I have some problems with my internal clock A501. It doesn't work anymore.It stays on the same time . I can set it to a new time but it then just stays on that time. I had the same problems about 1.5 years ago. I then replaced the left CIA (8520) and everything was fine. I know the same CIA is malfunctioning now ( I switched the 2 , and the clock worked but another problem occured). I can buy another CIA but I like to know what could be the problem . I think I know what it is but maybe someone could comment on it. I noticed that I have a problem with the ground. Sometimes when I plug in the printer cable I see litle sparks . I also noticed that when I take a wire and connect the ground (of the house , not of my computer) with the outside of my stereo (which is connected to the Amiga) the fuses blow. This doesn't happen when I unplug the audio So I think there is something wrong with the ground of my Amiga (or maybe the powersupply?) Maybe someone had a similar problem or whatever .... -- |bosman@fwi.uva.nl // | Dont't loose your head,to gain a minute, | | \\ //AMIGA | you need your head,your brains are in it. | | \// | | "We are going to have peace,even if we have to fight for it" -EISENHOWER-

Well, if you keep power in your Amiga ON, when plugging the cable,
then you have made terrible mistake. You have to turn off your Amiga
before changing wires. If you don`t then CIA-chips will continue to
break in future too. If I recall right you shouldn`t even switch mouse
or joystick cables when power is on (well I don`t think this is as
bad as changing diskdrive or printer cables).
