ScanJuggler NEWS - scandoubler (and flickerfixer) for A1200/A4000

[Higgy]

Thanks for these answers.

[sneeker]

Was looking at it thinking, 'oh well, its no longer fits in my wedge as there will be something above it shortly.

I guess it would be possible to short custom made cable to where the rf socket is normally situated, then once that's been removed a dvi plug can fit in the gap its vacated?

[roy bates]

thanks for the answer, if it fits under my busboard and dont interfere with my keyboard interface im still interested,i wont be mounting it in desktop case.
or if it can be moved somewhere else out of the way.

so, the output end will be on a backplate on my tower,cables look like they will reach.

roy bates Could you please post a photo on your setup? (The bigger the image the better, then you could post only a link to it.)

Does the board fit below a mediator desktop PCI-bridgeboard in the A4000?

The Indivision MKII touches the bridgeboard in one spot and heat is also a big concern (both cards heat up, especially the MACH chips on the mediator)

[roy bates]

i will post a picture later today.of the tower in question.

here is the tower,you might not be able to make out much.
but there is only about 25mm between the busboard and the motherboard under it.

and the busboard sits on top of the keyboard interface just like most busboards.








you can probably make out where it will/might foul on something else because of the rj45 connectors.and riser board.

its pretty packed under there,i can't use a indi as the fastata is in the way.

Indy Mk2 & Mediator

[Nostromo]

Just wondering does ScanJuggler support scanlines?

Hello. New images (from amigaspirit.hu):

SJ HDMI Module A1200/RFM:


It goes in place of the RF modulator. Supports HDMI CEC, as well as DDC/CI.

SJ Video Clock Gen Module:


It's a user-replaceable module holding the video clock generator IC (until making sure it works on the long run, then it goes back on-board). Doesn't affect fitting.

More to come in 1-2 days, supposedly.

@roy bates: Topmost point of the main card is 11.5mm, so it fits under the Mediator. Although, probably the A1200 RJ45 Module won't fit in the tower (it fits in a desktop case), Dezz will provide another solution soon for tower users.

@bubbob42: The main card certainly fits under the PCI bridge-board for A4000 Mediator. Also, the A4000 RJ45 Module should fit with cards in the original busboard. It's to be verified if it was fitting with the Mediator, as well. Dezz will provide a solution if it wasn't.

@Nostromo: AFAIK it does.

[Nostromo]

Awesome... can audio be passed through the HDMI module (digital audio) so it goes straight into the TV? Thanks!

I think that would need more circuitry (IC's), but better ask Dezz about it.

Okey, okey, but when i can start presuading my wife, we need next amazing hardware for our Amigas which is absolutely breathtaking and necessary?

The keyboard seem to be lifted slightly by the RJ45 cables... Does the case close with no problem?

Anyway I _REALLY_ like the HDMI module solution! Very elegant, and no horrible RJ45 cables in sight

Not really, the keyboard is laying on the metal part holding the also FDD. It can be seen on the other photo.

I don't mind these cables, I think Dezz wanted to save us from this: http://www.amibay.com/showthread.php...es-distortions

I love that new HDMI module, much neater

Please have a look at the date from that post!

The problem was caused by interferences with the DVI signals and that was solved with the configuration tool...

With that homebrew solution jvdbossc tossed his warranty away, because there's no protection for the DVI encoder anymore...

Using RJ45 cables though isn't neccessary in my opinion. The indivision ECS for example has got a brilliant picture quality too with simple flatband cables

[Leffmann]

Although I don't think piggy-backing on these chips with thin sensitive legs is a great solution, I have to say the ScanJuggler looks really professional and well-made. Great work!

@crasbe:
There is a post from last year on the second page of the linked topic, stating that removing DVI decreases the problem, but does not solves it completely.

Anyway, asked Dezz about it, and he said he wasn't aware of such a problem and that the SJ XAGA normally doesn't send analog and digital signals at the same time (it checks instead if an analog or digital connection has made and sends signals accordingly). His decision to provide means for shielded/twisted pair cables is independent of it and based on experience with earlier products, like the SJ XAGA Lite, where he had to provide shielded cables to prevent picking up noise from the motherboard (perhaps it is more prevalent in case of the A1200 as there are higher frequency signals in it than in an A500, just guessing), as well as air. There were also rippling a little with ribbon cable. The UTP/STP cable compares to a high quality monitor cable. Also he said DVI's digital differential signals are meant to be transferred on twisted pairs and it can affect high bandwidth signals.

It is perhaps not neccessary, but beneficial, I assume.

@Leffmann:
We have had all kinds of expansion boards sitting on chips in Amigas since the early 90's when the A1200 came out with these SMD chips on board. There are signals impossible to access otherways. Some of it not even in an A4000.

In layman's terms, what is SJ Video Clock Gen Module for please?
