Well, I see you are already on organforum.org. Unfortunately kikennon's thread on ultra cheap midi implementation has disappeared. He was giving away software to scan $29 scanner boards. He had a website, kikennon.com, which I haven't checked lately. Midi-boutique is for rich people. Wait til after the holiday, I'll tickle the moderator at organforum to make kikennon's post show again. The PC source is up to you, but the soltware, jorgan, is free. You can also buy old sampler synths like the Ensoniq EPS for about $100, if you can get the keys to midi format.
As far as moving the organ, a 4 wheel 1200 lb dolly from mcmaster.com makes anything under 400 lb a snap if you don't have to go up stairs. The guy that helps me move pianos has a hernia and doesn't do much but balance the piano to not fall over, and stack up boards under the end I just lifted until I get it on or off the dolly. We used 11' ramps from U-haul-Ryder trucks to get out of houses and into the truck, and vice versa. Into my house which is 7 steps up we would strap the organ up (400 lb) to a port-a-pull and winch it up the ramp into the house.

The old Conn I had long ago had a single oscillator per pitch with multiple contacts per key turning on 16', 8', 4', 2 2/3' and 2' pitches. The oscillators run continuously and are not locked to anything. Each of those 'transformers' are actually inductors with a spring loaded 'I' piece next to the 'E' core. Adjusting the nut at the spring changes the inductance and tunes the oscillator. A truly dreadful musical appliance. It's already analog so 'converting' it would be replacing the oscillator array with a new tone generator system. Not inpossible but not trivial. Yours looks very much like mine including the gas regulator for a 75V supply. I replaced that with an amplified Zener diode.

Look into the Hauptwerk system by Milan Digital audio. That will be an instrument, not an appliance (as most electronic 'organs' are).

Forgot to mention, I wrote keyboard scanning software (assembly) for a pipe organ I built in '89. It runs on an MCS-51 family processor but is easily converted to 68HC908 family. My software was for a dual contact X-Y array to get MIDI velocity on a 5 octave keyboard (I made some changes to use on an 88 note piano keyboard) but could be easily changed to use single contact with fixed velocity. Free to a home if interested.

If your yellow tubes don't have a plus on one end or minus on the other, they are not electrolytic. Also, if the value is less than 1 mf they are more likely paper dielectric. Paper dielectric deteriorates some over the years, but if nicely sealed up with wax (as the high quality ones were) they hold up way better than electrolytic. Paper caps don't explode, either, as electrolytics can in the power supply near the power amp.
I found Mr Kikennon's thread on his giveaway scanning software for a cheap commercial key scanning PCB, MIDI Programs Posted I'm thinking of buying some of these for my H to add midi controlled sounds. Hauptwerk as mentioned above, is, I believe, even more expensive than midi-boutique, and runs on a fairly capable PC. The diy'ers in organforum are running more to jorgan for PC's which see.
I've got some Intel 8051 PCB's from the early 80's, but they are not the intel brand MCS-51 board, so I doubt Stratus46's software would help me. Thanks anyway. Not much chance of finding a PROM programmer for those obsolete PROM's, either. Mr. Kikennon's stuff runs on allegedly currently available technology. Several people on organforum warn against implementing matrix keying, as opposed to 1 at a time, and the Conn is definitely a 1 at a time box as now wired. Again, much thanks for the offer.
Lot more knowledge is available on organ forum, firepowerforfreedom, so if you get into this start a thread on the midi section over there. Sorry I didn't see your posts. Midi-boutique is a painless solution, but way above my budget now, and perhaps, yours.

That's perfectóI'm definitely going to miditize this thing now, barring any accidents or excessive hidden costs. I think I'll slice off the bottom box and just use the top console, then get it a stand. Thanks for your advice and help, guys!
