Of course I am replacing his chips. I'm not giving up either. I'm the nice guy who sifts through 100 chips to find a few good ones so you nice people can have nice SIDs. Anyways, it's true that MSSIAH audio diagnostics only uses a sine wave, this is how the faulty noise waveform slipped by. I asked Wilba about his testing method. Unfortunately I don't have a midibox yet, I'm still waiting for the parts for my first core and SID modules to arrive. In the meantime, I made a song in MSSIAH Sequencer that runs through each waveform on each voice with filter tweaks. After this I found three more that had defective noisewaves. This is frustrating, but not nearly as frustrating as trying to buy a Commodore 64c from ebay these days. Hmmm, what to do with the ones with bad noisewave? I'm thinking I'll build a commodore that's dedicated to bassline, and for the few SIDs I have with defective filters, maybe I'll throw those in a commodore that's dedicated to MSSIAH's Drummer application (does not use filter) Maybe I'll make SID Keychains.... SID jewelry in general, SID BLING! I'm gonna make a four-finger SID ring and punch my supplier in the face with it.

Hello Boys and Girls, Today I received my new shipment of 8580r5 Out of the 50 that came in, 18 have already been sold and shipped. This means there are still 30 available! Cost per SID is $22.50 USD + Shipping. E-Mail DJJonnyJams@yahoo.com to order. (Don't forget to include your PayPal Adress and desired quantity, duh)

Say Hi to your mom.

I LOVE MY REMARKED SIDS!!!!!!! and the cute little Chinese girl who sells them to me...

Thanks. I'm very hapy that I'll be able to use this LCD right now, and it leaves me room to grow!

I've been through the walkthrough/wik/ucapss etc. about the minimum control surface for my midibox sid. So far these are the parts I have ordered per frailn's reccomendations: 1. Core Kit with PIC18F4685, PID ID Header = 0000 0000 0000 0000 - $26.95 2. SID Kit - $15 3. 16 pin Female IDC Connector (for hooking up your LCD) - $.50 4. 16 pin Ribbon Cable (for hooking up your LCD) - $2.50 5. 10 pin Female IDC Connector x 2 (for hooking up your Core module to your SID module) - $1.00 6. 10 pin Ribbon Cable - $2.00 7. 2-Pin Female Connector x 5 - for running power to both modules and maybe for your audio in and out - $3.65 I also ordered 10 of the 10k pots just for the heck. I then proceeded to order an LCD, I saw the part about a 2x20 character lcd being reccomended, then I read that there is also a 4x20 option. I then ordered this: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWNX:IT&item=120429145699 for an extra $2.00 I thought, "why not get the demo board, so I can display vulgar messages while I'm building my box" Then I went back and re-read the part that says 4x20 is for mb-6582 My question is: Can I use this as a 2x20 and just use the top two lines, or do I need to order an actual 2x20? Or, is there a way for my midibox (not mb-6582) to utilize this display in the same way that mb-6582 does? I like the level meter... and one more question while you guys are pasting in links to information I overlooked, is there anything else I'll need to get my first core and SID module going? Thanks ~Jonny Jams

I have thought about that as well. I wasn't completely sure about the wiring. I'll give it a shot on one of my commodores with a single SID. My goal is to drill less holes in my beloved commodores, so I'll still be searching for quad pots, but your wiring instructions were very helpful. Thanks!

Yes, you are absolutely correct. I hooked up my 100k stereo feedback pot as you suggested last night, and it works beautifully. I wish I could find a quad-pot so I could set it up to lower the final output volume as feedback is being applied. Any ideas on a simple circuit that would limit the output so I don't have to turn my mixer down while applying feedback?

Surely there must be a way to convert SID station to use 8580? two caps and a 7809 regulator does the trick in our commodores.

Back to the hardware vs. VST argument. If they're both emulations, I think most would go the more convenient route.

Ok, I read your suggested wiring for feedback pots: "Ground goes to left pin (facing towards pot shaft, pins pointing down). Output goes to right pin (facing towards pot shaft, pins pointing down)." This would be fine with a 500k pot, and really, I feel foolish for not hooking it up that way in the first place, but now I'm using 100k pots to get a more gradual taper from dry to feedback, my guess is that hooking them up your way will make my output quieter since 100k is not enough to kill the input completely. In this case I'm just using a 100k stereo pot, and 1 dpdt mini toggle switch. That is my reccomendation for your commodore.

Yes, they can be purchased at Radioshack in the United States, if you can't find a local supplier, you can order through their website. Sorry it took so long to reply, I haven't been following my old posts. Do a search for 500k pot with push button toggle. "Toggle" is the key word here.

