Fist of all, i'd like to thank Moosmann for his website: http://mbrandel.vizionaires.net/?page_id=48  This is how I discovered the MC14551 IC. I was originally looking for a single chip solution, but 2 is small enough for now.

My goal was to make this as small as I could, and i'm pretty happy with the results. The 8pdt switches work great, but are very difficult to fit into PC Engine GT/TurboExpress. Also, i'm a little paranoid about the longevity of the 8pdt switches because of the amount of contacts. This only uses one very common switch.

Forgive the crappy pic. My digicam broke, so I used a scanner to take this. The traces were shiny, so the scanner made them look like garbage.



Its pretty straight-forward. You hook one pin to the pcb, one pin to the hucard slot. Its connections are all in order, 15-23 (skipping 18 of course). So if you wanted you could use ribbon cable.

I have a bunch of these extra, and can sell them for $20 -shipped- in the US. I know thats a little expensive, but believe me i'm not really making much profit. The ICs are cheap, but making a relativly small quantity of PCBs is pricey. I just thought it would be helpful to a few folks here.

I want one

I'm intrested in one too.  Please let me know when you start accepting payment for them!

Send me a PM here, email at rioninja@gmail.com, or on AIM as "rioninja". I can take pretty much any kind of payment.  

This is so rad.

I have one of these on the way and I will be documenting the installation process with tons O pics!

B)  

Got mine This PCB is uber small and is very well built.

Time for the install...
