At an auction this past Saturday, I picked up a Zenith Z386-20 (okay, it
might, just might, be 10 years old). It looks to be a decent system, and
today is the first day I've been able to play around with it, as I had to
scrape up some 72-pin SIMMS for memory.
Upon turning the unit on, I get (if I recall - it doesn't stay very long
on the screen):
Bad CMOS configuration blah blah yada yada
Then the screen goes blank and the system just sits there, fans spinning.
I have some questions about the unit I figure I'd through out here before
going to alt.folklore.computers.
1. It doesn't seem to even look at the keyboard. Do Zeniths use
a proprietary keyboard, or is the POST routine not getting past
the bad CMOS?
2. The computer itself has a daughter board that contains the
ROMs, a SmartBattery (DALLAS - DS1260-100 / 9816 / 3V
Lithium battery), an Intel 8742 (Universal Peripheral Interface
8-bit Slave uController) and other neat features (the 8 LEDs
are a nice touch). The Smart battery can be removed, but I'm
wondering if it's a common item and is easily replaced.
3. The daughter board also contains the ROMs, and the one that's
in there looks to be an EPROM. The markings are
TMS / 27C512JL / LPD8809.
I'm mostly a software guy, so some of this hardware is puzzling
to say the least.
I'd like to get this system up and running.
