The Sinclair QL Forum

I'm glad to share my last QL hardware project : The GC QL mouse adaptor.
This allow the use of a standard PS2/USB mouse with the QL.
It is connected to the QL via the CTL1 port (no hardware modifications are requested on the QL).
The 5V power come from a low power PSU or from the QL via the external ROM port.

NOTE : only PS2 compatible mouse (even USB) can be used. USB mode only mouse doesn't work with this board.

Thank you for sharing this project.
I presume that the mouse emulates cursor keys, like a joystick connected to CTL port?

Or is it sermouse compatible?

No, it is not sermouse compatible, it is a PS2 to joystick (CTL1) converter

Exactly !
I have tested it with ICE with good results.

Has anybody made this interface ?

Any feedback ?

Gianni

I am waiting for all parts to arrive .

As soon as the project is finished i will let you know.


pcb has been screened , now to find some time to etch it .......................



techy



btw , will it work with dilwyn's launchpad too ??


update !!

several parts arrived by snailmail , including a genuine microsoft usb mouse .

update 2

pic has arrived and is already programmed .

Finally found time to finish this project.

Still not sure if the cable connection will stay this way or updated to the db9 version.

Unfortunately no place to do real testing as my working space is covered in many other projects..........

And an update ,


I decided to go for the db9 connectors .

The pcb-connector is very expensive at my local electronics shop , so i had to wait for the postman to arrive with better-priced alternatives.


Looks quite smart now .

Hopefully it will work too.

The pcb has a very good DIY layout , very roomy .

Thanks Gianni .


testing will be for ................ the next couple of weeks.

Looks great, very neat and tidy

Has anyone finished this, from what I can see it is based around a PIC 16F84A microcontroller and a couple of 4066 doing a lot of switching, I assume some programming involved? Could be useful for other projects if it interfaces with the QL in-ports and a USB?

A data sheet for the PIC here : http://ww1.microchip.com/downloads/en/D ... 35007b.pdf and the 4066 here : http://eeshop.unl.edu/pdf/CD4066BC.pdf
