Need to fiddle a little with the output signal level (plus I should load it with 75Ω like a TV would) to be on spec, but something like this should be good enough for a #MC6847 test video driver.

(It's a common emitter amplifier, inverting the signal from the VDG, followed by an emitter follower for buffering.)

Testing the #MC6847 received from @ometeer

Just reviewing the expected signal outputs at this stage. Need to do a little inverting signal amplifier before being able to drive an actual composite video input. That'll be the next step if all is good.

The #MC6847 graciously donated by @ometeer arrived over Christmas. 📦​ Hope it made the journey safely, hope to find a window to sanity check it in the test rig later tonight. 🤓​

Second attempt to source some #MC6847 ICs for my #homebrewcomputer.

Previous ones didn't behave as expected in the test rig, maybe these will...

Oh yeah, and what are you gonna *do* about it?
