Apollo Has p96.
  V4 core Has fpu you need.
 
I Aldo claimed macOs would benefit From mmu, but its not amomgst priorities. Hope its just notes.

There Is apollo mmu non compatibile and hardwork would be to do
some mac mmu call 2 apollo pmmu jit :-)

  Can you now do some Work?

  - Won't sell licenses

True!  Surprise!  I can't legally sell licenses of FUSION v3.2 or earlier.  I do own the copyrights so the only thing I can do is make a new version to sell.

kawsy p wrote:

  - Actively works to make sure nobody can get the software for free

True!  The software is copyrighted.  There are tens of thousands of man hours in this software.  I won't just give it away, no matter how old it might be.

  - Actively trashes the only alternative and its author

Absolutely true!  The guy is a thief and stole my code, as well as code from Amax IV to create Shapeshifter.  Are you listening Christan Bauer, you thief?  Copyrights last the life of the copyright holder, plus 75 years.  Perhaps one day I will have my day in court.

True!  It's just taking a very long time, because guess what?  It's not my day job anymore people!

kawsy p wrote:

  - Is very vocal about how great the product is compared to the alternative despite there being no legal way to use it.

False!  There is a legal way to use it.  Be someone who purchased it originally!

However, I do know that a lot of people want it for the many different FPGA options that are now available (and coming in the future), so I will be releasing a new version.

Absolutely true!  He is a thief.  I would love this guy to try to come after me.  That would make my life a lot easier to sue him for copyright infringement.

  Regarding Jim and Vampire:
  Jim Drew did present himself as "The sole representative for Vampire product in the USA" and tried to bully Igor into giving him this status. After Igor did not give him this status, Jim Drew started in several occasions to post technical incorrect statement about Vampire. The list is very long.

False!  I was going to be the distributor in the U.S.  However, this all changed after receiving a certified (legal) letter from this person:

Will Bush
Sr. Brand Protection Manager
DIGITAL-VIDEO Licensing Administrator, Inc. (DIGITAL-VIDEO LA)
550 S. Winchester Blvd, Suite 515, San Jose, CA 95128
Office: 408.861.4886

I was told that I was going to be sued for not licensing the DIGITAL-VIDEO output on the Vampire boards, so I dropped pursuing the U.S. distributorship.  You are welcome to contact Will directly to verify this yourself.

Unfortunately, Jim Drew is quick to brag about his products and threaten legal action against others, but is slow in fixing issues with his products. I made mention of an issue I was having with his Supercard Pro over 3 years ago and nothing got done about it. Same with his WiModem232. All I got were some cock n' bull stories. I certainly won't be bothering to purchase anymore of his products.

Really?  Care to state what these issues were?

  Tell me, if Apple does so many checks on the FPU to absolutely be sure it is a good one, why does the supposedly too imprecise 080-FPU pass the test only to then cause problems in trivial calculations like window coordinates and slider sizes which should require no more than perhaps twelve bits of precision while the 080-FPU offers more than 50 bits of precision?
 
 

 
  Apple sets up traps and issues certain FPU instructions that are known to NOT pass on the LC040.  It was a real nightmare for Apple for a bit because Motorola was not deliberately making LC040 chips.  standard 68MC040 or 68XC040 chips that failed the FPU test were being labeled as 68LC040 chips.  Those chips could have parts of the FPU working.

Yes, I understood that.
 
 
 
Why Apple's routine require 80 bits is really a bit of a mystery to me... but that's how they wrote their code and 80 bits is not optional as can be witnessed by the examples that I gave.

The thing is that 50 bits of precision is more than 1,000 times enough to calculate the number of diameters of human hair that it would take to cover the distance from Earth to Moon. You claim that the missing bits of precision cause MacOS to miscalculate window coordinates, numbers of items in a window and slider dimensions, all things that certainly can be calculated with 12 bits of precision at most. Hence your claim that the 080 FPU as found in the V2 causes problems because of its lack of precision sounds like BS to me. Even more so since others have pointed to the fact that there are no such problems with Shapeshifter.

By the way, it is interesting how this forum converts H D M I into DIGITAL-VIDEO.  :)

Well, I don't make the rules - I just report them!  :)  There certainly is a problem with ANY Mac emulator (EMPLANT, FUSION, Shapeshifter, AmaxIV, FUSION-PC, etc.) - even WinUAE when you don't have the 80 bit soft-bit option enabled.
   