1,000 euros? That seems cheap. Some of the commodore chips have already been cloned. There was some guy on Lemon64 forum who had replacement chips for (I forget what it's called, it's at U17 on a commodore motherboard and they frequently fail and give you rainbow colored characters, CIA maybe?) anyways, he had replacements for that chip, not new original stock, not remarked pulls, but brand spankin' new, recently manufactured chips. Perhaps they were just a modern chip that emulates the CIA, and fits in the socket. If that's the case, manufacturing SIDs in this manner would be of no use to the analog purist musicians whom are seeking these chips. What ever happened with SwinSID? I wanted to buy some of those but it doesn't seem like they're for sale.

This comment was Satire.

Chemistry, no source files? Sounds like magic. Is it like stem cells? Where they take one molecule from a SID and grow new SIDs off of it? :) Wilba, I believe it IS possible to clone SIDs. I don't think anyone who has the resources to do it understands how valuable that would be. Perhaps we should start a company for research and development. If man can clone a sheep, a cow, and a 303, surely we can clone a simple IC chip that is 20 years old! In the meantime, I tested all of the twenty chips I recieved. Only 2 were defective, and the rest performed beautifully. This is a fair enough ratio for me to invest in another 50, which I will have in by the middle of next week. Peace ~J

Whatever, at least I asked first.... You didn't say "NO" :) That's too bad Wilba, I was gonna send you some free SIDs for your endorsement..... (Like you don't have enough) -maybe I will anyways, and yours will be triple-dipped! So, if you don't have a lifetime supply of SIDs like Wilba, and you're sick of bidding on commodores on ebay, and paying to have them shipped, and not even knowing if the chip is good, or if it's even 8580...... some nice people in China have done all the hard work for you. Save yourself the hassle and buy them from me. Yeah they're probably remarked. Big Deal. Think of them as refurbished or something. Like the boss says "You want SIDs? I got SIDs"

Hello, I have found a supplier who has over 100 MOS 8580r5 available. I purchased a lot of 20 to test and I recieved them yesterday. Here are some pictures: Wilba thinks these SIDs have been remarked, and I trust his judgement, but there is really no way for me to know for sure. I tried to strip them of any paint or ink that may have been used to cover-up the old markings, but there was none. I used mineral spirits, laquer thinner, and a few other strippers that we have at the shop, and not even so much as a stain on my cloth. For me, this means they passed the first test. When I got home, I tested the osc and filters and they are all working perfectly. I can't say for sure that they were or were not remarked, but since they are functionally flawless I plan to buy and sell about 100 of them. I would like to offer them to the midibox community for $22.50 + shipping. I'm not competing with Wilba, he "haz no moar SIDs" and has given me permission to sell mine on this forum. Personally I don't care if they're remarked or not. I CAN GARAUNTEE that they ARE genuine 8580r5 and each one will be tested before shipping. If you need SIDs send an e-mail to: djjonnyjams@yahoo.com Your subject line should say something like "I need SIDs" the body of your letter should contain your paypal adress, shipping adress, and desired quantity. I will send you a paypal invoice for your chips, and if I have them in stock, they will ship within one business day of recieving your payment. If I am between orders at the time of your payment, I'll notify you and will ship them within one week. I already tested, packed, and sold the first twenty. I am currently taking orders and will have more ready to ship by next week. I am very happy with my chips, I know you will be too. Thanks ~Jonny Jams

Sure, I'll throw in the ashtray, but the pipe is strictly for tobacco...

I DO ship worldwide..... Maybe I should state that in the listing. Yeah, feedback is great on the 8580's, and probably just as good on 6582, but it's a worthless mod for 6581. I can't wait to get my new 6582's, I'm definitely dropping one in a commodore.

I'm still modding commodores to raise funds for my midibox projects. Finished this one last weekend: Now on Ebay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MESELX:IT&item=200341152795

Anyone in the USA need one of these: http://www.chinavasion.com/product_info.php/pName/headreststand-incar-tft-lcd-monitor-7-inches-black/ they are a very good screen (I have one) and can be had for as little as $32.00, but it costs $25.00 to ship just one, and the per unit price is higher as well. If anyone in the U.S. needs one of these, I'd like to order at least five, possibly 11 to get the biggest price break. Let me know if there is any interest.

Aside from wiring the right components to the right pins on a chip like this, wouldn't you need to write your own code to tell it what to do? Seems daunting, but I'm still in the inital self-doubt phase... Something I'm working on currently is a small circuit that converts -10db to +4db so I can equip my commodores with balanced outputs.

Ankle strap? That's Gnarly, Surfer Dude!

Sadly, I only have one of these. I wish I had two, I would send one to each of you just for being so considerate of eachother. I really like this forum. Just out of curiosity, what are your plans for this chip? Do you intend to build a synth? I had that idea too, but I'm not a computer programmer...... I think this chip's intended purpose is to generate tones for test equipment, could be interesting for music though... Frailn, did you get my PM?

I have two of them. CA3080E
