Hi, It literally hadn't crossed my mind about the UK power supply not working in the US i did a quick search of Ebay and here's a couple of options that should work! http://www.ebay.com/itm/Commodore-64-Power-Adapter-Supply-C64-C128-SX64-Tested-Working-C64C-/120855549290?pt=LH_DefaultDomain_0&hash=item1c238d556a http://www.ebay.com/itm/COMMODORE-C64-64C-1541-1541II-1581-Custom-Replacement-Power-Supply-NEW-/300661417147?pt=LH_DefaultDomain_0&hash=item4600d124bb

SOLD!!

Ok I'm selling my MB-6582 with power supply, i should mention the face panel has a small scratch about an inch,it has 8 6582a SID chips installed see pics! ,make me an offer if you're interested i'm in UK i can post to EU.

Hi, I'd like to sell my MB-6582, i have no time to use it and unfortunatly its gathering dust, would it be ok to sell it within the MIDIbox community? Thanks

Update pots sold!!

For sale 4x 500k 16mm dual gang pots £2 for the lot .

Yeah i did solder the larger Capacitors in before the IC sockets which was a bit of a mistake ,but i just bent a couple of the legs on the IC sockets to hold them in place which worked ok,if i were to build another the larger components would go in last for sure.

Hey folks, Just about finished this MB-6582 ,all thats left to do is fit the feedback pots! I'm more than pleased with this Synthesizer,the only problems i had with the build was 2 led's didn't work which i have replaced now, also i didn't read the instructions properly on the length of cable between the base PCB and CS PCB ,i used 3 inches of cable and it ended up i couldn't close the case!. The panel is from Julianf and knobs were courtesy of bhc303 and thanks to Wilba for the great instruction guides. If you want to see some more pics here's a link to my Photobucket page http://s259.photobucket.com/albums/hh302/taftert/MB-6582/

Hi, Got the knobs in the post this morning, thanks for the speedy delivery

Hey , For the 6581 chip you'll be wanting to use the 470pf filter caps ,this is a good guide http://avishowtech.com/mbhp/mbhp_SIDR3a.html

Hey, i built a similar optimised psu on vero board with a slightly different board layout, i was really chuffed the first time i powered it up and it worked here's a couple of pics

Hi, Thanks ! I have some 24LC512's on the way and a bankstick pcb from Mike's midi shop, though i think finding space inside the box for the 8 bankstick is going to be tricky !

Hey folks, I just finished installing the second core to my Midibox Sid and everthing seems to work,next step is to aquire a couple of Sid chips and solder the Sid modules

Hi, Yep that was the problem, its working fine now! Thanks

Hi, I'm looking for some advice ,i have been trying to load the bank midibox_sid_presets_8580.syx into Midibox Sid V2 editor and i get this error message "This file does not contain a bank with 64 or 128 valid patches" has anyone any idea what could be causing this, i'm using winxp and the latest java ,the editor is talking to the sid as i can edit the patches ? Thanks for looking!!

Hi folks , Just finished building a Midibox Sid so i have used it in one of my tracks "lights" on my website check it out here http://www.myspace.com/taftert

Hi, Ok new lcd succesfully installed ! managed to change midi channel ,was responding on channel 6 also stated it was on 6 on lcd , when i rebooted the Sid it went back to channel 1 I have searched the forum and the closest thing i could find to this was here http://www.midibox.org/forum/index.php/topic,11173.0.html but it looks like he has a v1 Sid . thanks

Hi, Its still on midi channel 1 as far as i can tell ,my lcd is damaged and has become unreadable ,i have another one in the post though !

Hi, When i send the command it seems to go into a loop SYSX: F0 00 00 7E 4B 00 0F 01 F7 00063A24 1 4 F0 Buffer: 9 Bytes System Exclusive this is what it says

Hi, Its a V2 ,it could be that i haven't set up the Midi-Ox software correctly ,i will have another go at it ! Thanks

Hi , I have been trying to change my Sid's midi channel via sysex using this command "F0 00 00 7E 4B 00 06 70 00 10 05 00 F7" ,for midi channel 6 the problem is it doesn't change ,the sid seems to be working ok in regards to receiving midi as it can play notes form the keyboard in mios studio and i can get patches onto the bankstick ,am i using the right sysex command? ,the program i am using is Midi-ox . Thanks

Ok ,thanks for the help much appreciated !

Hi, I forgot to mention previosly to wiring up the lcd module properly i had wired it up wrong and when switched it on it got warm and didn't work, so that might have damaged the internals slightly ,also when building the core the only changed i made to the module was to leave out the voltage regulator and bridge rectifier as i was using the optimized psu .

Hi , The voltage regulators on the Sid modules dont seem to get hot or even warm neither does the one on the psu board !,one thing i have just noticed is the trim pot for lcd luminocity doesn't seem to be doing anything !

Hi folks, I have just finished wiring up my Midibox Sid and optimized PSU,switched it on and everthing was working ok untill after about an hour when now the lcd has an intermittent fault, there is a line missing from the top line of characters, this comes and goes ,i have checked for shorts etc and cant seem to find anything ,i am using the 4685 pic and the lcd is wired up for 4 bit operation ,is this problem likely to be a dodgy lcd module or could it be a problem with the core ?. The other issue i have is the core doesn't seem to accept patch updates to the bankstick i have managed to get the vintage presets onto the bankstick using Sysexbox ,it only worked once now i cant seem to change the preset patches. Thanks for looking !!
