You were right! Unfortunately I made had to make a mess of the PCB to solder all of the bridges in PSU section but now it's fine and I'm reading 5V and 9V. Thanks for the help Jason! Vlad

That is correct, I'm in the same mode on my multimeter for all the voltage readings because I've got no ******* clue how to operate this thing apart from getting some basic input. Yes, I was measuring against ground. However I have built some devices (mgb midi interface) successfully just by following the schematic and instructions carefully, so I hope with the MB-6582 I have done as well. It's there and at at the right pins of the SiD IC's it's giving me the correct voltage. I'm publicly troubleshooting in the forum because I didn't get the right voltages at the PIC sockets. I got those low voltages of 0.30 / 0.27 that I noted in the previous posts instead. If I understand correctly that may be because I'm not measuring them with the right mode on my multimeter. So at the moment I'm guessing that I soldered everything in it's right place (no I'm not that noob, it's the late hours) and if I got the 9V right at J4 I should be fine and the only reason I'm not picking up the 5V at J4 and the PIC sockets is because I'm in the same mode on my multimeter and because I'm measuring them relative to ground? That jibberish aside I'm really grateful for the feedback man and the beer was never meant as a bribe, I just thought it had to be done, so why not!? Cheers! Vlad

Just in case. The C64 PSU i have is a "black brick" type. it outputs : 5VDC 7.5W 9VAC 6.7VA. and after a short game of intl. Karate I can confirm that it's working with my C64 ("breadbox" type).

Ok, with the power switch in "off" position I'm reading J1A 1 0.20 2 5.05 3 GND 4 0.32 I took another reading from the switch, with ground being pin 3 of J1A this time (switch off) S1 1 5.06 2 0 3 0 4 0.30 5 0 6 0 So I assume the PSU is fine unless I should be reading 9v from S1 too. I measured the plug and i'm getting the same 5.06 out of one of the pin's. BTW I have attached a picture of the PSU's plug .The lower two pins ( the ones that are so cosy together) are measuring 5.05V, all other pins give me no V's. Now with the power on it's a different story. J1A 1 4.55 2 0.37 3 GND 4 4.72 J3 0.31 J4 5v- No 0.29 9v-Yes . 8.96 12v- 0 So i guess the problem starts at J4. I have soldered the bridge J71 with a resistor leg (that was before I discovered those neat bridges for sil headers), but it should be alright. the soldering joint is stable. Waiting patiently for a reply, Many thanks, Vlad

Hi guys, I thought it was all goodbut apparently I screwed up somewhere. Here are my readings taken from a red base pcb (from smashTV). The whole pcb is populated with everything apart from the IC's . Don't get me wrong I followed the instructions carefully and assembled the PSU option A. j3-0.57 J25-12.73 output of V1 (c12) -8.94 sid socket's (1- 8) - 8.94 Power switch pins 1-0.56 2-0.56 3-0 4-4.72 5-4.72 6-0 I am getting 4.56 and 4.60 from the top two pins on the C64 PSU (with the plug facing you) I can't find 5v anywhere in the psu section of the pcb and I'm a bit lost here. If I missed some vital information, please let me know. Thanks, V!

Thanks, for the fast reply. This really helped, I have found/ordered almost all of the parts. The only one left is the M3 countersunk head bolt. English is not my first language so I'm a bit challenged in identifying the right components. Could you please confirm if this the right bolt? Other than that I'm done with CS part's sourcing. http://www1.conrad-uk.com Part no.: 521676 - 89 Thanks! Vlad

Thanks, I'm glad you did! I should rename the topic ...I was looking for a white on black display after all. Please bare with me, I'm learning fast. The only DIY project I have completed before this one was the mGB Arduino and that was a snap compared to this stuff. Still the wiki and forum make it really straightforward.. Oh the ramblings...

Hi, I'm in my final stages of construction of the MB-6582, onto the CS. Sourcing the mechanical parts in question appears to be a daunting task and extremely expensive (100 spacers for 35 pounds on ebay!!). Can somebody share any advice on sourcing this stuff in the UK,London area? Thanks!

Ok, so I've nailed down this one called Batron . LCD MODULE, ALPHANUMERIC, 20X4 No. of Digits / Alpha:80 Illumination Colour:White Character Size:4.69mm Supply Voltage:4.6V Display Area Width:76mm Display Area Height:25.2mm Operating Temperature Range:0°C to +50°C SVHC:No SVHC External Depth:14mm External Length / Height:60mm External Width:98mm Background Colour:Black Character Width:2.9mm Connector Type:T, 1 x 16 Display Technology:LCD Font Colour:White No. of Columns:20 No. of Rows:4 Supply Voltage DC:5V dc It's in the Uk so I will save on postage. Can somebody please confirm if this one has a serial interface or not? I can't find it saying that anywhere in the description or datasheet. Thanks! 31779.pdf

Thanks guys! I should have found these myself, somehow they evaded me. Thanks for the fast reply's! I will upload pics once I have finished the project. Cheers! V!

Hi dudes! I may have not been posting, but I read a good part of the forum, in particular threads regarding the midibox sid. Couple of days ago i received my base pcb w/parts and cs psb for the *no praise is good enough* MB-6582. Soldering nice and steady ,it's looking good but I'm struggling to find the right display. See, i have plans to paint the pt-10 case white and I wanted to have the lcd to match. All i found so far are green on black, yellow on black but no white. I came to the conclusion that white characters are somehow technically difficult project on a black lcd, but that's silly, right? Or perhaps there is an invert option on this oneMy link http://www.crystalfontz.com/product/CFA634-TFB-KS Any advice would be appreciated. Hope you're all doing great! V!

On the list for panel and wood case. Now of to Smash's shop for the boards and kit....

I'll be naming mine (when i finally get down on it) the [glow=red,2,300]delySID[/glow], I think it's the dopest name for a sid-synth ;). You could try Sick Sid or Siductive :P.
