Hola! - hab den mb6582 mit nem 5€ löteisen vom obi mit immer nachgefeilter 2.5mm kupferspitze gelötet, hab aber mittlerweile geupgraded und muß sagen, ein anständiger Lötkolben hat was (gell nILS ;-)) - da ich ein warmduscher bin hab ich auf bleifreies lötzinn geupgraded (400°) und Alex hat recht, es arbeitet sich etwas schwerer damit, aber ich bilde mir ein weniger rosa Elefanten nach ein paar Stunden Inhalation zu sehen... - Test von SIDs auch in den entsprechenden 64ern, wo sie herkommen (OSCs und Filter testen), dabei drauf achten 9V und 12V Varianten nicht zu verwursten :) - wenn ein 8580 heut noch geht, glaub ich isses von der Haltbarkeit her egal ob er aus dem jahr 87 oder 92 kam - dann hält er auch nochmal 25 Jahre :) Ciao, Peter

very well done and clean - i have most respect for veroboard cs builders (struggling for myself :-))

Gute Wahl ;-). Es funktionieren alte und neue C64-Netzteile (die "Pyramidenartigen" und die "Bricks") für das MB6582 mit Power-Option B (Mischbestückung von SIDs möglich). * Ich vermute mal daß der Weg 9V + 5V = 14 V + Spannungsregler = 12V gewählt wurde, um den Strombedarf von bis zu 8 alten 6581ern zu decken, aber das ist wilde Spekulation :-) * Möglicherweise liefern die neuen Netzteile keine 12V mehr und deswegen wurde dieser Weg gewählt ;-) * Einzelne Reports von unzuverlässigen C64-Netzteilen ("fried SIDs", sehr unschön) führten übrigens dazu, daß sich einige Leute neue/eigene Netzteile bauen, wobei man dabei wegen der Audioqualität wohl besser einen Bogen um "Switched" Netzteile machen sollte... die alten C64-PSUs sind noch "linear", das heißt sie verbraten nen Haufen mehr Energie, aber haben wohl ein saubereres Ausgabesignal... Bin kein Hardwareexperte, deswegen lasse ich mich sehr gerne korrigieren, vorallem bei den Punkten, die mit * versehen sind :whistle: Viele Grüße, Peter

stümmt, aber ich war so froh, daß ich damit losgelegt hab ;) und das baseboard kit alleine mit Rutgers Patch-Editor macht für den Preis schon richtig was her... :-)

kann man, empfehle Dir aber statt den Einzelmodulen das MB-6582, das ist für alles ausgelegt und ist für 8x SID (auch verschiedene) die meines Erachtens billigste und beste Variante, für die es auch ein geniales Control Surface PCB gibt :-)

no problemo :-) btw., I will update this tutorial, if i can find a VFD that somehow fits into the mb6582 case, i´ve gotta have one - or at least a display the is really quickly updating, the 9USD display from china drives me insane, it needs a subjective 1+ seconds to update characters, until the old content is not seen anymore (ghosting) :cat:

You are more than welcome and i encourage everyone to build one as this synth rocks the house :-) nILS, what do you think about a move to the SID section, at least until MB-6582 V2 is out? :-)

If it can be found by the community and retrieved by the police, your fingerprints should be all over the interior establishing proof that it was you who assembled the unit.

very nicely done! congratz, and you better sell your sid station soon, as you will not have much use for it now :-)

i hope the sids will catch your absolutely righteous fire of anger and burn down a good part of the burglars stolen things :)

no, this is unacceptable, a windows key on a classic breadbox. noooo... *pullshairs*

The zero ohms +/- 5% resistor, which is loaded when you open the page is great. :-).

Sorry for double posting - just before ordering, I have identified a potential fitting conflict of this VFD, if you look at the vacuum tube and the components on top of the vfd glass case on the right diagram in the datasheet: http://www.farnell.c...heets/14273.pdf they will collide with the top window cutout of the control surface pcb and the tactile switches there, if you look at the second photo here (sometimes i am glad for photo documentation :-)): so either the vfd has to be mounted ca 7mm deeper, which might be problematic because of the already quite stuffed pactec pt-10 or we have a fitting problem... Argh &§"/$(!

I have the feeling that the noritake VFD is not greedy on power, as it is rated the same (275mA) as some LCD backlights. That is a good character trait and makes it really useful as a drop-in lcd replacement :-). Ok, here is a pic with added load on the 5v chain. My setup is a standard C64 power brick, 8x8580 - I am playing some notes on all 8 sids for some time now and so far everything looks stable, will leave it on for a little longer, though... The breadboarded resistors actually only add ca 190mA current consumption on the 5V rail, because my multimeter is a very el-cheapo variant and can´t measure higher currents than 200mA. That´s why I left the backlit LCD connected... in conclusion, if the VFD does not take more than 200mA more than my used backlit LCD (which is rated for 200mA), it will work. Of course, using a newly built custom PSU, you are on the safer side, just make sure that you catch no noise from switching PSUs. Regarding the bulk order - I am not sure, that this is going to happen, as the items are quite pricey and we would need to get 10 people interested in them with cash prepayment for a significant rebate - i would not like to run such a thing for sure, because of the hassles involved. I will order one noritake VFD soon, as I love the MB-6582 (really!) and will keep you posted regarding the compatibility: dimension-wise, as well as driver-wise. I am quite confident now, that for a 8x 9V SID setup (8580/6582) at least the C64 PSU is good enough for use with this VFD.

can you remove the sids and install and run the testtone app (available from the mios8 download page on ucapps.de)? when you run it, is there still only output on one channel and is there still a drop in volume after a few seconds? bye, peter

nILS, the simulator is awesome! thx.

0 *scnr* :-)

* please give us the specs of your new psu * photos taken from the soldered pcb would help us, too * if you are experiencing "mono" output, exchange the sids and check if the "mono" output comes from the other channel afterwards

and frontpanel express can also do blind holes with metric threads in there, which can save you some ´weld if your frontpanel is thick enough (unlikely, if it is 1.5mm for a pt-10 :-))

submitting "ViRal3".. the slow constant stereo pulse comes from the patch itself... the mod matrix of the v2 is almighty! :super: great for drum and bass btw :) the demo (listen with stereo headphones!) was just improvised live on a keyboard using 4 stereo sid channels of the great mb-6582 with feedback mod and feedback cranked up and is otherwise completely uncut/unedited, so expect no wonders as i´m frackin´ tired :-), no fx but a simple echo was added. am a big fan of pink floyd atmospheric sounds, but there is a very very long road ahead :) as i´ve just blamed myself now, you have nothing to lose, we are interested in your patches and demos, c´mon :-) ViRal3.zip ViRalDemo.mp3

very very nice man - will contribute my patches too, but they won´t reach the quality :-)
