Amiga 500 Tower Reset problem
« on: August 22, 2004, 07:36:36 AM »
Hi Everybody,

As most of you now know, I built myself an Amiga 500 Tower.  I would like to be able to reset the computer using the reset button on the front of the massive vintage tower case.  How do I do it?   :roll:

Hi Jope,

A computer engineer of your pedigree, who's owned and repaired every computer known to man probably knows that many computers can be reset by grounding the reset signal.


Yes, I already know this, but grounding the reset pin on the 68000 processor does not work on the Amiga 500 motherboard.  The "reset circuitry" is part of an Amiga 500 keyboard, but is not on the Amiga 2000 keyboard.  On the Amiga 2000 the "reset circuitry" is on the motherboard.  So, in order to install an Amiga 500 board into a Tower case and then use an Amiga 2000 keyboard with that tower, you have to build the reset circuitry and hook it up to the reset button on the case.  The "reset circuitry" board consists of two or three ICs and a few resisters and caps.  I know that there are detailed instructions somewhere on the internet that explains how to build this reset board.  That is what I need.

Is it nice to have ruined your reputation in the eyes of many? I mean all that arrogance about knowing everything in the world and then you can't even figure out something like this?


I have not ruined my reputation and I never stated that I "know everything in the world".  Personally, I think that you just do not like me, but that's ok.

Naturally, if you blow up your computer after following my advice, then it's your fault for not thoroughly researching the answers you get - after all, I do NOT know what I'm talking about.


Actually, you don't know what you are talking about.   :lol:

Have you tried a button between pin 5 of Gary (U5) and ground?


No I have not.  Is that suppose to work?   :-o

Hi Jope,

Now you have impressed me, which is not an easy thing to do.  I now believe that you do have more Amiga knowledge then the average Amiga user.  Thanks for the reply.  It was very helpful.   :-D

Now can we just get along?   :lol:
