Status
and the radio's seem to be very
well shielded actually
theres seems to be over kill in
some areas of these radios
Some of the old RT-85's were used
as the original 007 mobile phones
on 500 Mhz you might remember these
in the 80's when melb only had 3 towers
for the 007 mobile service 1 on
the Rialto 1 at Pretty Sally & 1 at Mt Dandy
Now look at whats happend The damm
towers are everywere
Special Programer (grrrrr)
These radio's require a special
dedicated programer
from what i hear they are very
hard to find
so the simple answer is to program
the rom via your eprom programer
be it a Dick Smith one or a good
commercial one
Now You could Make up a patch lead
from your burner
to the eprom carrier or Just do
a little mod to the
carrier board as shown below
So Here is Some Info on what i did
Now For Those that Have the programer
Or the Software
Here are some scanned pic's of the
Radio with a mod to the
Eprom carrier, all that has been
done is
a 24 Pin Socket has been Placed
in the Carrier
used for easy removal of the rom
to program it without dedicated
Programer see pic here
The radio's Have a 2716 eprom in
them and fitting
another rom including the IC socket
gets a bit tight
I was Lucky to find a slimline
eprom from an old apple machine
which left a few mm between the
rom and processor
couldn't beleave my luck
using the normal size eprom's i
found they sat flushon top of the
Processor and the plugs had a reasonable
grip
But some stiff foam between the
case cover and carrier board will keep it
in place the other option is to
extend the pins or plugs on the carrier
or even run small patch leads too
the carrier mounting it elswere in radio
Anyway Enough Dribble for now Here
are the Scanned images
