Test your PC keyboard

[VELESOFT]

Например: нельзя нажать 3+4+5, 9+4+5, 3+7+6, 9+7+6, ну скажем, D+K+I и так далее...

Yes, 3+4+5 is possible use, but I need test all combinations used in game controll (sinclair 1, sinclair 2 etc...)
3+4+5 = down+up+fire -> this key combinations is not used in games.
Is useless test any combinations of reverse directions (up+down or left+right)

SINCLAIR 1 need only this combinations:
6+8+0
6+9+0
7+8+0
7+9+0

SINCLAIR 2 need only this combinations:
1+3+5
1+4+5
2+3+5
2+4+5

QWERT conrol (PSSST game) need only this combinations:
Q+E+T
Q+R+T
W+E+T
W+R+T

QAOPM control need only this combinations:
Q+P+M
Q+O+M
A+O+M
A+P+M

QAOP SPACE control need only this combinations:
Q+P+SPACE
Q+O+SPACE
A+O+SPACE
A+P+SPACE

etc.......

Many modern PC keyboards use same key matrix(membrane layout), but not all !!! USB keyboard for MACINTOSH work without problem, support all this combinations.

Please test your keyboards, I need know PC/laptop keyboards which accept this combinations.
