Count me in for a full kit. PCB + Base + CS + anything else.

the one thing that wouldn't work for me was the SID crystal. try removing the crystal on the SID chip and wiring core ic:17 to sid ic:6 that's what worked for me....

i don't see anything about a negavite contrast voltage. oh well, i guess i'll start over and re-wire the whole thing, maybe i missed something, or there's a bad line or something.

ok, just got a new lcd screen (http://www.allelectronics.com/cgi-bin/category.cgi?category=365&item=LCD-97&type=store) i've wired it up and so far i get: backlight + 5v running throughout, but nothing on the screen. i've checked my connections, re-uploaded MIOS and apps, re-wired a few things, and still have nothing. one thing that worries me is that nowhere in the datasheet does it say HD44780 compliant. i'm wondering what i should look for next?

i just picked up a TI little maestro toy with the intent of bending it. i'm looking for some good information on circut bending now. any tips or links?

sid emulator plugins for mac? tell us more.

i'm wondering what the approximate size of a full CS Sid is for the purpose of building a rack mount unit. i'm thinking about 3U? can anyone confirm or deny this?

sounds easy enough. should i put caps around each regulator? like this: input>2200uF>7812>2200uF>7809>100uF>output or something like that? i need to read up on caps and whatnot....

i just ordered these guys: http://www.allelectronics.com/cgi-bin/category.cgi?category=310&item=KNB-126&type=store http://www.allelectronics.com/cgi-bin/category.cgi?category=310&item=KNB-164&type=store

i just got a 16v PSU to power my SID. i'm worried about over-heating the core voltage regulator by sending 16v straight into it, so i want to build a sort of "step-down" module. my question is, is this simple enough that i can stick a 7809 regulator between the main power in and the core or do i need caps in there as well? thank you. -joey

a quick question: when i play my sid, i can hear, very faintly, the note that was just played after it was released. it will change with whatever note i play. is this normal? i know the SID is supposed to be noisy, but i thought it was just supposed to be a low hum. my sid is setup with the clock running from the core module.

ah thank you! the on/off switch is supposed to light up, but i can't get it to work. no worries though. i like that i was able to fit it into such a compact and small box, but i want to add a basic control surface, but i don't think i could fit it all in there. well, maybe, but it will be a tight fit.

well, i still have a few things to add (i forgot to drill holes for midi i/o :-X) and a bug or two to work out, but for now, this is my finished SID. i took a good picture last night, so i figured i would share it with the community: this guy is going to end up being one of those things that i never finish because i'm always adding or changing something on it. i plan on eventually, making a rack-type unit, but money won't allow it right now.

so right now, i'm powering my SID with two 9v batteries, and the core is running on a 9V PSU. since i can't find any solutions for a PSU at the moment (no money either), i want to build a small circut to power both SID and Core with my 2x9v set up. if it wasn't running at 18v, i would just make some connections to split the supply line straight to the SID and core, but i'm worried about the heat coming from the core regulator. in order to help with this, i'm thinking that building a mini-psu type thing for the 18v to go into, then straight out to the SID, but between the batteries and the core would be a 9v regulator. would this work and be a good idea?

TK! you we're right!! it's works!! honestly, i jumped when sound came out. it's the most beautiful thing ever. thank you for all your hard work on this and the other projects! i still have a few bugs to work out (note sounds after it is played) and the CS design, but THANK YOU!!

ah, great idea. i'm using smash's board that included the 1.000MHZ oscillator. it is possible that this guy could have been damaged by heat? i'm going to try running the clock off the core module and see what happens here. just so i have this straight i wire it from core j7:3 to the sid clock input (pin 6), correct? do i need to wire anything else?

yeah, MIOS seems to be loaded correctly. i was able to run the MBSID_interconnect_test and it checked out, so i can only assume that MIOS loaded correctly. it's ok though, it was a crappy LCD to begin with and it crapped out on me. i saw one on allelectronics.com that i liked. seems like it runs in 8-bit, so no need to edit the program (which i can't figure out how to do anyway).

