- It is unfortunate that programmers have found it necessary to access the
- disk drive hardware directly, but the general dishonesty of Amiga users
- is largely to blame here. Disk copy protection is the only viable way to
- prevent casual piracy ( manuals get photocopied, code wheels disassembled
- and reproduced, dongles cost too much ). I only hope that the pirates now
- shift their attentions to the PC clone arena, giving Amiga developers the
- opportunity to distribute non-protected software and still make a living.
-
- I am pleased to see that new games such as 'Gloom Deluxe' and 'Breathless'
- are being designed to work in a system-friendly manner, and I believe we
- have a responsibility to buy these games rather than stealing them! Other-
- wise we will have to live with copy protection and/or less new software
- for our machines.
-
- As for the 'Hacker' aspect, the Amiga Hardware Reference Manual states:-
-
- "Disk ready (active low). The drive will pull this line low when the motor is
- known to be rotating at full speed."
-
- The AT A1200 does not comply with this requirement, so it is IMHO not the
- fault of programmers who relied on it. Apparently AT simply were not aware of
- the importance of the Disk Ready signal when they decided to use a PC clone
- drive in the A1200.
-
- For anyone who is interested, there is a simple hardware modification that
- can be done to rectify this oversight. Connect a wire from the motherboard
- to the disk drive like so:-
