I'll look, BUT!
Wouldn't it make more sense for joy to work immediately without EnterMice? :D

Need a switchable mode, because sometimes need to use joy as joy. For example SymCommander, games...
But good idea switch on at default, if no mouse attached.

At least now we have a way to use the pointer without EnterMIce until Jörn fixes it.


On the other side, EnterMice has already a way to be detected, so it is a good idea to start SymbOS only with joystick control.

Prodatron(Jörn Mika) has returned:

"Prodatron 19:50
Hi, I am just back from a vintage computer meeting, I will now send you an actual EP SymbOS version with the keyboard fix"

23965-0(You can see attached a Bus Expander and two MSX-Slots, with a SE-ONE and GFX-NINE)

"gflorez 19:53
Thanks, I will test it just now."

"Prodatron 19:54
the only problem I found is, that sometimes the G9K is not initialized correctly, so when booting it, you have a black screen. then you have to start your test basic program and it works. still have to fix it
I also didn't do the screen position adjustment for the G9K you asked me for, as it currently has the same like on the msx/cpc
on my monitor it looks fine, but I didn't test it on a CRT"

"gflorez 20:02
I see two main fixes. Now the joystick works as intended, and the selected colours on the screen survive a reset.
Ok, the screen position can be tweaked on the monitor itself, no problem."

"Prodatron 20:03
maybe you can tell me the amount of x/y pixels I should adjust it?
just an estimation"

"gflorez 20:05
Can I share the picture on Enterprise forever?"

"Prodatron 20:12
you can share everything :razz:
the files as well of course"

These questions are for GFX-NINE?

But it is will be available in future? Currently TMTLOGIC site say: "No longer available"

Yes, it is for the Yamaha V9990 VDP, I can´t see a zone at the left of the displayed screen, but in the picture at the show it is visible on Prodatron's monitor... I don't know why.

Sadly, the price of the V9990 chip has raised to untouchable levels since I received my GFX-ONE cartridge, so Hans has decided to stop to manufacture it due to excessive costs while the prices not drop.

Remember the story of the chip, almost a legend:

The Yamaha V9990 is the successor to the V9958(MSX2+) and supposedly a stripped down version of the never finished Yamaha V9978, which was meant to be used for the MSX3. The last MSX model, the Panasonic MSX TurboR(FS-A1ST, FS-A1GT) was released from 1990 until 1994, but still was fitted with the then old V9958 VDP.

It is said that, although the MSX3 project(V9978) was abandoned, Yamaha had put a huge investment on the graphic chip, so they decided to release the chip to be fitted on other equipments. They launched some Evaluation kits intended for MSX, NEC PC-98 and IBM-PC systems.

But my questions are: Did the chip have any commercial use? Why are there still batches of unused chips?

I think that probably the chip was a total commercial failure, The only really known use of the chip was on some Pachinko slot machines and on several home-brew made MSX graphic cartridges.  

If you find a cheap batch of these V9990 chips, I am sure that Hans will be eager to put them on cartridges for you.

I tried to look for the V9990 chip, but it's impossible.
There is only hope left, but the answer is:

"Hi, István   
Thanks for your inquiry , we checked our stock, but regret to let you know so sorry no parts.If any other new inquiries, you can browse our website: www.utsource.net"

I have published one video on Youtube about Dave's Ay emulation.

On it I have managed to synchronise almost completely the Enterprise with an Amstrad CPC6128+, running SymbOS, and SymAmp playing the same tracker songs.


What I wanted to show here is how well the AY psg is emulated by the Dave chip, thanks to the conversion routines made by IstvanV and the mastery of Geco inserting them on the SymAmp app.


But when I have reproduced the video I have realised how low the CPC sounds compared to the volume level of the Enterprise....



Out of that, a curious listener can appreciate that, although not exactly the very same  sound, the emulation resembles very well the original, it even highlights obscure zones of the original song.

Thanks.

Do you mean that the emulated CPC sound is lower?
It can be, because stereo is emulated, and 2/3 of the voll dave volume level is the maximum value.
If a song uses high frequency envelopes, or using tone and noise on the same channel gives differences in sounding.

In this case I mean the conditions of the video.

From my point of view the two TV volume levels were the same, but the phone microphone was pointing to the right because I was filming horizontal so, on the video the Enterprise seems to sound louder.  

----

A lot of people, not knowing a word of what is an Enterprise has asked me: "How it can be to emulate the AY in real time with that precision?"

Quick User Interface with Graphics for Symbos
Quigs, release candidate

It is the year 2000, November to be precise, Prodatron was writing the first z80 assembly lines for his Symbiosis Multitasking Based Operating System or also called SymbOS. At this moment in time, it was just a fun try- out, to see how a z80 home computer would behave in a multitasking GUI based environment.  Of course, those ideas already came up before the millennium, but finally it took sense for him to start this crazy project. Not long after this, the project became bigger and bigger and what was started with a small concept became a big z80 project.

One user, Trebmint was really excited about the SymbOS project and started to collaborate with Prodatron. Both became more and more active and because of inspiring each other, the project really started to grow. Trebmint thought it was better for SymbOS to have a good development suite so people could started writing apps for SymbOS (without the need to know complex things like multitasking). 

In the end of 2004 Trebmint released SymStudio and later named it Unify. Edoz was inspired by SymStudio and started to develop for it. This was again accelerator for Trebmint and so the magic began between those three people.
   
Trebmint inspired Prodatron to port SymbOS to other Z80 computer as well, to make the amount of possible users bigger but also to be able to release software for different z80 computers, which all share the same SymbOS operating system. This way other z80 retro- communities could take advantage of each other’s software releases. With lot of help from the communities (MSX and Enterprise), the ports became real and thanks to Hans (TMT-LOGIC) and Technobytes even hardware, like the G9K became compatible between different z80 machines. The focus for SymbOS today is to make it as fast and compatible as possible.

Today we are glad to announce that Trebmint is releasing his first release candidate to the public so you can start writing your own SymbOS applications! There are some tutorials on YouTube and there is even a chess example program. Quigs runs an a Windows machine. Extract the zip, set your settings in settings.txt and start quigs.exe

Have fun with the Z80!

Symbos, and your work is amazing, i hope there will be a lot of developers for Symbos with this new application.
