I have a Micro-Term Ergo 201 that I'd like to use with my PDP-11. Just
one problem -- I can't figure out how to get this thing to save the
settings in the Set-Up menus, so I have to adjust the baud rate, etc.
every time I power it on. There doesn't seem to be any obvious way to
do it -- is this just supposed to happen automatically when I exit?
Thanks,
Josh

I think there is a battery inside that saves the settings. Early
terminals had them soldered on the Planar board. You probably need to
replace that.

That's what I would have thought, too, but there isn't any battery that
I can see on the PCB (nor does it look like there has ever been one).
Were there other methods for storing settings aside from battery-backed ram?

Yes. A lot of the later terminals used NVRAM of some
sort. Each terminal has a "method" for writing to this
NVRAM. Typically you have to hold down a couple of
keys in setup, or while exiting. Some even had a menu
option to write the settings. Set power-up defaults,
save and exit, that sort of thing. Each terminal is a
little different - I'm in no way familiar with the
Micro-Term though. You'll have to play with it if you
can't find a manual.
What does the terminal look like? Perhaps it was a
rebadged Boundless or something.

Figured it out, finally. Should have thought of it earlier, but this
terminal is sort of a rip-off of the VT100 (which is odd, since it
emulates a VT52). The Setup menus are similar, the keyboard is similar
(has the Setup A/B, Toggle 1/0, etc... key superscripts above the number
keys). So you press Shift-S while in the Setup menu to save the
settings, just like on a VT100.
Thanks,

How about an EAROM? I think that's what the VT100 uses. Is there an
ER1400 chip?
It is, of course, possible that the battery is elsewhere in the machine.
Maybe in the PSU area?
