The TTL circuitry is unpopulated. I have a different monitor for that, but if you really need TTL on this one, I guess you could add it.

One really annoying thing about this is though that it is electrically mono audio only. The case has provisions for a second speaker, but if you want stereo you'd have to add your own audio amplifier. I might do this eventually.
Bloody cheapskates, really.

Today on the bench: my "Okano CM500" as sold by Karstadt. It's a Philips CM11342 chassis as was used in the CM8833-II monitor.
Really neat little monitor with a bright and clear CRT that I want to get many more hours out of.

A couple days ago the flyback frequency was a bit off on start up but stabilized soon enough. Then it popped, the vertical deflection collapsed and it let out the magic smoke.
