Hi darkage.

Thanks for all the info.
That really helps identify the receiver ( ? LDR ? Light Dependant Resistor ?).
The circuit is similar, but mine is an early one that came with an OLD 500.

Good to hear from somebody located in Victoria.
Thanks Again      Ray

Thanks for the info.
I am using Pavel's Circuit as a reference, The other one is totally different.
Included is a photo of the Old Tired Mouse.

Hi @darkage and @Pat the Cat.

Problem Sorted  ?
The load on the IR Reciever was to low (Original Design) which was 670 Ohms.
Now modified to 2.7K ohms as per Pavel Ruzicka's Circuit.
I have changed all 5 Resistors to this standard.

Thanks for all your help.

@darkage

It looks like the 3 that I had problems with, were all with the low value resistors ??
Pavel's Circuit did not match the Old Tank Mouse, But i used it as an example of how a mouse could be wired.

Thanks    Ray

Ok Thanks for the journey down the Ohms law road I haven't reviewed that for a lot of years.
Ps :- I am an Old techo, and i still like some of these challenges.
Thanks again
