AFAIK, the lines are only un-used for now, that may change in the future...

Seriously, is nobody interested in these?

You could however use it in an FM expander for the C64 ;)

You could perhaps find a shortcut by looking up the code for the ps/2 adapter used for the DTV commodore conversions.

I'd be in if we could get black and white displays that will fit Wilba's case. I'm sure we could easily fill that order!

Sounds to me like it's growing into quite a chip project! I wonder when you mention wavetables, could it produces results like the Elba Monowave? If so, that would be awesome! I know that uses a moog style filter rather than a DCF, but I think I'd prefer the nasty aliasing you get from the DCF. There's all manner of smooth sounding synths, who needs another Moog clone ;)

Jeez, this is a catastrophe! I can't believe an error of this magnitude slipped past on such a simple board! ;) Seriously though, that's a really minor thing to have to correct, if that's all you did wrong on this layou you can feel pretty satisfied with yourself in my view.

So do we know if Smash is going to be offering an MB-6582 kit?? If so, i'd be snapping one up for sure!

I've got a small stockpile of these if anybody is interested. They do have EL backlights, but they can be swapped out if need be, or an inverter could be used. They're £1.25 each, so they're available at that price plus postage. PM me if you're interested, first come, first served.

To be honest, I think that I could live without a backlight on this one, but I wouldn't mind taking a look at the inverter circuit anyway. I was thinking of building a 1kHz oscillator based on a 40106 schmitt trigger, but I'm not sure that could sink enough current.

Yep! I've scored a few 2x20's that have luminescent backlights, so those i'd just not have a backlight on. Obviously, it wouldn't be hard to add some SMT LED's, but they draw more current.

My PCB's and SID's arrived this morning too! I think three or four days to get from Australia to the UK is pretty damned fast! All look in good order too, so hopefully the SID's didn't get x-rayed to death at customs, and I won't get a VAT bill ;)

Anybody know if it's a feasible idea to power an MBSID via batteries?? What's the current draw on 1xCore 1xLCD and 1x6581? Obviously it wouldn't use batteries, but what would be required for it to use the Bassline engine in a 1xSID configuration?

Hey guys, I was in my local electronics goldmine today looking for some microswitches, when I stumbled upon a display of 2x20 LCD's with what appear to be backlights. Obviously, I was intrigued, and instantly thought about my MBSID and MBFM projects to be. So I checked, and they have the correct HD44708 chipset (Hitachi). However, I'm not sure about the backlight, or how it's wired, as I suspect it's an electroluminescent, rather than LCD. If that's the case, I don't mind, I can always source some SMT LED's and use them in place, because I got this LCD rather cheap... £1.25 So, if they're good for Midibox, I'll go back and get them all (I think there were four or five left). The model is LM032LN. I've got the datsheet, but there's no mention of a backlight, so if anyone can help, i'd appreciate it.

Looking at that, I'd question wether it's worth the hassle of doing a group buy for these cases. Once you factor in two lots of shipping, how much cheaper will it be? I'm still on the fence to be honest, I'd like to build a nice mahogany case, but the PT-10 is cheap and it works, so it's a toughie. That said, I'd like an internal PSU, so mahogany may be the winner, but who knows!

Actually, I did some searching and came across the Dtronics DCB to MIDI replacement board. It appears to be a Pic (16F84) that replaces the DCB circuit completely. I'd prefer to homebrew something like that though, especially when that little PIC+PCB costs half as much as the synth itself!

I think it's very cool! If I can find a UK stockist of the Speakjet, this is going on my extensive TO-DO list.....

Is there a reason that last post was loooooooong? I just wanted to mention that Slorrin has the chips in hand, it's not a group buy as such afaik. From what I recall, the chips he bought were pretty costly, so my guess is he can't offer a competitive price, hence the closure.

I think i'd maybe be interested in another set of PCB's at some time in the future, but don't count on me. Having said that, you don't necessarily need 50 people, that's just the point at which you start to get a good price break. I imagine that if you got together 25, you'd get a better price than the $150 individual costs. I wonder if SmashTV has considered fronting some cash and selling the PCB's through his website store??

Ok, so is anybody actually running the group order for these panels? If so, when is the group buy going to start/finish, and when can we stop voting on which artwork to use?

Was DCB populated on the Juno 60 main voice board? I was under the impression it was on a seperate B board with all the memory associated controls. In that case I guess it is a Juno 6 board (but it does have the 60's Test modes, like unison etc). Maybe there's a way to graft onto the keyboard matrix, in a similar way to the Polysix retrofit?? Note on-off would be just fine.

Interesting you should post that in a GROUP BUY thread... Slorrin bought a stock of 8580's to sell on to members of the Prophet64 forum. I imagine there are a few left for Midiboxers too ;)

Just wondering if anybody here has had any luck with a MIDI interface for the Juno 6. I've seen a couple of threads discussing DCB, but no actual work seems to have been done. The Juno i'm looking at looks to have a Ju 60 mainboard in it, probably wouldn't be difficult to add a DCB board, then a MIDI -> DCB converter, but surely there's a better way to just get note on/off via MIDI?? Any ideas?

The PIC is for converting MIDI to DIN sync, and also divided clock outputs (ie, 48ppqn, down to 1/16ppqn). The PIC generates the clock signal, and the decade counters basically select note on or off per 16th note.

That is beautiful!! Can I just check how it will work, i'm still not 100% sure of it's capabilities?? Is it possible to output 8x Gate and 8xCV's from this one board?
