no, the DOUT isn't necessary but that's up to you i guess (LED's etc.). either way, the C64 PSU is used. i'm not sure what you are asking. the C64 PSU gives you both 12V/9V and 5V rails and the optimized PSU "optimizes" it's efficiency. better signal to noise ratio etc. otherwise, you will have to find a separate PSU for your Core module and a separate one for your SID(s) module(s) not to mention that you may not get as clean a sound with whatever you decide to use. i'm still not sure what you mean about the whole cannibalizing of the C64...?

you may want to look into a DOUT kit as well... as far as MIDI jacks, you won't be able to send and receive MIDI if you don't have a way to get it into and out of the box. ;) also, the C64 PSU is external not internal so "cannibalizing" isn't necessary BUT it is necessary, if you have a C64, to take the SID out of it as the "SID Kit" from SmashTV doesn't come with a SID.

thanks neb! i'll be back with fuse questions later. going to buy that transformer!

hey guys, this shop is right down the road from my house and i thought i might give this transformer a shot. i am pretty intimidated by the PSU part of this build. :-[ anyhow, will this transformer work? thanks. [edit] looking at the pictures, i'd probably actually want this one...?

i didn't. it's pretend.

it may not hurt to actually build one of the finished boxes first i.e. MBSID. that way you know what you are getting into and you'll understand all the work that goes into these things, AND it'll keep you busy for a while instead of waiting for unfinished projects to get done. also, try to stay away from "ancy," it causes unexpected potties...

what!?!?! crap. now i have to build my POKEY boards all over again. :(

WOW!! ;D :o that's absolutely brilliant! i saw your post over at 8bitcollective. very cool man! i'm jealous you know someone that's an animator!

oh guiseppi, you're always coming to my rescue!! ;D if this works, it will solve my problem with finding PSU's for the MBAY and FM! i don't have an amiga and i sure as hell wouldn't retire it if i did but i'm sure i can find PSU's somewhere... would this PSU be the A500/1200 variety?

that's great! ;D i just need to find a PSU for this and my MBFM... :'( i have the boards and such done i am just having a serious problem figuring out the PSU situation. the same PSU would work for both wouldn't they?

that would make the most sense seeing as you only have one core in an MBFM. ;D [edit] also, you may want to go with an 18f4685 (as i've learned) for future expansions in the firmware. just a thought. ;)

i actually haven't even tried to edit any of the patches yet! what are you using for an editor? i don't believe mine came with a sysex program for doing such a thing... :'( any chance i could get a copy of that? anyway, sorry for derailing the thread, great job on the MBSID!

great work! ;D also, how do you like the FB-01? i love mine! nothing like MIDI/FM goodness. it has a different sound to the OPL3 but they mix well.

no need for pics. ;D i just wanted to know if you had actually purchase one, you know, to see if they were reliable/worth the effort. thanks for the reply! :D

right under your nosea small amplifier circuit has been added since that parts list but if you look at the recent schematics you'll be able to find the missing parts. ;)

heya fräulein, did you ever get around to buying one of those Condor PSU's? i've got a MBFM waiting for a psu... just curious if it worked out or not. ;) (anyone can answer, not just fräulein.)

oh nILS, always one step ahead of the game! ;D....

the problem with that is this: POKEY register table 16 pokey registers - $D200–$D20F Register Write Read Name Description Name Description $D200 AUDF1 channel 1 frequency POT0 potentiometer 0 $D201 AUDC1 channel 1 generator POT1 potentiometer 1 $D202 AUDF2 channel 2 frequency POT2 potentiometer 2 $D203 AUDC2 channel 2 generator POT3 potentiometer 3 $D204 AUDF3 channel 3 frequency POT4 potentiometer 4 $D205 AUDC3 channel 3 generator POT5 potentiometer 5 $D206 AUDF4 channel 4 frequency POT6 potentiometer 6 $D207 AUDC4 channel 4 generator POT7 potentiometer 7 $D208 AUDCTL control over audio channels POTSTAT read of all 8 potentiometers port lines $D209 STIMER timer start KBCODE last pressed key code $D20A SKRES serial port status reset RANDOM random number generator value $D20B POTGO start port scanning sequence $D20C $D20D SEROUT serial port output register SERIN serial port input register $D20E IRQEN IRQ interrupts activation IRQSTAT IRQ interrupts status $D20F SKCTL control over serial port SKSTAT serial port status the same bit registers used for audio are also used for the potentiometers... i.e. can't use both at the same time but possibly one after the other.... either way, there would have to be a processor that translated all this, including the keyboard (qwerty not musical) key presses, running along side the micro controller already in place with the MIOS app for the handling of the POKEY. basically, if you want to go the route you are speaking of, you might as well get and atari 8 bit computer and a tracker... sorry to be a downer. :'( [edit] for poor chart alignment. ;D

is this the calliope that was made using hair driers? i remember this but it may be a while 'til i can find the link... :-\

there's a reason for this... :-X you may want to build an MBFM first. that may change your mind about the APU. ;D

PT-10 plus Panels sounds great!! ;D

got 'em!! ;D

i'm all for this man!! i'd love to see a documentary on the SID and Bob Yannes and even the technology that was out at the same time in competition for various micro-computers etc... keep us posted!

it's great! you can watch it here. although, the SID only really does get "mentioned" and there is no background on the SID. it's more like a name drop.

yes! much clearer! i just didn't want to misinform the O.P. ;D
