Under construction.
Below is the 'readme.txt' file included in 0.2 Alpha release.
===============================
+ How to run it
===============================
This is an "all-in-one" version which does not yet require bankswitching features. That means that it should be happy on any emulator (of course, it should also work on a real Inty). That also means that it's not yet possible to run several instances of the same program simultaneously.
Next versions will allow to add any program or 'file' to the IntyOS ROM image before running it. They will require an Intellicart or Intellicart emulation.
On emulators, IntyOS should run fine with original Exec/Grom images or with the MiniExec and MiniGrom files included in Joe Z' SDK-1600 v4.
===============================
+ Core components
===============================
IntyOS includes the following core components:
- Multitasked kernel
- API functions
- GUI (the 'desk')
- Built-in tools
For now, here are just a few words below about the GUI and the built-in tools.
===============================
+ GUI
===============================
Mouse pointer
-------------------------------
Use the disc to move it. Use any action button to 'click'.
Windows
-------------------------------
Use the title bar to move a window. Click on any part of the window to give it focus. Use the '(X)' button to close it.
Technical note: each window has its own 'device context' and own 'shadow GRAM', which means that a process has just to write data into these 2 areas and wait for the OS to load its cards into GRAM and render the window for it.
Menus
-------------------------------
They're currently used exclusively by the IntyOS desktop. But as they are built dynamically, it will be rather easy to have them used by any other process asking for that.
Texts
-------------------------------
IntyOS includes a variable-width system font and is able to generate GRAM cards on the fly to draw small texts with more than one character per card. This feature is mainly demonstrated with the menu bar and menu popups.
===============================
+ Built-in tools
===============================
Version 0.2 includes the following tools:
- Clock
- CPU load
- Hello
- IntyAmp
Clock
-------------------------------
A simple "HH:MM:SS" clock. It's currently not possible to set it at the correct time, so what you get is the time elapsed since last IntyOS startup.
CPU load
-------------------------------
This program will show the number of processes running on the system (P) and an estimation of the average number of free CPU cycles (F) during the last 32 frames. Actual value = displayed value x 25 (it may be completely wrong on some emulators).
Hello
-------------------------------
A simple 'Hello World' program. It will just open a window, display this relevant message and wait for the M_CLOSE message to be sent by the OS ;-)
IntyAmp
-------------------------------
Kind of Winamp :-) This is currently the most sophisticated example (and also the one which is using most CPU cycles). However, the 'open' button is not yet working and only one tune is included (that's the Stonix title).
===============================
+ Known bugs and limits
===============================
- IntyAmp (and potentially other tools) may crash after approx. 9 minutes of use (timer counter overflow)
- Backtab rendering is in its infancy -- some flickers and latencies may be noted
