Additional clockports for the A1200 ?
« on: July 08, 2004, 11:55:37 PM »
Hi there,

Is there anyway to connect more than one one device to the clockport of the A1200 ?

I'd like to connect up a soundcard AND and Subway USB device ?

I seem to remember that there was a widget around that would allow it.

Any ideas ?

Thanks!

What this space!

Someone very skilled in electronics, who we've all probably got something from, "might" be doing something most generous about this :-)

I'll post up more info later if it happens.

:-)  Instructions on how to build your own clock port expander have just appeared in my in-box  :-)

I'll see if I can turn them into a schematic and then take things from there.

Some people in the Amiga community are top notch  :-D

...and YOU with the schematics in the INBOX: Share-em!!  



I intend too, just need to get a nice schematic done and get them QA'd .. then up on Aminet they go :-)

The design you have, does it look like this?


I forgot I had this.

This required a connection to the Kickstart chip to provide the extra address decode needed.

I also found a picture of the original quadroport here: http://amiga.resource.cx/gallery/Quaddddroport.jpg

Bye


:-)

That looks pretty close to the description I got ... darn it  spoilt all the fun, but did answer a question I had :-)

Is this something you drew up ?  What are the implications of loading this up to Aminet ?

I'll still make some schematics up though as I can then get the PCB built quickly.

Thanks for that! :-)
