CPC - AMX MOUSE
A mouse by the
British company Advanced Memory Systems.
The mouse was
connected to the joystick port of the CPC.
An additional
lead plugged between the 5V power connector coming from the monitor and
the 5V-socket of the CPC.
There were three
versions in all.
The tape software
is : AMX Art.
The AMX Art software
uses the CPC's 300Hz interrupt to read the joystick port (at least it tries
to do that, while moving the mouse pointer, the software accidently disables
IRQs, and so, misses some interrupts). This is giving it a relative low
resolution of max 300 mickeys per second (or actually less, due to the
missed IRQs).
The AMX Interface
hardware basically converts the incoming mouse signals to joystick signals,
issuing LOW pulses (per mickey) on the corresponding direction lines. The
protocol is thus very simple (unlike modern RS232 and PS/2 mice, the hardware
doesn't contain any motion counters).
Note: The exact
hardware timings are unknown, the values "1/300s" in the above description
assume that the AMX hardware timings were designed to match up with the
300Hz AMX software timings.
Note II: Looking
at the photos, it seems that /joystick1 (keyb row 9 select) is wired to
the multivibrator, so the mickey timings may be software controlled; accordingly,
software would be required to deselect keyb row 9 between each read.
Contains the
following ICs:
1x CD4047BE -
Low Power Monostable/Astable Multivibrator
2x MC14013B -
Dual Type D Flip-Flops
1x SN74LS244N
- Octal Buffers And Line Drivers With 3-State Outputs
The mouse used
on the Amstrad appears to be the same as the mouse used on the BBC. But
this is not confirmed. The connection to the interface is essentially the
same. |

It was known as
very "professional" joystick, at least in Poland. And it was very expensive.
But technology was the same, microswitches, the only new things were 3-level
autofire, additional Fire buttons and stopwatch.
Stopwatch required
1 AA 1.5V cell. It can count down in minutes and, when time goes out, it
beeps until button is pressed.

CPC - QUICKSHOT
TURBO JOYSTICK
Legendary joystick
from Quickshot. With auto fire function. Compatible with Amstrad CPC, Atari
400 / 800 & VCS, Commodore 64, Vic 20 and more. The difference between
this Turbo version and the regular version, is that the turbo uses microswitches,
making it far more reliable and responsive.
Marketed as QuickShot
II Turbo, or QS-111 (licensed versions), was quite good as it used microswitches.
However, some units are equipped with metal contacts.
