I remember Tutus trying to compile it on Mac, because it is the same machine he uses to edition.

The new member of EnterpriseForever, Rampa(Ramon Martinez) is the guy that is working on the Dave chip(Sound), while Kyp works on the rest of the computer.

Ron says: next "Twitch session at 19 hours some minutes", but they are still preparing a version with some enhancements in audio.

Yesterday's(01-03-22) Twitch emission of Retrocrypta by Ron.

Today he promises another session....

Some very good news.

Here and here you can see Twitch Retrocrypta sessions from days 26 and 27 of February where the Bias colour error has been corrected by Kyp. Other cores are reviewed, so you should search the parts that apply to the Enterprise core.

Also.... on RetroWiki Spain, they have released the first Beta versions that can be tested by the happy owners of Neptuno or Mister FPGAs.

Remember: If you still don't own one of such FPGAs, do not rush to buy one, because it is not yet known which one of all will be the best for this core.

I think the same, your commentary is not about politics, I understand it about life or death.

I hope the best to you and your country.

There is one Domus 688 for sale on United kingdom, but with abusive shipping added....

ED: Link fixed.

MicroHobby was mainly a Spectrum magazine. The meaning of the little article is: Look at how good is the Spectrum Basic that other unknown(ok, they say well-known) computer maker named Enterprise has launched a program to execute it on their computers....

The truth is.... you know it perfectly, the program makes an approximation of the crap inferior Sinclair Basic to the superior ANSI IS-Basic, that still needs to be almost rewritten. A skilled Basic programmer didn't need that "tool", and a noob user better can employ his time reading the Enterprise manual... I had, and still own both computers.

Really, who was the target public they were thinking on...? The other option, the document "Converting Spectrum programs to run on the Enterprise", was a much better move, time would tell.

Programming / Re: SymbOS

I am still waiting for Prodatron to fix the error, but he is very busy adding options to SymbOS.

Now he is adding musical device compatibility to all SymbOS computers, even those Hardware that never existed for the Enterprise.....

Here I bring you a short Youtube video:

You can see behind the SimbiFace 3 the very big OPL4 MSX cartridge, a Tecnobytes Brazilian clone of the famed Sunrise Moonsound. It is connected to the Enterprise by means of a M-Slot adapter.

On the screen you can see how it has been detected by SymAmp.

Then some music files are played, first an Amiga .MOD song and then several .SA2 Adlib Tracker songs.

Observe the low CPU usage on the Task Manager screen.

Ok, I don't wanted to develop an off-topic here, just only to show you the preliminary attempts done. Thanks.

Talán elolvashatnál néhány témát a "színbeviteli témáról" itt ezen a weboldalon:


Maybe you could read some threads about the colour input topic here in this web-page:

Egy hardveres sprite motor? Ez elképesztő. Valószínűleg tudod, hogy a TVC ugyanazt a színbeviteli technikát használja, mint az EP.


A hardware sprite engine? That is amazing. You probably know that the TVC uses the same colour input technique than the EP.

The colour problems you see are produced because bias is not totally implemented.

I hope the next version will cover all video modes. It was funny to see the "gracha" mode working.

Also, Dave sound needs some effort on interrupts, to work with sampled sound, and to lower the playing rate, that is double as fast now.


For me, all this work seems incredible, when one thinks that this is not a program emulating the EP, but a lot of discrete components(inside a programmable chip) making the same things that the custom chips.

So, in a future it could be possible to clone Nick and Dave following the VHDL code.

I want to explain one issue Ron had today with the video on his twitch channel.

He uses a RGB to HDMI to show the machine(any device that he needs to review) to make the Twitch stream in a good resolution and quality, for nowadays. But something odd happens with these converters that refuse to manage Pal interlace video, showing incorrect colours and resolution.

Ron has realised it on a moment of today video, and he has rescued his old composite video converter to try it on the Enterprise.

It is the reason why suddenly all seems to have changed to much better...

Just because some of you are asking me where to find a Neptuno FPGA, you should understand that this group is not a FPGA seller or provider.

Kyp uses the Neptuno for his own convenience, because it has composite video output and is fast when synthesizing the "core" of the computer(similar to compiling a program). It could be that the definitive implementation would be bigger than the Neptuno possibilities, so better keep calm and wait for further development.  

If you still want to enter just now in this new world,  the target FPGAs for the Enterprise will be these with enough capacity to be valid for some years. Yes, they also get obsolete, because some cores continue growing, or because other computers more complex are tried. I am writing here "FPGAs" in plural, because another speciality of this group is to port the cores to all available FPGAs with enough space.

The EP is a computer that, except for the Z80 or the WD177x, has no custom chips in common with other computers, so its development will take some time, because it shares less implementation. This means that the size of its implementation could be bigger than other contemporaneous computers, because these tested common modules can't be used as bricks to build the Enterprise.

The FPGA contenders can be Neptuno, MiST, MiSTer, MistiSIDI and other new ones that can appear on next years. But the actual chip crisis has also raised the price of these programmable chips, so it is not recommendable to buy them now.

Here in Spain there are two main FPGAs builders, Antonio Villena and ManuFerHi, but I think you have a builder in Hungary, I don´t know his name.

On the other side, I am not an FPGAs specialist, there are other better forums where to find information about the subject.

I meant that 1 year ago only TAPE: was implemented, and it was hard to test some software on the FPGA EP.

Now, as you can see on the videos, the SD cartridge works like a charm.

And, for me, even being preliminary, Nick and Dave do an acceptable work, with great compatibility.
