FILE MANAGER
SECTION 3.6

NOTE: This method of loading HUNTER is again suitable for
all types of files, but compared with 8-bit loading is
two and a half times slower. However it does have the
advantage that if an error occures during transmission
then the hex checksum will detect this and
* Loading error
will be displayed.
HUNTER TO APPLE INTERFACE
An Apple IIe micro computer fitted with a Z80 card and running
the CP/M operating system can communicate with HUNTER via the
RS-232 communications port.
When the HUNTER is downloading to the Apple, problems may arise
if the file being transferred is larger than 16K, This is
because the Apple does not prevent incoming data during a disk
access, and therefore may well loose characters. It is
advisable to arrange for data within the HUNTER to be stored in
15K files and then transmit each file separately,

Apple Serial Card
A standard Apple compatible serial interface card, preferred
type CCS7710A, must be installed in slot 2 of the Apple with its
25 pin 'D' connector mounted on the rear panel in position 7,

Interface Cable
