cool!
I can redesign this interface for use in russian ZX clones. :v2_wink2:
K-MOUSE interface can use also ports 31(kempston joystick/amiga mouse emulation) of 127(fuller joystick). Both ports is used for FDC controller(beta disk). Must I accept state of signal /DOS(trdos activity) on russian ZX BUS ? K-MOUSE accept only IORQ,RD,WR,ADRESS BUS and DATA. Must be connect signal /IORQGE ? :v2_conf2:

Of course.
Yes, you should use signal /IORQGE, but also, you should notice that some users won`t be happy if Kempston joystick will be disabled by your device. May be you can setup some kind of switch for selecting between Kempston joystick and AMIGAmou/FULLERjoy.
But many other russian interfaces not use /DOS signal.
Signal /DOS is active in zero value (log.0) if TRDOS rom is active ?
If TRDOS is paged-in then signal /IORQ is always disabled ? If it is true, why I must accept signal /DOS ??? :v2_conf2:
K-MOUSE interface contain switch for enable/disable port 31. :v2_smile:

They are not using it cos`:
1. They are not using port #1F;
2. They are blocking Beta Disk ports by asserting IORQGE signal;
3. They are ugly :)
If TRDOS is paged in then you should not assert IORQGE signal, so if /DOS = (equal) 0 then IORQGE should be equal to zero (0) and your device should be disconnected from bus.
Nice! :)
Hi, VELESOFT!
Whether probably to replace the out-of-date controler PIC16F84A on more modern, cheap and accessible, types PIC16F690, PIC16F818/PIC16F819, PIC16F627A/PIC16F628A?
Посмотри внимательно, в архиве с прошивкой http://velesoft.speccy.cz/kmouse/km-...e/km-t_pic.zip есть версия для PIC16F627A/PIC16F628A.
