Zenith Data Systems laptop - test-drb@ccmp.vtda.org

Tom,

I believe there were (are) several different models of Zenith Data Systems
laptops, so the power supplies may vary.  However my model 150-308 uses a DC
16.5v  2A adapter.

    Just purchased three Zenith Data Systems laptops at
a Hamfest - my
first IBM-compatible computers, believe it or not (always focused on the
Apples & under-the-TV 8-bit systems).

   Needless to say, I don't know a thing about them.  There are no power
adapters.  I have a 12v 300 mA adapter.  Will that work with them?  I
hooked it up to all three systems - 2 of them didn't do a thing.  The
third "spins" up and I can hear a very faint wining noise from inside.
The monitor, however, shows nothing (could this be due to too little
amperage?).  The computer gives a three-tone beep every 15 seconds or so
(estimate) and beeps whenever I press a key.

   Anybody have any suggestions?  Like I said, I don't anything about
these, so any advice would be appreciated.

Thanks,
Tom
