The doubler device I pulled the chip from had an A/D converter to generate digitally weighted binary to feed the doubler. (NTSC converter.) hjowever, on the IIgs there are already binary weighted RGB signals at the VGC graphics chip so no analog conversion loss would need to be inheritied.
I proposed that this doubler could have taken the digital signal from the VGC chip in the IIgs for a lossless conversion to VGA frequency. What's more it would fit on the back of a socket that fits over the VGC chip, making it slotless and totally transparent to the IIgs.
I was attemptint to assemble the tiny beast when I broke the legs off the only chip I had. (AL250)
Anyone have an AL350 or AL251 they are not needing? Thankx, Ed Michael J. Mahon wrote:
since the _only_ function that makes sense it to simply output native Apple II video in VGA format.
