Hi all.
I have copied my question/post, from another forum. Yes I know. I am just a tiny bit lazy and did not want to write it all again. :-D
Let me start my question, by saying that I am noob in reading schematics. Yet I have a tiny question on if I am reading the schematics correctly.
I have this project, in were it would be so awesomme, if I was able to add a reset button to an Amiga500 board. Now, I thought that it was not possible, and that the Amiga 500 was only able to do hardware reset by doing it on the keyboard. Yet now I am really not sure if that is an urban myth or something.
Well...
I was looking in my 500 manual for a different reason, and I thought that it would be fun, just to look at the schematics in the back of the book. And on the first page, there is a mention of JP1, being the jumper for system reset vs keyboard reset. Then I looked at the 7th page of the schematics, in were the JP1 is found. It was marked as going to "_kbreset" and finally on the 6th page, the "_kbreset" is actually Pin6 on the connector for the keyboard.
Well...
That was a bit interresting I thought, and I found a picture of an Rev6a board that I have, and found the actual JP1 right below the transistor a bit to the right from were RESET is on the silk screen. And sure enough, the jumper is bridged by a solder blob.
Now. If I remove the solder blob, and solder in a couple of jumper pins. Would this be possible to insert a switch from a PC-Case and if the switch is a momentary off switch, then I would actually be able to use both the switch and the keyboard. Are my reading of the schematics correct?
