left RadiSys/Microware in 2007, but with many interesting updates. Lately, I have been “playing” with the current version of Microware’s OS-9 realtime operating system.
