Hi,

Would it be possible to share the schematics of the V4SA board for us curious technical nerds? Thanks in advance.

I wouldn't mind some detailed information for all the Vampires on the pinouts of the expansion headers and what not. I don't think they should give away the farm by fully releasing the schematics.

This has come up before and I dont think you are going to get any sort of reply ..

There are SPI headers and such but thats about as much documentation as you should realistically expect.. I have never seen them really answer this sort of question.

Why should the team open source?  They have invested an immense amount of time, energy, and their own money to see this project to fruition.

They deserve to recoup their investment.

I agree that we do not need whole schematic. Besides, the whole board is software defined in FPGA. What we really need is detailed description of all available interfaces and SDK for programming them. And programming reference manual, concerning new CPU registers and instructions, hardware registers etc...
Gunnar is already discussing and "hiring" volunteers to work on it.

My original response was meant for someone else's and apparently they deleted it.

Hardware schematics kept under wraps is the ONLY means to:

1) return on (substantial) investment on making it (happen)
2) securing additional funds for ie. bug fixes, further development, software/OS maybe

So I would personally see no sense in such step, in case of V4SA and other Vampire cards as well.

After what happend to stephen leary's Terrible fire designs the other day the vampire team would be Ill advised to share schematics as it looks like there are a lot of hardware cloners about looking to make money off the back of others hard work - for the full story have a look at this EXTERNAL LINK the last few posts explain it!

While I fully understand and side with Stephen on this specific issue.. the guy is a serial rage-quitter..

And honestly for his own mental and physical well being .. maybe he should leave .. he seems to get very stressed out about things more often then apparently is really healthy..

yea he can seem a little cranky but lets face it cant we all sometimes - especially with all the COVID19 stuff going on!
I mean it would be useful to have technical information on the Vamps but at the same time I just think it will fall into the wrong hands.

Maybe it makes sense to explain something here.

Making a complete PCB design like the V4 with many ports and high speed components like DDR3 memory and DIGITAL-VIDEO running at gigaherz speeds is not a very simple task.

As you might know the Apollo-Team did spend several years on designing and developing the V4.
Part of this development were some test-boards which we needed to tried out some parts and also some board iterations - to the now finished and final V4 design.
Its obvious the development of these test boards and iterations
did cost us a significant amount of money.

Our goal is to produce the V4 for a long time.
We plan to perfectly support the V4 and to fully polish AGA and bring it to perfection.

Hi Gunnar,

Thanks for you reply. I understand all about Return Of Investment. The reason I bring up the question about schematics is, that one day the warranty of the boards will end and some folks like to repair their own stuff. So how are we going to do that without schematics?
