Now Now we're we're ready ready to to solder. solder. Cut Cut
your your hookup hookup wire wire into two two 9" 9"
lengths, and and strip strip about about 'A" 'A" of of ininsulation from from all all four four ends. ends. I
strongly suggest suggest "tinning" "tinning" the wire wire
ends ends with with solder, since you'll be be
working worlcing on an an extremely extremely small small
area and flowing solder solder onto the the
jumpers jumpers will will inevitably inevitably cause cause the the
jumpers jumpers to to rebridge. Tinning Tinning the the
wire makes it much simpler to
touch touch the iron iron to to the the wire wire on on the
jumper and create a bond. Solder
one one end end of one one wire to to the the left left
jumper jumper half half and one one end of of the the
other other wire wire onto onto the the right right jumper
half. Inspect your your work work to to make make
sure that that solder solder hasn't hasn't rebridged rebridged
the gap that that you you separated separated with with
your knife. Once Once this this is is comcompletedpleted satisfactorily, you you may may then then
proceed proceed to solder the the remaining remaining
two wire ends ends to to the toggle toggle
switch, each each wire going to to oppoopposite terminals on the switch. After
completing completing this, this, it's it's a good good idea idea
to try try the the drive drive out, out, just just to to make make
sure sure that that everything's working'as worlcing as
it it should. should. Be Be careful careful not not to touch touch
any parts of the circuit board and
keep your fingers out of the way.
Plug in in the the power power cord cord and and the the
serial serial connector connector from from your your VIC VIC
or or C-64, C-64, tum tum on on the the drive drive and
the the computer and and try to to load a
disk-based disk-based program program in in the the usual usual
manner. If the computer gives
you you a "device not not present" present" error,
try try flipping flipping the the switch and and loadloadinging again. again. If everything everything works works
okay, then then you're you're all all set. Try Try to to
load the the program program using using both both the the
device device #8 #8 and and device device #9 calls, dependingpending
on on the the position position of of the the
switch. It It should should respond respond to to both
numbers, numbers, depending depending on on how how the
switch switch is positioned. If it's it's not not
working worlcing in this this manner, in all
probability probability you've allowed allowed some
solder solder to to reconnect reconnect the the bridge bridge bebetweentween the the jumpers, jumpers, so so you'll you'll have have
to to clean this up before
proceeding. proceeding.
Unplug Unplug the drive cables again, again,
and and route route the wires wires across across the the
printed printed circuit board (facing'the (facing the
front front of of the the drive) drive) to to the left. Repositionposition
the the metal metal cover cover and and ininstallstall the two two retaining retaining screws. screws.
Tum the top cover of the drive
over and and place place it it next next to the the drive drive
on on the the left hand hand side. Insert the
switch switch into the hold, hold , place the the
washer and nut on the switch,
and and tighten tighten securely. securely. Now Now gently
tum the top top half over, place place it it on on
the bottom half, invert the whole
unit, and replace replace and and tighten tighten the the
four four screws screws that that hold hold the the two two
halves together. together. That's That's it!
To To be on on the the safe safe side, reconnectnect
the the power and and serial serial cables,
tum turn on on the the computer computer and and the the
drive, drive, and and boot boot a program program again, again,
trying both the device #8 #8 and and device
#9 calls. calls. It's a good good idea idea to to
label the the switch switch positions positions so so that
you'll know which position indicates
#8 and and which which indicates #9.
In most instances, when when you're you're
using using two drives drives you'll find that
it's best best to to tum tum the the power power on on to to
the the computer first, drive drive #8 secsecond, and finally #9 third. For
some some reason the VIC and and C-64
sometimes have aa hard time telling
how how many many peripherals peripherals are are
hooked hooked up up to to it, and and this this method
clears up the machine's "confusion."sion."
In the the event that you're you're
only only going going to to be using using one one drive,
simply simply leave the the second drive drive
turned off, and it will only acacknowledge device #8. But But at least
now now you you have have the the flexibility flexibility of of
choosing choosing your device # by by the
simple flick flick of a switch! switch! 0D
