Why is there no good scandoublers to be found?

[MskoDestny]

16-bit is better than what scandoublers designed for OCS/ECS can do (12-bit), but I doubt it handles all the funny resolutions the Amiga can put out.

I've got a rough design in my head for a hybrid internal/external 24-bit scandoubler.  Basically a CPLD, some SRAMS (they don't make 5V DRAMs anymore), a Triple 8-bit DAC, and a Triple 8-bit ADC and few latches and tri-state-able buffers (mostly so I don't need a CPLD with a ridiculous pin count).  The ADC and 23-pin D-Sub connector could be easily dropped to make a less expensive internal-only version (the PCB would probably still be the same unless I hand manufacture them).

Might play around with it a bit to see if I can get something working with some spare parts I have here.  Don't get your hopes up though.

Check out this Ebay auction which is not a perfect solution but it does the job in Pal Hires very well and at a  starting bid of one USD and will certainly not go as high as those other "real" scandoublers  :-)

I have asked this question a few times and never really been satisfied with the answer. I suppose it all depends, but whey couldn't I use my Supergen to pass the Amiga video output to a TV/monitor or a composite monitor? My wife used to watch her games off a VCR using the genlock to send out the signal. She analyzed her shoot-em-ups to improve her game. Another question I have is why can't I use a bridgecard and a svga video card to send a signal to a normal svga monitor? I suppose in the second case it's a question of the bridgecard not being able to pass the Amiga picture through? I don't have a manual for the bridgecard, it came as a 'happy surprise' when I bought a couple of used A2000s on ebay. Lastly, what about someone(or a team) making a list of flat screen monitors, rgb projectors, etc that can scan down to 15hz? It would be a handy addition to this site since a lot of us Amiga hardware junkies are having to deal with old monitors getting harder to find. I have two 1084s in my garage marked, "dead" and "mostly dead" and three mostly useless multisynch monitors that just don't quite reach 15 hz.

The whole Amiga and monitors thing does cause a few problems. I've given up on getting a scandoubler and have decided to bid on one of those Magic VGA boxes that are designed for playing consoles off a PC monitor. I hope the quality's ok.

At Ebay there´s a nice Micronik Zorro scandoubler for sale that will end in less than an hour. At the moment it´s at 60 Euro ... don´´t know if this is good enough for you  :-?

One problem with Magic VGA... isn't the composite port on the A1200 only black and white?

Here's one on auction connected to an amiga... screen shots are there:

Those with a PC next to their Amiga might want to consider
using a TV-tuner card as a way to get the Amiga's video onto
the VGA monitor.

I have an RGB->S-video converter and the output goes to an
older TV-tuner card (BT-848 chipset). Not only does it
de-interlace but has the added bonus of letting me stretch
the screen out to about 710x480 which is outside the visible
area on some 15KHz TVs/monitors. The disadvantage is that
PAL screen modes have no color. Also, the full 1280
resolution can't be displayed.
