|
---|
46 | *
|
---|
47 | * The Microsoft Bus Mouse was an early mouse sold by Microsoft, originally
|
---|
48 | * introduced in 1983. The mouse had a D-shaped 9-pin connector which plugged
|
---|
49 | * into a small ISA add-in board.
|
---|
50 | *
|
---|
51 | * The mouse itself was very simple (compared to a serial mouse) and most of the
|
---|
52 | * logic was located on the ISA board. Later, Microsoft sold an InPort mouse,
|
---|
53 | * which was also called a "bus mouse", but used a different interface.
|
---|
54 | *
|
---|
55 | * Microsoft part numbers for the Bus Mouse were 037-099 (100 ppi)
|
---|
56 | * and 037-199 (200 ppi).
|
---|
57 | *
|
---|
58 | * The Bus Mouse adapter included IRQ configuration jumpers (ref. MS article
|
---|
59 | * Q12230). The IRQ could be set to one of 2, 3, 4, 5. The typical setting
|
---|
60 | * would be IRQ 2 for a PC/XT and IRQ 5 for an AT compatible. Because IRQ 5
|
---|
61 | * may conflict with a SoundBlaster or a PCI device, this device defaults to
|
---|
62 | * IRQ 3. Note that IRQ 3 is also used by the COM 2 device, not often needed.
|
---|
63 | *
|
---|
64 | * The ISA adapter was built around an Intel 8255A compatible chip (ref.
|
---|
65 | * MS article Q46369). Once enabled, the adapter raises the configured IRQ
|
---|
66 | * 30 times per second; the rate is not configurable. The interrupts
|
---|
67 | * occur regardless of whether the mouse state has changed or not.
|
---|
68 | *
|
---|
69 | * To function properly, the 8255A must be programmed as follows:
|
---|
70 | * - Port A: Input. Used to read motion deltas and button states.
|
---|
71 | * - Port B: Output. Not used except for mouse detection.
|
---|
72 | * - Port C: Split. Upper bits set as output, used for control purposes.
|
---|
73 | * Lower bits set as input, reflecting IRQ state.
|
---|
74 | *
|
---|
75 | * Detailed information was gleaned from Windows and OS/2 DDK mouse samples.
