Oh?!?! OK thanks Pete, I had an LCD in my mouser cart, but my GURU engineering buddy who I bought these PCBs off of suggested the OLED display as it looks quite sexy. I'll search the threads like you say. I don't want to make this any harder for myself than needed. I'm good at soldering and understanding basic analog stuff, but as soon as it gets into digital world I feel quite lost, so I'm hoping that this project helps me understand much better. Thanks for always getting back, you must be an addict here I like am on Muff's chat at ya later

Oh forgot to send the pic, here is it sorry for my shitty iphone pic! So if it is an 8 bit display, is that some cool upgrade or or downgrade. I'm looking at this massive wall that is supposed to be a learning curve hahahahahah I am planning on using this as display, looks prety sexy, just curious if there is some way better option or am I wasting time thinkin about it. :rolleyes: http://ca.mouser.com/Search/ProductDetail.aspx?R=NHD-0420DZW-AB5virtualkey66010000virtualkey763-NHD-0420DZW-AB5 ---Crap. can't figure out how to UL and image--- OMG I feel really stupid right now. Gotta get back to work, I'll figure it out later.

I havent done that chip specifically, but I use a desoldering tool from Hakko, it's the 808 (how could anything called an 808 be bad!!!!!) Its a great tool, you will wish you never bothered with Desolder Braids, or little pumps etc..... I think it is about $200, but if you can get yourself $50 chips with it, it will be paid off in no time. I originally got it to salvage all the compnents off a battery etched Poly6 PCB. You will never go back!!!!! Only other good option is a whole desolder station, but they can be expensive for a good one.

WICKED thanks Peter. No thier Ait's Vias, I'll take a pic and post it when I'm back home, they are little square pads that have a small trace running between them. Like little 0603 or 0805, not very big at all? I thought it might be some cap or something that filters out nosie or something. Anyway, it sounds as if I am looking TOOOOO HARD at stuff, but nothing worse than having everything to build, except a few tiny parts that total $1, but are $20 in shipping to get it to you!!!!!!!!! Cant wait to build this!!!!!

Hey I am collecting all the little bits left that I need to build my 6582 pcbs, its all coming together nicely. I was looking at the PCB in detail last night and I noticed a few spots that look like places for SMD comonsnts to be soldered on, on the underside of the base PCB, maybe for a cap or resister? I have seen no mention of SMD compnents but as I'm about to place my big mouser order for the components I need, I figure I would find out if I need any for those spaces? OOOhhhhh, does anyone have a mouser part number for the expander port? I think it is a j45 d-sub thingy but have never actully sourced one of those before. Cheers, Baggins

Cool so basicaly I install both a 9v Reg and a 12V reg in appropriate spots, then solder a header in the appropriate are for each core (were there is a space for a 3 pin header and the center pin powers chip and either side is a 9v or 12v on silkscreen) and use a jumper thinngy to choose proper rail voltage for each core!?!?!? This is cool becasue I can always move chips around to different cores in future!!!!! Thanks so much, excited this will start soon!

Wicked! Thanks lmp! I have the large base board that has all cores on it. I have been reading through documentation but havnt seen or missed the part about usin jumpers to choose what the rail voltage is for each individule sid core. That's great news!!!! I'll go and try to find instruction in the build doc. I had seen information about what jumpers to use I the section discussing power supply options (a or b etc...) but hadn't seen any mention of using different voltages to individule cores. Cheers, mr. baggins

Hi I am a beewbie here. I have acquired a pcb set and 4 SIDs (6581)s and reading through piles of documentation. Wow!!!!!! Soooo as I gather all the parts I need and plan out this build I am thinking about having two cores be filled with 6581's and the other two with 6582 (or the 8580 other steves the equiventl one is called). Since the 81's need 12v and the 82's need 9v I was wondering if it possible to do this. It is an easy "placement of proper components into certain spots" or would i have to cut some traces and supply the 82's from a perfboard regulator kinda thjng and kludge the crap out if the board. OR IS IT JUST A STUPID IDEA ALL TOGETHER!?!?! Thanks.
