View Full Version : Mega STE Keyboard and mouse

February 27th, 2011, 01:44 PM
I recently acquired a Mega STE with everything but a keyboard and mouse. I am having the hardest time finding a keyboard and mouse and was wondering if anyone knew of a way to adapt other easier to find ps/2, AT or even USB to the Mega STE's RJ11 type input, or where I can find compatible keyboards and mice. Any help would be very much appreciated. Thanks all!

Well, after much sleuthing I found out that the wiring of the Atari Mega STe is that of a RJ12, so I found an RJ12 to DB9 adapter and then I found a DB9 to PS/2 adapter. Now I just need to find out if I need a data RJ12 cable or a voice because the wiring is reversed between the two.

Check out some of the Amiga to PS/2 or USB mouse converters. Many support the ST as well. As for the keyboard... good luck! I'm not sure about alternatives for that one...

The Mega Ste sure does have a unique keyboard connection. At first I thought it was same as the old Mac but then I realized thats 4p4c RJ11 while the Mega Ste is 6p6c rj12. I hope my little adapter works, if not, I won't be out much. I read that its possible to use a serial mouse with the Mega STe, does anyone know if you need to load drivers?

Oh wow, that's right... Mega STe :) I'm thinking ST/STf/STfm/STe... So the Amiga mouse adapters won't work :( sorry about that - didn't read carefully enough

Its cool, I appreciate any suggestions.

If you want to use a PC keyboard and mouse then you need an Eiffell interface.


These some times come up on E-Bay. How competenta are you with hardware? I think I have some "rough" PCBs

You will not be able to connect a PC keyboard to the ST just by using passive adapters as these two use different protocols.

if you look you will see that the Eiffell interface isn't passive, its PIC based and has sockets for a PS/2 Keyboard and mouse and a couple of Atari joysticks...

Wasn't talking about the Eiffel interface in particular. I was refering to the original poster's idea of using socket adapters.
