PS/2 mouse to Amiga DB9 adapter

It’s time for something more complicated than rewiring premade stuff. After joysticks and gamepads, next thing that you can’t replace that easy is the mouse. After searching the net for a bit I found the solution on Aminet. Small device with microcontroller (MCU for short) that translates signals from standard PC PS/2 type mouse to signal Amiga understands. I also found versions with USB connector, but it’s actually a bit of deception. “Real” USB mice aren’t supported. As far as I understood there are too many variations in USB implementations to implement USB support with these small microcontrollers. It is possible, but it would need more powerful MCU and would subsequently cost more. It could be made with simple MCU but then it would work only with mouse type that it was tested with during development, even so far that it could happen to work only with that specific model, not the whole brand.

DIY Joystick/Mouse extension cord

Gamepads from previous article have pretty short cable, unless you’re going to have computer in your lap. All in all not really practical. So, next step is making extension cord.

Basically it’s simple, connect corresponding pins on two connectors (pin 1 from one to pin 1 from the second and so on). Connectors are not the problem, you’ll need one female and one male DB9 connector. They’re pretty standard thing in electronics shop, and there’s bunch of them on ebay.

The real problem is the cable. Joystick connector has 9 pins, that means we’ll need (at least) 9 pin cable, that’s where I got stuck. Here in Croatia there aren’t that many electronics shops and I haven’t found similar cables in shops that sell tools and similar stuff. Problem is that they’re kinda pricey. I’ve found 10 wire round cable but price was almost $3 per meter (one meter is 3.28 feet, you can round it to 3 feet for easier math 🙂 ) . I planned to make two cables of at least 2 meter in length (cca 6 feet), that would make $12 just for the cable. There are cheaper ones, but they’re flat cables and that doesn’t look that practical.
