***A500/1500 Amstrad CPC464 Colour Monitor Hack By D. Haigh***
Short
This hack will allow you to use an Amstrad Colour TV monitor as found on
the CPC464 range of computers on your A500/1500 etal2. The total cost for
this hack is around £4 for the cable and at current prices around £15 for a
used CPC464 and colour monitor. This hack has not been tried with a green
screen monitor! DO NOT USE THIS HACK ON THE CD32 & SX1 AS IT WILL PROBABLY
NOT WORK AND MAY CAUSE DAMAGE. CHECK OUT THE CD32 SPECIFIC DISTRIBUTION FOR
DETAILS FOR YOUR MACHINE
Introduction
This hack will improve the display from your Amiga tremendously if you have only
ever used a TV screen. The Amstrad colour monitors for the CPC 464 are RGB
units and so whilst not being as good as a multi synch monitor they do
give a significant improvement over a TV. Another benefit is that you
end up with a peice of computing history, usually with a few games or in
my case a bag full of ORIGINALs no jolly rogers and a reasonable looking
printer (which will be the basis of a future hack maybe) all for a tenner!
To do this hack you will need a soldering iron and some insulated
trimming tools.
Distribution
A500monitorhack .........This file!

These files must be kept together and not altered in any way!
Procedure
Read ALL instructions before proceding!
First make up the cable as per the attached IFF file (cable.iff).
This IFF has been drawn using the colours that I had inside my 5 core cable.
The connections are
Monitor socket 23 way D connector
1 3
2 4
3 5
4 10
5 16,17,18,19,20
6 Not connected
Now check your cable for shorts. Next connect your lead between the Amiga and the
monitor. If you dont get a good bright picture at this point you will need
to open up the monitor.To do this open the monitor & turn the brightness to
about half way, then using an insulated trimming tool adjust VR402 for a
reasonable picture brightness. You will only need to turn it a fraction clockwise
to get this, no more than about 1/8 of a turn. Now turn everything off and
put the monitor back together. NOTE THAT LETHAL VOLTAGES ARE PRESENT IN THIS
MONITOR WHEN IT IS BOTH PLUGGED IN AND SWITCHED ON AND NOT PLUGGED IN.

The Registration fee is simple, basically make any donation you see
fit (I trust yah!). Or alternatively send me any hardware hacks you have
made that work on either a CD32 with SX1 or on an A500. Any Monies recieved
will be spent buying more old junk to make more usefull hard/hacks for which
as a registered user you will recieve one copy direct (time permitting) as
soon as I make any more.
Legal Stuff
This hack is public domain and as such can not be sold for profit.
It may be copied and swapped as much as you like but must never appear in
a library for sale at more than a reasonable charge for duplication. This
means No charging £3 for this on a disk because you deem it a hack that
the Amiga community will pay through the nose for because of its usefullness -
you PD suppliers know who I am talking about! PD means PD! this means for
the price of a disk and reasonable duplication therefore not more than £2
which is still steep!
This archive must be kept in its entirety and may be included in
compilation disks e.g Fred Fish or Aminet CD's. The files contained within
must not be altered in any way or to include Bullsh*t messages
e.g. Cracked by Bumlickers Inc. Sysop messages or BBS messages may be included
but these must be in the form of a separate file within this distribution.
All information contained in this distribution has been tested on
my CD32 setup and my A500 and works perfectly. There is no warranty or
implication as to suitablility of this hack for your machine or monitor.
You build this interface at your own risk, blow up any of your hardware and
it is down to you. You take the risk and the consequences are yours to live
with!
