Digital keyboard on the way

I purchased a used Yamaha digital keyboard at an online auction and the nit should arrive tomorrow.
The PSR-GX76 is an entry level keyboar, some years old, but I want to try MIDI with my laptop and sound system. I'll use Csound, the software suite from MIT, to map a Hammond B3 Csound instrument onto the keyboard.

I have a 1968 Hammond H-182, touted by some as a Super B3, but I'm interested in MIDI programming.
The keyboard is not as sophosticated as I would like, but the price was right for an experimental instrument and there are 76 keys, a deciding factor. The only thing better would have been a full 88.

I've already received a power charger, purchased from eBay, to replace the one not accomanying the keyboard.

I may need a special cable to go between the keyboard an my laptop. I'll have to order one after I've set up the GX76.
