I will first of all admit I have no idea what I'm talking about so please tell me why I'm stupid just not that I am.
I have a need to reprogram my old RCU810 and realized that I don't have printer port anymore, and being a cheapskate I don't want to pay $20 to program this remote once.
I looked at my Raspberry PI with all it's GPIO pins and wondered if it were possible to make a GPIO to JP1 adapter?
I have no idea how any of this actually works I just follow the guides but it seems reasonable.

Sounds like a fun project, but a huge undertaking. The GPIO ports could probably bit bang just like the old EEPROM interface. But you also have to consider that your program will have to process whatever file IR spits out, so that's quite a bit of code there as well plus time to debug. And you'd have to do some circuit design to get the voltages right. That many hours of effort is worth more than $20 to me.

I'd recommend just buying a new JP1 remote that comes with a USB cable. They start at $15.

Realize that you can also do a lot of programming on the 810 itself without a cable.

Or, add a parallel port to your current PC for $4

Thanks guys I Acutally have 2 Acoustic Research ARRX15G and I recently bought a Nevo C2 so I am very familiar with the USB varietals but My trusty 810 doesn't have buttons that fail and is slightly more SAF.
