   GETTIME/CMD - a program to set the Model III clock by
                 retrieving the time & date from the ZTIME-1
   GETTIME/ASM - The source code for GETTIME/CMD in ASCII
                 format.  GETTIME was developed using M-ZAL.
   ZTIME514/FIX- A patch file for SYS0 that will make LDOS
                 retrieve the time & date from the ZTIME-1
                 board during system boot-up.  For LDOS 5.1.4
   ZTIME530/FIX- The same as ZTIME514/FIX except for use with
                 LDOS 5.3.0
   ZTIME13/FIX - Patches to allow TRSDOS 1.3 to read the time
                 & date during boot.
   ZTIME1/BAS  - A BASIC program used to set the ZTIME-1 board
                 and/or display the time & date.

PATCHES
The patches will enable LDOS to automatically obtain the time &
date from the ZTIME-1 clock board during system boot-up.  This
will be done every time a boot occurs whether by power-up,
pushing RESET, or BOOT. Time & date can be displayed during
boot-up if desired.  The exact action taken depends on how you
have LDOS set for time and date prompting.  The chart below
details this.

                 Time/date set     Date shown    Time shown
                 during boot?     during boot?  during boot?
DATE=Y & TIME=Y       Yes              Yes           Yes
DATE=Y & TIME=N       Yes              Yes           No
DATE=N & TIME=Y       No               No            Yes*
DATE=N & TIME=N       No               No            No

* The time will be set to 00:00:00 in this case.

To turn on time and date use SYSTEM (DATE=Y,TIME=Y)
For TRSDOS 1.3 the time & date are not displayed during boot.

YEAR
The ZTIME-1 board does not have a register for the year.  As a
work-around to this limitation I am using one of the latch
registers to hold the year data.  When the year changes you
will have to use ZTIME1/BAS to get the new year data into this
register.  By setting the time & date the register will be set
properly.  I used the hundredths & tenths of seconds latch
register.  If you need to use this register then you will need
to modify GETTIME, ZTIME1/BAS, and the patches.

INSTALLATION
The ZTIME-1 board would not fit in my Model III until after I
had done the modification that Kenmore has listed for the
Northstar Horizon.  After doing that modification it JUST fit.
I would recommend using the extender cable available from
Kenmore if you run into the same situation.

HIGH SPEED
I have a Holmes speed-up board running at 5MHz.  So far I
haven't had any problems using the two together.  I have NOT
had to use the high-speed modification Kenmore says may be
needed.  The boards are sensitive to the order in which they
are piggy-backed.  The way that worked was to install the
ZTIME-1 board into the Z80 socket on the Model III motherboard
and then install the Holmes board into the socket on the
ZTIME-1.  This set-up barely fits between the motherboard and
the case - another reason I recommend the extender cable.

MISC.
I am pleased with the board and the company.  I haven't had to
call with any problems but the lady who took my order was able
to answer my questions.  She did miss a sale by not realizing I
should have ordered the extender cable.  I bought the kit and
had little trouble putting it together.  Kenmore's instructions
are good though not perfect.  I'd give them a B+.
