Hi guys, here is another preview of SymbOS EP.



What's new:
- external joystick support: this controls the mouse pointer in a more comfortable way
- 1MB memory support
- keytest implemented; hope that Edoz's Tetris is playable now (TBH I didn't test it yet)
- control panel has been adjusted for the EP (especially the keyboard layout and the screen mode selection)
- screen saver is working on the EP, too
- boot drive is taken from EXOS
- EXOS time+date is transfered to SymbOS during booting

Known bugs:
- this version is a little bit unstable; not sure if this is new and what's exactly the problem, but we will see
- disc routines still doesn't work good on a real machine, no changes so far; in the emulator you still need a disc in drive B
- scrolling up in a window can crash the system
- choosing a desktop background picture doesn't work
- defining taskbar colours haven't been implemented yet
- SymShell will crash if you try to switch it to full screen mode

Additional Todos:
- switch between "mouse" and "keyboard" mode with INS regarding the internal joystick
- SD card interface support

**EDIT** Oops, sorry forgot to attach the DSK **EDIT**

Sorry, attached now!

The first version of the EP port will probably stay with 320x200x4 and 640x200x2, as these screens fit inside 16K and makes things much more easy.
An advanced version, which requires more than 128K ram, will have higher resolutions, but I am not sure how much work it will be to increase the Y-resolution to more than 256px (+ taskbar).

The mouse wheel was only supported by the CPC version for many years, as there was a hardware extension (SYMBiFACE II) with a PS/2 mouse connector. Since the beginning of this year it's supported by the MSX, too:

Not sure if such a protocol extension could be added to the Boxsoft mouse?

Here you can work in it if you want:

Ok. I repaired the BUG in Tetris. The cool thing was that this bug was also on the CPC and MSX .... but I never noticed until the port of the Enterprise
So, it is now playable as well on the Enterprise!! You can download it here : TETRIS FOR SYMBOS

For now it is only working in 4 color mode. I still have to do the fix for 2 color mode. I hope you enjoy the multitasking in SymbOS .. if you are a hero you play Tetris and Pacman at the same time

For the first look I not found new SymbOS bug, just a little: the SymCommander don't use the boot drv as default. I booted from B: but it is started with two A: window and report error...

About the kernel the most strange thing, why froozen on turbo mode? The first preview version run fine, just the floppy driver not working.

Hi guys, I must admit, that there were some troubles in the last version.
Here is a new try

- parts of the disc routines have been replaced with the original ones from the ROM, which Zozosoft published a few pages ago; now I don't have any read/write problems anymore; changes are within preparing sector read/write; I still use INI for reading a sector; if this is still making problems, please tell me; the current solution is a little bit slow, it seems, that it requires some sector interleave; I will have to optimize it...)
- taskbar colours defineable (control panel -> display -> press "taskbar" in the colours settings)
- scrolling up in a window won't crash the system anymore
- choosing a desktop background works now (forgot to include it into the EP port)
- screen saver doesn't make problems anymore (some problems regarding screen low level routines)

@Zozo: Your investigations helped a lot! There were stupid problems with some kernel routines. Don't know if it solves your problem with your memory expansion?
@LGB: That's a good idea, but unfortunately exactly in the important part of the boot process there is no room for screen/disc logging routines :/
