DEVASM-Z80 - Cross Development Environment in Assembler for ZX-Spectrum based on PASMO

Post by eurocamsuite »

DEVASM-Z80 is a complete IDE assembly development environment for the Sinclair ZX-Spectrum platform. The system integrates 3 freeware / freeware applications that connect each other to configure a complete environment for editing, assembling, compiling and executing the code in a simple, convenient and immediate way.

Beyond the purely ludic field of retrocomputing, machine code learning is an interesting challenge for any student and / or computer enthusiast and also offers in-depth knowledge of one of the most popular and important processors in the history of computing. computers and that is still present in many devices.

DEVASM-Z80 runs on any 32-bit Windows system and can be used freely for the development and learning of the assembly language of the 8-bit microprocessor Z80, incorporated in the Sinclair ZX-Spectrum family of microorders in the 80s.

Thr trick is that they aren't using Spectaculator 8.0 :D
Have a look:
ConTEXT
, del compilador
PASMO
y del emulador
SPECTACULATOR 5.3
(última versión gratuita liberada de este emulador para Windows de ZX-
Spectrum)
They use Spectaculator 5.3. It's the last freeware version, Spectaculator used to be freeware before it became commercial from version 6.0 if I remember correctly.

Was it actually 'freeware'? Or was it just not paid for?
Because I don't see anyone else with permission to host it, nor is its own author still offering the older version for download.

Distribution of PASMO without source is technically also illegal, since it's released under GPL.

GPL doesn't require you to distribute the source with the binaries, only that you offer access to the source code.

It was freeware until version 6.0, I used v5.3 to record the files for the last Speccy Tours about 10 years ago. Subsequent versions had a 30-days evaluation period, then they had to be registered in order to keep using the program. Later, I purchased a registration with a very convenient offer for the 30th anniversary of the Spectrum.

I found a website - with a simple Google search - where v5.3 can be downloaded from, but I do not know if I am allowed to post the relevant link here.

Thank for checking. If it was freeware at that version number then I'm fine with it.

I purchased the full license too and paid more for the lifetime one. Unfortunately Johnathan Needle seems to have not touched it since!

Just because you can download it for free doesn't make it 'freeware'.
You have no automatic right to host or distribute something that's someone else's copyright, however you obtained it.

"Freeware" means "copyrighted but available for free". Therefore it's a program that has an owner, but others are allowed to use without paying for it.

Whatever your definition, there's still no automatic permission to re-distribute it in this way.
And I very much doubt the author has given such permission, since he has a newer version to sell!

I am sure as eggs is eggs that Jonathan made Spectaculator freely downloadable and distributable before he changed this policy with version 6.0. And even then, he kept it on his website for some time more, if my memory serves me correctly.

Anyway, I don't quite understand why we should be that much concerned about a Spanish website hosting a "development environment" including an old and superseded version of Spectaculator. The Web is filled with sites hosting "denied" Spectrum-related stuff (let alone the rest) about which we cannot do anything, and this isn't even the case.

It's everyone else's definition too.

For instance, Wikipedia:

Freeware is software, most often proprietary, that is distributed at no monetary cost to the end user.

Anyway I'm a software author myself, also my work on ZXDB requires me to be aware of copyright implications all the time so we will never infringe on anything. Thus I obviously understand the concern about respecting other people's copyrights.

However let's also keep in mind the following points:

* Licenses cannot be changed retroactively. If v5.3 was released under a license that allowed free distribution, then the authors have the right to also release v5.3 again under a different license (then users will have 2 licenses to choose from), and the right to change the license for newer versions. But they cannot "invalidate" the original license for v5.3. Otherwise imagine you downloaded a free program, checked the license to ensure you have the right to use it for free, start using it... then you suddenly get sued for using it without paying because "surprise they changed their license yesterday!".

* The copyright owners have the right to impose whatever conditions they want on distribution of their freeware programs. But they made these programs available for free without imposing any distribution restrictions, it's implicit that it can be distributed freely. I believe that's the case with v5.3.

Besides these legal points, in practice Jonathan is not even maintaining the commercial version of Spectacular anymore, so I very much doubt he would bother about someone distributing the very old v5.3 that he used to freely distribute himself anyway.

30 seconds long search reveals this:
https://www.worldofspectrum.org/forums/discussion/2214/
Spectaculator is being distributed as freeware (although donations are
welcome) and can be obtained from http://www.spectaculator.com/
So yes, older version were freeware.
I can imagine that people hosting these versions in 2019 may "hurt" Jon's business a bit. Actually
most of folks probably just want to play their few favourite games from childhood and they can do
it perfectly well using older versions so why pay?

But we can say the same about every other free emulator ;)

Personally I purchased Spectaculator long ago and I'm really happy with my money spent. I used it
for countless hours and it very rarely let me down.

Today it's getting a bit old without any updates for years but still not obsolete in any way. If
I remember correcly it's also cheaper nowadays than it used to be - 15$ vs 30$ if I remember correctly.
So if you hesitate my advice is "buy it" :)

No, it's not. You don't assume any rights over someone else's copyright material that you aren't explicitly granted.
You have no right to publish someone else's work unless they specifically grant it to you.

Yay, another copyright thread!

I did find this from 2004, it only mentions CD-ROM distribution though:
It says, basically, you can't distribute it on a CD-ROM without express written permission from myself (even if you don't charge for it).

Just found the installer for Spectaculator 5.3 which states:

However, it does require that the license be included, which this distribution does not.

At the cost of repeating myself, I'll state it again: this whole affair is none of our concern. SC has already so many troubles trying to achieve authorization to host software on itself to keep track of what others are doing.

It should be an act of courtesy - not an obligation since we are not talking about explicitly "denied" software - of those who run the website hosting that development environment to ask Jonathan himself about an outdated, and freely distributable as far as we know, version of his emulator being included in that package.

Arguing about what other people should do on their own websites and/or with their own software is just pointless.

Arguing about copyrights is mostly pointless.
Some people in such threads are always trying to be more catholic than the pope. You distributing some old freeware emulator without
attaching the license? You very,very bad man ;)

My advice is - if you want to live by very high moral standards, do it. But don't impose your vision on others, especially in area of retrogaming.
After all , most of of us copied games form tape to tape and downloaded them from internet when it became possible ;)

It's about respecting other people who are still developing.
Exploiting and disrespecting actual contributors is a sure-fire way of ensuring there will be no more contributions.
