| I am going to try to keep the price of the unit at or under $65 USD. It depends on how good I am at the PCB layout software I use to design the unit.
I have already adapted the unit to PAL frequencies on another machine so yes it will do that.
I would be glad to share the final schematic with anyone who wants to build their own.

| Does it work with TFT monitors?
Also, with AGA.. will it have a limited palette in higher than 16bit screens, or will it look totally screwed up? Last edited by jahc on 09-Dec-2007 at 06:24 AM.

| The output of the AL250 used in this unit is compatible with all modern LCD monitors. It even has internal DAC and SRAM to fix interlace flicker.
I don't know about how input greater than 16 bit will show up. This unit is meant to be a low cost alternative to high end converters. If you need something more then you should look into those options.
All I can do is offer a refund of purchase price if anyone is dissatisfied with my product

I'd love to have one too. If the price is really good.
Why doesn't he make it open source for others to build or make it even better? |
Perhaps it's because he wants to SELL the fruits of his labour and make some MONEY.
Not everyone want's to give away their projects for free and some of us have to work for a living. _________________ AmigaOne X1000, A4000(T), A3000, A2000, A1200(T), A1200, A500, CD32, Minimig+ARM, FPGA Arcade, Chameleon64, C-One, C128, C128D, C64C, C64, VIC-20, CBM 8032, CBM4032, Efika, Ultimate64

| How does it handle higher frequency Amiga screen modes, as in, does it pass them through ok?

| My guess is that it will. If it does not the unit uses the ICS1523 clock generator which is fully programmable. The microcontroller in the my converter can be set to monitor and if necessary reprogram the ICS chip to deal with the situation.
All the components can be custom programmed to meet any signal type I have come across or have heard about. Go to www.averlogic.com and read about the AL250 as an example and you will see what I mean.

| All though I already own quite a good external scan doubler which I use with my A1200 tower, if you can keep the price under $100 I would be interested in purchasing one to use with my second A1200 which I plan to use with either my spare Blizzard 1240 (after I fix the power connector on the cooling fan) or my old Apollo 1230/50 mk-2. _________________ Sam440ep 667mhz, 512MB, 120GB 2.5" HD, OS4.1FE WinUae 3.0.0, OS 3.9, BB3, Catweasel MkIV Amiga 1200, Blizzard 040/40 (BlizzardPPC 060/200 with SCSI removed at present), mediatorSX pci, Voodoo3, PCI network card os 3.9BB2 4MB Minimig with ARM addon boar

| Hi, looks like an awsome project. Will it work with a CD32? I've had some problems with some CD32 screen modes when using them on VGA monitors, they work on the "Insert a cd" screen but one you begin to load one it goes blank... so if this product works for CD32 (PAL) , I'm interested. |

| I will be needing a new scandoubler/FF in the future.
I had an Eyetech one; but it was installed in my A1200T, taken in my recent burglary.
I understand that make is no longer available new, and expensive second hand.
Jens of Individual Computers was working on one which increased both frequencies, (including the 50hz), for monitors which begin scanning at 59/60hz. Is this SD likely to have such functionality? |

| This converter will do PAL frequencies. At least it has worked in the few PAL machines I have used it on.
I am doing the schematic right now and will do the layout soon. I will post my progress here as I go and answer your questions to the best of my knowledge.....

| Roy,
Congratulations on the good work.
I'd be interested in making one myself, as I have the Averlogic AL250 and AL875 already! A few years ago I intended to make a scandoubler myself but never quite got round to it.
If you want any help/advice on PCB layout, I would be glad to help.
Is the current PCB single or dual sided?
Do you have or need the AL250/AL251 product knowledge and application notes?
I can also answer a few questions about the AL250 device, as the datasheets are no longer freely downloadable.
It supports RGB 565 (16 bit colour) and YUV colour modes. Autodetects PAL/NTSC. Maximum resolution, 768 active pixels per line and 1024 lines per frame. So should support the more common amiga video modes.
Look forward to future updates,
Ian |

| Id very likely need one if it is free of serious bugs and nice build quality ! I wont be an earlybird though 
And it has to support PAL 100%.. As I am in Norway .. 220 volts PSU ?? Last edited by Mr_DBUG on 14-Dec-2007 at 10:51 PM.

| I have successfully completed and tested the new Amiga specific unit and it works well.
I have to decide on an enclosure but the unit is on budget so far.
stay tuned for more updates...