hmm. i'm using smash's boards, and from what i can tell, everything is on there correctly. i went ahead a rebuilt the entire audio out/in section and still got nothing. here are some pics of that section: (part side) http://i2.photobucket.com/albums/y17/iamlark/C64/SIDpics015.jpg (solder side) http://i2.photobucket.com/albums/y17/iamlark/C64/SIDpics016.jpg i can't see anything wrong, but maybe i'm missing something..... i checked the voltage on from SID IC:28 to 14 and it's reading at 12.3v. would that be enough to blow the chip? if not, what would be the next step? new module or new chip?

yes, do try MIOS Studio. i found it to be a much easier interface to use. don't forget to route your midi connections. i always forget to do that..... edit FYI: i've been using MIOS Studio on a PC, but i've been having some problems with it on my ibook. it's not recognizing my interface (M-Audio 1x1). the computer recognizes it, but MS doesn't.

the data sheet said it's 4-bit and to use db4-7. i'll give 0-3 a try. thanks!! update: 0-3 gave me nothing. for a while, i was still getting the row of characters (when hooked to 4-7), but then the stupid thing crapped out on me. i'm about to throw this whole project through the window with the amount of problems i've had :'(

yeah, no joke. right now, i am clueless and i am begging for help. (i probably should get a better LCD, but i can't afford it right now) here are the schematics for the lcd1022: http://www.bgmicro.com/pdf/2x16el.pdf i have connected everything as it says on the bottom page 4 with the exception of B+,B- (this lcd needs EL inverter, which i haven't build yet)(would this matter????). so, B+,B- and DB0-4 are hanging free. ho-hum....

so, i'm not sure what's wrong at this point. my core checks out good in MS. i ran the MBSID interconnect test and everything checked good. i loaded SID main, then SID_6581_without_cs, but then nothing.... i blew my c64 PSU, so i can't check the SID chip with the C64 (i don't have any games anyway). i'm not sure if i have the audio hooked up correctly though. right now my core is powered by a 9V PSU, and the SID is powered by 2*9V batteries. i've hooked the audio out to SID J3, and only got some pops as i made the connections. then i tried sid J3:1 and core J2:2 and got nothing (like in http://www.ucapps.de/mbhp/mbhp_sid_c64_psu.pdf). then i tried sid j3:1 to sid gnd, still no noise what so ever. not even a buzz. the only thing i haven't tried yet is stuff it with my back up sid, but i want to make sure that i have my connections right before i do that. am i uploading my apps in the right order, and how do i connect my audio out with this setup (or a set up using one wal-wart PSU)? thank you. edit: i stuffed the module with the backup SID and still got just about nothing. the only difference this time is that i would get a low buzz if i touched the chip or the caps. the audio out was hooked to J3:1&2. once i had the buzz, i tried using the keyboard interface in MS, but got no real noise.

so i'm having lcd problems. mios studio says that my core is good (hooray!). when i connected my lcd, all on got on the screen was a row (top) of black boxes for a second, then nothing. i'm using the 20x2 lcd1022 from bgmicro and checking the datasheet, i believe that i have everything wired correctly. from the data sheet, it says that it uses db4-db7 for 4-bit operation. i'm not quite sure how the lcd debug in mios studio works, but i sent a message to it, and once again got the row of black characters that disappeared after a second. any ideas on what could be going wrong?

wow. i wish i would have known that earlier. i just put in an order to BG Mirco right before the PSU blew. i'm running off of a couple of wall-warts right now, but i think in my final design, i might use a computer PSU, or something similar. i picked up an LCD with an EL backlight and it needs -5v. i figure those PSUs will give me that and +5v, +12v. although, i just read something about computer PSU (switching type) are not good because they will create a lot of noise or something along those lines. we'll see. that's way off. i have to get everything running first.
