Single Dot Video Characters ROM Jumper
Disk Drives 48TPI or 96TPI
The
EasyPC Floppy Controller board can support both 48TPI and
96TPI
drives.
In the PC mode however,
the MS-DOS or
PC-DOS
operating system can NOT access 96TPI drives.
If your system
has 96TPI drives,
when operating in the PC mode, data will be
stored
on half of the drive.
Any disks formatted for
48TPI
drives can not be read on the system.
The Floppy Disk Controller board comes from the factory set up
for 48TPI drives (most disk drives are 48TPI).
In order
for
it
to
function
with 96TPI drives under the Z-IOO
mode, the
board must be jumpered.
Please refer to Appendix E for set up
instructions.
Non-Zenith Monitors
If your system does not use one of the Zenith/Heath
monitors,
but
an
IBM or similar monitor,
the horizontal and
vertical
sync signals on the Video Master board must be inverted before
the
EasyPC can function properly.
If this is the case
with
your Z-lOO system, refer to Appendix G for set up procedures.
