Umm, what gave you that idea?
To be honest, at this point, I'm probably going to make all three variants...  The multi-voice boards will be first, since I'm pretty much done with them already. I still have to decide about the potentiometers, board sizes and mounting holes for the individual voices...

Two things need to happen before I make new boards. 1) This batch of MB-808's has to be out the door, and 2) I want to build prototypes of each new board before I order and ship the final versions. I'll be back from my business trip in mid October, so I'm hoping to get the MB-808's out the door by the end of October. (/me crosses his fingers for luck.)
That said, I'm hoping for November some time. Of course, all of us developer types are optimists...

I´m not in a hurry,no problem here.
Are there some leftovers for the next MB808 run or are all boards/kits spoken for? Maybe I should jump on this train...
Kind regards

All of the third batch kits are spoken for. I'll be making a fourth batch of kits, since I had to buy parts for 250 kits. (For example, the minimum order quantity for the colored switches was 1000, and each kit takes four.)
If the fourth batch is anything like the third, I'll have a bunch of people on the waiting list, but only about a quarter of them will actually buy...

Roughly speaking (it depends on the cost of pcb manufacturing, and I won't find out the final cost until I actually place the order) the kit from me is about $200, and you'll need about $150 of parts from Mouser or likesuchas, plus a toroid for the power supply. The one I use is about $30 from Digikey. That will get you a fully functioning 808 sound generator with MIDIbox sequencer.
After that, you'll need some kind of case. Most of the guys have been getting a Hammond 1456RL1 and then having Front Panel Express cut the holes and either having the top silkscreened or printing an overlay to stick on...

| Can I trigger the 808 sounds from a DR110? |

Anybody have a DR110 I can borrow?
I'm really slow, but I *will* get it back to you eventually...

The 808 is active high, and the DR-110 is active low, so you have to invert the signal. You can use a transistor for every trigger or a couple of 4069 (each will invert 6 triggers).
Also the DR-110 have a trigger output (is activated with the accent) that you can use as is, without any mod.
