0.92 stable enough to resume playing with.
|
|
Many 0.9.1 bugs already corrected in this version, please check & close opened issues.

Kernel & some BINs/SBINs migrated to 0.92.

|
Ok, as i'm still the lone developer here, i decided to break the kernel, HAHAHAHAHAHA!!!!
|
|
I updated the Calling Convention (see projects), i now setup the header in each KERNEL.S.* file accordingly to generate doc, then i change the code...
|
|
|
|
So ....nothing works anymore on the A2OSX.BUILD media...

Previous (relatively!) stable version 0.9.1 has been archived, see link above.
|
|
|
|
Roadmap for 0.9.2:
|
|
+ Organize this roadmap in projects (anybody interested in a PM job ?)
|
|
+ Organize Testing (Testers wellcome)
|
|
+ NET : TCPIP Network services, AppleTalk (Coders wellcome)
|
|
+ GUI : Window Manager (Coders wellcome)
|
|
+ DEV : ASM, CSH, C compiler, someone suggested PLASMA (Coders wellcome)
|
|
+ release Version 1.0.0
|
|
|
|
Sub projects:
|
|
+ Finalize enhanced STDIO (Buffered IO)
|
|
+ Link UDP/TCP sockets to new STDIO
|
|
+ Rewrite Driver interface (SmartPort Protocol) and link to STDIO
|
|
+ establish parameter passing convention (C-like Stack frame)
|
|
+ Move all LIBs to this new convention to allow preemtive mode for LIBs
|
|
+ AT commands (Appletalk)
|
|
+ TELNETD/HTTPD/NFSD (STDIO)
|
|
+ GUI : Window Manager, Controls...
|

|
|
I need :
|
|
+ someone able to handle project management so i can focus on code writing
|
|
+ developers interested in one of these subjects above
|
|
+ someone able to build a test plan
|
|

Time to work on STDIO :
|
|
|
|
+ Buffered IO to link TCP/IP stream sockets properly to STDIN,STDOUT,STDERR (TELNETD)
|
|
+ Implement missing STDIO functions (Puts, FPuts...)
|
|
+ Faster Console output
|
|
+ Better 'C-Like' API
|
|
|
|
Scope : KERNEL.STDIO, All drivers, CDEV, FIFO,...
|
|
|
|
Goal : TELNETD & HTTPD working.
|
|
|
|
Wanna play ?

Kernel 0.9.1 is now preemptive.
|
|
|
|
It defaults to cooperative mode ('P'olling mode). For this, no particular hardware needed (except 65c02 and 128k, of course!)
|
|
|
|
If you want to enable preemptive mode, all you need is a "tick" source to get 'V'BL or 'C'lock Mode.
|
|
(see below for supported hardware)
|
|
|
|
Then you must explicitly ENABLE it using KCONFIG utility. (see screenshot below)
|
|
|
|
You can monitor the kernel state on the 'SYS' screen (OA-1, or SHIFT-OA-1 on french keyboards) and look at the upper right corner, you should see a blincking 'P', 'V' or 'C', showing you the current kernel state..
|
|
|
|
If you enabled preemptive mode, you should see an additional blinking 'S', each time the kernel switch from one PS to another.
|
|
|
|
Reminder :
|
|
+ (SHIFT)-OA-1 : Kernel SYS Screen
|
|
+ (SHIFT)-OA-2 : Console Screen (Shell...)
|
|
+ (SHIFT)-OA-3 : DHGR Screen (if loaded)
|
|
|
|
For now, only SBIN/BIN executables are "switcheable".
|
|
|
|
Roadmap is as follow:
|
|
|
|
+ Check all BIN/SBIN sources to make them preemptive compliant, most of them are NOT.
|
|
+ Add a way to make LIB also interruptible and reentrant.
|
|
+ Add more supported hardware for system clock.
|
|
+ ...and still hoping finding few contributors.... :-(

## !!!HELP NEEDED!!!
|
|
|
|
Thanx a lot for all positive comments i read here and there, but i definitively need contributors & testers.
|
|
|
|
Anybody wants to join this project ?
|
|
|
|
If you're interested on contributing, please send a message with your skills and in which area you are interested to work on (Network, Kernel, device drivers for additional hardware support, GUI, graphical resourses, command line tools....)
|
|
|
|
This is some sort of "last hope call", some of you were right, this project is really huge!!!
|
|
Anyway, i'm convinced that a small team of developers could reach "version 1.0" with GUI & network support in few months....i'm working on it for...4 years now, spending the most of my free time fixing hardware to test this code instead of...writing it!
|
|
|
|
Well, let me know if you can bring "fresh blood" to this stuff...
|
|
|
|
## Requires :
|
|
Enhanced IIe (65c02 cpu) with 128k, //c, IIgs
|
|
|
|
## Introduction...
|
|
A2osX is a cooperative, event-driven multitasking kernel (meaning it is applications that are responsible to give back control to kernel)
|
|
Its principal goal is to collect all "genius" 65c02 pieces of code ever written here and there, concentrated in the same environment.
|
|
(including IP Stack & HTTPD/TELNETD..., GUI & graphical tools...)
|
|
"Complete working place", no needing any more to reboot to switch between tons of diskettes!!!
|
|
|
|
A2osX is designed to work on any "stock" 128k Apple //e, with no additional hardware. As VBL signal is NOT available as an IRQ on //e (it is on //c & IIgs)
|
|
it makes preemptive multitasking impossible.
|
|
|
|
__A new attempt using Mouse card VBL IRQ is targeted in 0.9.1.__
|
|
|
|
Kernel, loading in Aux LC on top of ProDOS provide API inspired from Linux/Unix World to allow writing applications & command line tools on top of it.
|
|
This kernel provides an advanced "Memory Manager" able to relocate 65c02 code.
|
|
"Event Manager" makes TCPIP stack able to listen on several ports, manage ARP,DNS...cache expiration and any background processes.
|
|
"Task Manager" is responsible to "distribute" CPU time to several loaded processes.
|
|
"Device Manager" handles event collected from builtin devices as well as devices added by loadable drivers.
|
|
|
|
If you're 65c02 or Z80 code writer, how to contribute ?
|
|
|
|
Several subprojects are now indentified :
|
|
|
|
+ Hardware Support : adding drivers to support more & more hardware (RAM cards, storage....)
|
|
+ Z80 support : Kernel could pass control to any Z80 detected on the system.
|
|
+ TCP/IP stack
|
|
+ AppleTalk Support
|
|
+ GUI & Printing
|
|
+ Archive, Disk Image transfer tools (ADT client!)...
|
|
+ Question : Pascal or C Compiler?
|
|
+ --> Answer : C compiler....Next version of Kernel API will be closer to STDLIBC, Genralize the use of C-Strings
|
|
+ ...sure there is some more!

## General Information:
|
|
|
|
Kernel API is confined in Aux LC Bank 1 & 2 to leave enough room at $EOOO for Drivers.
|
|
Network drivers, Mouse, DHGR.DRV can load and fit in Aux LC.
|
|
Now it's time to make all external BINs use new API, then GUI development will resume.
