Howdy Bruceee. Yeah, I hang out at the Adult Beginners' forum, too. And to tell ya the truth, I didn't know about this forum until I gave my infamous "I'm not going away mad" speech...so to speech.
Someone mentioned it there and I checked it out. Duh. Some daze I ain't the sharpest knife in the drawer, either.
I don't play so much from memory as by ear. I make notes for myself on my computer (which is generally outta the picture) and play along with mp3 files. The notes tell me what key to start in and I go on from there. It worked very well for the bass and with the little electronic keyboard, but it's only gonna go so far with the organ...although I spent a little time ignoring the noisy bearing in hopes that it would quiet down...and it did, to an extent. I put some Eric Clapton blues on WinAmp and went to it. It was easy to play the 1-4-5 chord pattern, but I've got a whole lot to learn.
The pic of the back of the Hammond is kinda typical. My son took it as we were locking the tone generator down for shipment. So far, I've spent a whole lot more time behind and inside it than at the manuals. I've also donated a lotta blood to it. In case ya didn't know, there's a lotta sharp stuff in there!
I was also an electronics tech, starting in the military with radar and a vacuum tube analog computer, so this stuff is familiar, at least. Especially the smell of hot tubes (I guess you call 'em valves there.)

For the last 20 years of my career I wrote financial software...mainly interfaces between different computers and software packages for a large hospital management company. So I've been on both sides of the hardware/software bridge.
I hope ya get a chance to fix yer "clone-wheel" (if that's really what it is) and play it a bit. I really, really love the tonewheel sound.
Drop me a PM if ya want a buncha links I've found to other organ and Hammond sites.
And for a chance I get to gloat to a Kiwi that we're heading for summer here. I have several Kiwi friends (one of whom I met on the salt flats a coupla years ago...and he ordained me an honorary Kiwi...but I haven't been able to master the language
) in the racing world and they seem to love taunting us as we bemoan the end of racing season and they tell us how lovely the weather is there and how they're all going to head for Lake Gairdner in Aus while we're freezing. My turn.
Best regards, mate,