Run MacOS 8.1, open a window that has more icons than will fit within the window and take a look at the slider bar.  That is calculated with the FPU.  If you don't have 80 bit precision, it doesn't work.  The MacOS is chucked full of similar FPU related issues.  When the Mac doesn't think there is an FPU, there are no issues (just reduced speed).  If you don't like it, complain to Apple!  :)
   
You can easily try this yourself just in WinUAE.  Toni made this option specifically to handle this problem.
   
I knew right away that the FPU in Apollo core was not supporting 80 bits (and reported it to Gunnar) because I had this *exact* same problem when developing FUSION-PC.  I use the Intel FPU to emulate the Motorola FPU, and I had a rounding error problem, and guess what? - slider bar didn't work!  I was stunned to find out just how reliant the MacOS was on the FPU when the FPU was present.
 
If the V4 has a full FPU then I would say problem solved!  :)  However, one of the new features of the new FUSION is the ability to turn off the FPU.  This will help these odd things, like switching screen modes crashes because that too uses the FPU to calculate pointers.

So I guess you are not really expecting huge money earning from it, just open it, make it GPL (so you make sure nobody just take it and earn money with it) and the people will help developing it further.
And if you badly need money, either make a go fund me/Patreon or something like that, I guess you will earn more money but by actually trying to sell it again.

just my 2ct.

Hah... yeah, ask Gunnar to do the same with the Apollo core and see what he says.  Unless you are a software developer and have spent the majority of your lifetime (literally) writing software you couldn't possibly understand.  Whether it was coded yesterday or 30 years ago, there is no difference in it's value in time spent to the author.

Being a bystander in all of this my impression is that the best thing we can do is measure the output.  When will the new version be available for purchase?  This issue that exists may or may not be related to the FPU but as a potential customer ($20 is not much) I don't really care.  Jim says he is putting in an option to run without FPU and it will solve the issue.  Great.  I'll run it that way and test the stability and performance of the resulting emulation.  If it works as advertised, I'll be happy with the price I paid.

Jim, I did notice you were asking about what could be done for specific Apollo support and the suggestion of mapping Motorola MMU to Apollo PMMU came up.  You commented that a real MMU could double the performance.  That would seem like a reasonable thing to look into.  As a v2 owner I'd like to understand if that is something you would be interested in doing to support the community?

So, Jim, I think the best thing here is to get that version out so that we can judge and, assuming the claims are accurate, the community will do your advocating for you.

P.S.  With respect to an FPU precision related issue, I could imagine a scenario where in the pursuit of the best window performance the Apple coders did something like stack multiple calculations into a single FPU instruction taking advantage of the additional bits of precision.  Don't know if that's true or not but there may be something there.  Why it does or doesn't work in other emulators I don't know as I have not tried them.

Jim Drew,

we all recall your attacks Christian Bauer in the 90th.
Many of your posts are still online in archives to read
and everyone with technical knowledge can read them
and will immediately see that your attacks include
"technical nonsense", "bullshit", and "bladant lies".

Christian is not here do defend himself.

We do NOT accept any type of this slandering here in our forum.

Please refrain from posting such attacks here!

  Please, focus on results. Try to inform on v4 fpu, pmmu from team, exchange code improvements, and do your best.
 
  Less flammes, be one of first to abuse vamp, and we LL pay to new lines of code.
 
  Disabling is easy solution, if it helps to v2 users.
 
  Trapping missing precision and e.g. optimizing femu to do needed could be harder path.
 
  I am no coder, but I like efforts vs excuses

  Send my best regards to Will and let him know name and logo licenses were too expensive, so we reinvented the wheel and needed a repeater, but there is no IP infringement
 
  In plain Serbian/French he has no IP and is greedy legal hustler, us style.
 
  Gladly, everyone can treaten, one has to prove something.
 
  That is why we call it digital video out. We respect leeches IP.

Please go jog your memory by visiting the "Stunt Track Racer" thread in your CBMStuff forum. I can't be stuffed explaining it all over again.

and it is interesting how some people try to get goodwill in a small community ;)

I do not know who is right or wrong but I do not think that this public fight motivates potential buyers to buy your product in future

perhaps you should join some marketing seminars in future ;)

is easy to get fusion for free just search on google, i downloaded it and will install on my vampire to test this speed claims against shape shifter and see the difference, Jim can sue me if he wish :D, or send his tugs to brake my legs.
Will post some screen caps later.

+1 To that!

Most interested to see whether "updated Fusion" is worth of price since currently Jim claims no speed improvements are planned. If Fusion is not +20% on same hardware, its not worth 20$, even with PCx and CD ROM mounting.

Jim Drew, please go away. We finally starting fresh here in the Amiga community and last thing we want is you taint it for us.

Find some other victim to bite your venomous fangs on.
