Clock Port Splitter Schematics
Okay, here's the schematic for my splitter (click to enlarge to full size).

You can see that there are some capacitors in there in an effort to keep digital transients down - Try and put them as close to the new ports as possible, and the 10uf one as close to the IC as possible. And be careful of my renumbered clock port pins!! You're welcome to use this design for your own personal use, but please contact me before using it or any part of it in a commercial capacity.

PCB Layout
As I've said before, I only ever built this as a bunch of wires soldered to the back of the DIL socket for the IC, so I've no idea if this layout is any good. Again,click for full-sized versions.

It's not finished, as the capacitors are missing for each of the new ports, but apart from that it looks alright. The designed dimensions are 90mm x 50mm, just in case anyone wants to try and prototype them, all holes should be through soldered as both sides of the board have traces, and the printing is optional, but have a look anyway as it shows polarities and where some links are required.

Please let me know if you do end up building this, I'd be interested to hear how you get on!! You can contact me here.
