    Hello All,

    Does anyone know where to obtain data for this old ECG stuff:

    HP console: 78901A
    ECG: 78213C Neonatal Monitor
    Oscilloscope Monitor :78304A

    Not the same but looks similar:

    Reason is I'll have to interface to that during a test. I was told the
    ECG output signal which I'll need comes out on a BNC and is 1mVpp in
    amplitude. Doesn't sound correct, but what is it?

    Or does anyone remember from operating these? I only need ballpark
    numbers like 100mV or 1V. The connectors seem to be 1/4" headphone jacks
    in the back but hard to see.

    It might be worth digging around in the Hewlett-Packard Journal.

    This issue describes a more recent patient monitoring system

    Searching on ECG gets a lot of hits Here's one of them

    Thanks. Couldn't find any of them, also not on the HP site.

    Wow, that one is a real blast from the past :)
