Ever seen one of these? AT PC keyboard to 1200 mobo mod. Solder yourself jobby...

I've got one of these...

The data sheet shows you how to solder to the internals of a 1200. As far as I can see, this is only of use if you're thinking about installing an 1200 mobo into a bespoke custom case.

Anybody have any thoughts about adapting it so we can plug it into a CD32 (WITHOUT soldering to internals)?

I can scan the data sheet tomorrow at work if you're interested.

Hi mancalledSun,

Yes, please scan the data sheet. It should certainly be possible to adapt it for use with the CD32 without internal soldering.

That is the same as the one i got for the A600, and logically speaking, you got it from Dart Computers. I have posted a few pics of the internals last year ( http://eab.abime.net/showthread.php?t=42948 )

yes i had one it was in the early days of towering amiga 1200's
takes a signal of a pin on the controler chip you had to solder it on
not an easy task due to the small smt chips of a1200's so should
be possible on cd32

That's the one. It's from Dart.

Datasheet attached - I won't bother taking apart now - thanks salax54.

I'm sure it would go inside a CD32, but could we attach it via one of the inputs instead?

The CD32 has a keyboard input so it may be possible to plug it in there. Someone will have to work out which wire does what from your PDF and the A1200 schematics. (Easy to find using google)

Worse case, sell it to someone with an A1200 tower and buy a Lyra instead?

Already had that in mind. But where's the fun in that?

@mancalledSun:
This gadget -just like most keyboard interfaces- involves the use of a PIC. The fun of it would be for you to be able to program such a chip and build one completely on your own! :-) Lots of similar project if you google a bit.. I seem to recall Ian Stedman had an EPIC board for his CD32. And by the way, as i read, most Amiga "external keyboards" plug to the AUX port, either directly, or by using a cheapo adaptor!
