Hi / hello, hope you're all well.... I've been lurking around this group for a few months, reading the occasional message and slowly awaiting the time when I...
Hi David, It should run fine off that power supply. The chip in the circuit can handle up to 15V so the 505 should be ok. Just one thing regarding the CV input...
Thanks for the reply Graham, for some reason I thought that the schematic stated 5volts. I can see now that it does clearly says 9 volts... so no problems...
Hi david, You may have actually seen a schematic of the circuit somewhere with 5V labelled on it. But the components are rated to take up to 15V, so long as...
... David, the caps you purchased will be fine. As the (self-appointed) official electronics engineer of this fun bunch, I am pleasantly surprised to say that...
Just a quick question prior to bending my sk-5 - I remember reading something a while ago, can't remember where. . basically it was related to a point on the...
Anybody tried this? I got it to load my own samples from the ROM. I don't have an EPROM burner at the moment but that is all you would need to make it...
Hey, I was wondering if you can load besides an EPRPOM, could you load a digital recorder (I.E., samsung or RCA recorder), I think that it would be easy as...
I don't think it would be possible to do that. The data formats are totally incompatible for one thing. The ROM chip it uses is a standard 28-pin 27C256, with...
Very cool! I always knew this should be possible. I did the same thing with an HR-16 drum machine: http://burnkit2600.com/gear/hr-16-diy-sound-roms/ I talked...
Dave- I think it's the SK-1 you're thinking of. The one-key play. -justin = burnkit2600.com = ... basically it was related to a point on the unit where a pulse...
The cool thing is that none of the program data running the microprocessor seems to be stored in the mask ROM on there, only the sample and loop/envelope data....
Yeah, stormscorner Jesse. He's also working on a program for writing custom sample roms for the HR-16/HR-16B. Another guy who goes by the name of GordonJCP has...
Has anyone seen what this guy has been doing? http://www.circuitbenders.co.uk/forum/index.php/topic,651.0.html Amongst his stuff, one of the things he was to...
So my friend gave this to me because he said it was broken. I put some batteries in it and found it worked alright except it put some garbled glitchy noise at...
Hi, I need a little help regarding Graham's VCF - I've been a little foolish and soldered the components onto my stripboard without cutting the track on the...
Hi Dave, yes, that's correct - the 470pf capacitor is soldered to PIN 1 of the IC. I've made a little notch in the top corner of the board layout and also the...
Try and get the sampling working properly first. If you can't get the stock machine to sample properly, it may not sample properly with the expansion either,...
I just realized you're the same dude from the mmt8 board, awesome. I dismantled the sk1 and found it to be clean. I'm pretty sure my buddy has owned it since...
In that case, the RAM chip may have gone bad, its kind of hard to know, several things can give the same symtoms as that. But it would be where I would start....
Hello, Long time lurker here, sup everybody. I've been reading all the amazing mods posted here for a while now, though I havent tried any of them yet (other...
Have an SK-5 with two broken black keys. Not even going to bother trying through official Casio routes at this stage, so am wondering if: a) anyone's currently...
I have an SK-1 as is up on ebay currently... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MESELX:IT&item=120309450035 ... From: r.p.b....
Hi Matt, I have 2 songs I'm working on that are almost completely done on my modded SK-8. It's really hard to get around to actually writing songs when you...
Nice, Im looking forward to hearing them. I know what you mean about projects getting in the way of song writing, believe me. Sometimes I work on something...
If anyone is looking for the Casiology webpage, which housed hundreds and hundreds of Casio user and service manuals, including the SK1 SK5 and SK8 service...
... and hundreds of Casio user and service manuals, including the SK1 SK5 and SK8 service manuals, alas, it is no more!! ... Yes, I noticed it too. Actually...
