Re: ACIA mouse question

Hi Doug,

> are you doing anything that specifically relies on this?

Yes, ;)

I'm writting an ACIA IKBD rout (helped by some code found on this forum) to manage my joystick/keyboard/mouse.

It works well except in this special case, because the "extra" bytes are taken into account as keyboard inputs and this generates some "wrong key input".

IKBD_Main: btst #0,$fffffc00.w
beq.s ikbd_endit
movem.l d0-d1/a0,-(sp)
move.b $fffffc02.w,d0
cmp.b #$ff,d0
beq.s ikbd_yes_joystick1
cmp.b #$fe,d0
beq.s ikbd_yes_joystick0
cmp.b #$f8,d0
bmi.s ikbd_no_mouse
cmp.b #$fc,d0
bpl.s ikbd_no_mouse

I'd like to know how to detect this extra byte to avoid the "false" keyboard inputs.

Message board and comments are now read-only

Due to abuse of the message boards we have put the entire site in read-only mode. That means you can't post new threads or reply to old messages and you can't add comments in VideoDB and PicDB.

Some messages have been erased from reading, but are stored in case they need to surface again.

After 17 years and 45000 messages we're shutting down due to one person.
