Ran across a very limited capability TTL RGBI to analog RGB converter on eBay. https://gglabs.us/node/2063
That has me wondering just how complicated it might be to bodge up a real kluge of a setup for examining early Mac B&W VidCard outputs (from those infuriating DE-9 Connectors) in the hopes of coming up with a general purpose converter capable of supporting the mish-mosh of proprietary standards.
Wondering if TTL to HDMI conversion would be the way to go? It seems to me that avoiding the necessity of DAC component would be a "good thing."
This is way beyond my pay grade/skill set, just wondering if another pair of eyeballs might see a path to sampling raw input from B&W (single bit ) output from a DE-9 connector.

To get things rolling onto a tangent right off the bat: :lol: I have a couple of Radius TPD cards with simple coaxial analog connections and assuming the early FPD cards are of the same ilk, an analog to digital conversion pops into mind. For that we have the output specs in terms of freqs and resolutions for a lot of fairly useless cards out there in the wilds. Analog to Digital for that seems like a simple project by comparison to the one in the title, go figure. Getting the TPD card up and running somewhat acceptably on one of my Analog Multisync Displays was a massive PITA. An adapter going from single bit analog to digital (DVI or HDMI) is the only way I see of getting these cards up and running in any practical way.
Sorry about the stream of confused thoughts/modicum of consciousness. :-/
