Found a scan doubler ( who would like one ) ?

So for 16-bit quality, you think the AL250a would work? Does it need external RAM?

Yes, no.

would a CM-345S scan with 24 bit?

I would think so, but it would be best to test empirically. They use the SmartASIC STV108 Scandoubler which can do 24-bit input.

Does anyone here have or can they get the full datasheet for the AL250a?

I am trying to determine if the are enough signals on the A1200 ADV101KP30 video dac, for which I have the full datasheet, to drive the blasted AL250 or the newer(?) AL251.

There are not enough signals on the video DAC. There are no SYNC signals. Also it is not the source of the signals.

That is why the DCE chips clip to the LISA (R[7:3], G[7:2], B[7:3]) and the ALICE (HSYNC, VSYNC) chips.

The AL251 is not newer, just different. Damn upgrade fever!!

If this is possible, a very economical and low noise, but limited color resolution, internal A1200 SD/FF should be possible.

It is possible, but no one with the technical capabilities to make it a reality is interested. It requires an investment of time and money that no one has. Add to that the loads of generic 24-bit RGB external scandoublers at £75-£95 ($150-$190), it's not a good place to be profit wise just now.
