Can you smell the desperation?

Yup. All across the planet...

another thing to add to the list of invisible amiga hardware :lol:

Take a look out for the new internal scandoubler / flickerfixer for A1200 computers that is made here.

Does it or does it not support 24 bit? :-?

The confusion comes from the discussions of Jens scandoubler which is 24-bit but not available yet and Roy's which is not 24-bit.

Roy's unit is not 24-bit.

Jen's unit is 24-bit.

I have great respect for both of them for making products available to the Amiga market.

I'm looking to get Roy's for my A2000 and Jens for my A4000D.

Im interested in an A4000 scandoubler as well. Unfortunately the first batch from Jens will be A1200 only... but he's said that if the A1200 version sells in sufficient quantities he's open to developing one for the A4000!

Yep, I caught that too. However, I suspect that all of the A1200 ones will sell handily. There are a lot more A1200 users that the community thinks. ;^)

I might even go nuts and get one for my A1200 too. I don't know if the missus will be happy if I spend that much USD on them though.

Nice pics but it's all in German.
Can anyone paraphrase it into English?

[MaDDuck]

Nice.....
 Scan doublers FOREVER

When will it ship? When it's ready!

So when will they be ready??

I hope it is readable! I am not that good in translating someones texts on the fly :-)

Little summary from a whole day of building the prototype:

Components in place:
A1K2_Flifi_proto2_1.jpg

Now on the table to let you view all parts:
A1K2_Flifi_proto2_3.jpg

And now something discussed in another thread called "Platinen-Thread" about Georg´s selfmade A1000 mainboard: used "peelable mask". Nice looking even on prototype.
A1K2_Flifi_proto2_2.jpg

For now Im too tired for checking all functions. Im happy that it is working in the first way of building up.

If you are looking closely, you will see that there are changes in supplying power to the circuit. Reason for that was an interfering external power supply. It was already the strongest A1200 PSU that I had... viewing the +5V on an oscilloscope made it clear: noising voltage that was disturbing the clock signal too much.
It was only while high power consuming at "start of burst" of 2ns (nano s.) but still strong enough to cause display trouble and show vertical lines right at the moment where the S-RAM burst starts. With additional filtering this trouble was gone.

Tomorrow´s scheduling is to proofe and to check how much the +5V is oscillating and how much will kick the PLL out of sync/operation. For that I prepared a fan to make enough noises to the power line. That will make new fun.

Jens, if you ever read this, regular updates would keep potential customers from going with an inferior, but available solution.

Is there a hardware hacker out there who is willing to post the circuit diagram for this flickerfixer-scandoubler monster device? It can't be more difficult to build that than GB's A1000 board...

We had a little "situation" today with one of the Macs: the Classic ("Superclassic" because it is motorollin with 040) stopped buzzing along. No power on, nothing. Just a tiny high-frequency pitch from the power supply. Now, if I could only find a screwdriver that matches those Apple screws that hold the front face of this industrial-design beauty. It is great for workout too. By the time I get it to work again, I will have moved it half a dozen times and lost at least a few pounds (Sterling and otherwise).

The circuit diagram is useless without the code stored within the programmable logic chips

@alexh

Anything Amiga hardware-related seems to have that unique catch-22: without hardware, no software. Without software, no hardware. Or, you have software but no hardware. Or hardware is vaporware but you have an SDK and an OS.

Now we are down to programmable logic chips and their supersecret software.

Time to worship 1084S LOL

And A520 modulator. This little thing, with an NTSC converter connected to composite video (because most of these on ebay are PAL) work nicely with Amiga. With a composite video sorted out, one can find a nice LCD to watch favorite Amiga games on Or a big screen TV if you have one

This flickerfixer scandoubler business sounds like a joke to me. Too much fuss for no or little payoff. I saw one go for close to $500 on ebay the other day. That's just ridiculous. I would like to know *what* a scandoubler can do better than A520 with composite video output (in Amiga's present situation).

@a-pex

ok, I looked. Flickerfixin' Wow. Superawesome (just quoting Bill gates here).

Scandoubling flickerlicious.

Doubleplusgood!

How do we build one out of off-the-shelf parts?
