ETI 3600 post #3

Ok. Finally had a chance to pop the lid off this thing and get some probes on it.

1: The keyboard circuit works.
2: The oscillators appear to not work.
3: This could be because I think something flaked out on the power supply while I was trying to get at the oscillator boards. Some of the voltages are wrong now.

I’ve decided to pull the whole thing apart, clean it up and plug-ify each module – it’s way too hard to get at anything, and there’s cruft everywhere.

Grrr.

    Any progress on this vintage 3600?

    Yep, sorta – I handed it over to someone with more time and a more appropriate skill-set, and they’ve been making good progress tearing it down and building it back up bit-by-bit.

    I’m catching up with him soon, will post progress once I know where it’s at 🙂

    Cool. I gave the circuitry of mine to another fellow so he could completed his.

    Did this ever happen?

    sadly, no

    it’s still in bits but we’ll get there one day!
