  1. Thanks dude! (loving the grabbag rendition ;)) I'd already checked the stuff on the main page, I just wanted more of an idea of some of the sounds out of the box :)
  2. It's funny that Wire Wrap should come up as a topic- I'm about to make a Z80 based computer an have been looking for wire wrap boards and pins and stuff, but I can't seem to find where to buy it... Anyone have any idea where I can get it from? (I'm based in the UK, so ideally somewhere here, but if not then I'll buy from abroad)
  3. Hey, Is there any chance that anyone could make a quick YouTube video/ sound clip of some of the preset sounds of the MidiBox FM? I'm gonna make one to go along with my MIDIBox SID soon, and I'd just like to hear some sounds to tide me over. Cheers!
  4. Wow, MB Sid is really developing some nice (non-typical) sounds!
  5. Ahh, its mainly for the challenge really. As for the bitmap fonts, I was planning on using the Character rom from the C64. I'm not sure if it can be done without stupid amounts of effort, but I'm hoping that it's possible. Thanks for that link- it looks really interesting. I've been looking at ways to produce videos from micros, be it directly or with a device like the Video Critter, and I figured that the VIC-II was worth a shot as I already had one :) As I say, I'm not sure if I'll be able to get anything working, but if anyone else fancies having a go too, then that'd be cool :)
  6. I've done some digging around and I think I know which chips are needed, but there is a logic chip that sits between the VIC-II and the processor. I think this is for controlling use of the ram (VIC-II has the wheel in this respect- it can stop the processor accessing the ram if it needs access itself), but i'm not sure what I could remove and what I can keep. If I can find out the minimal configuration for using a VIC-II, the programming I believe will not be too difficult, and I think that in bitmap mode, a matrix of the screen is stored in RAM (320x200) so we'd be able to get a relatively high resolution display out of it (only 2 colours can be assigned per 8x8 pixel block though). stryd_one suggested use as a display for the SEQ, which I think is a brilliant idea, as a seperate display module could be made and linked to the core, and a cheap colour screen (like the ones for the psone which are about £20) It'd be cool if some of you could maybe have a look at this issue yourself, as I'm not sure that I'm experienced enough on the hardware front to pull this off (i'll definitely give it my best shot though ;)) I think that this could be a valuable addition to the MIDIBox lineup, and It'll save waste too- how many of us already have a load of SIDless C64s sitting around? ;) Okay... enough rambling :D
  7. Hey, I've been wondering for a while how easy it would be to use the VIC-II chip with a microcontroller to produce video. Now we already use the SID seperately, how hard do you think it might be to use the VIC-II? I think it'd be cool to be able to produce a little PIC/AVR video games system using the VIC-II (since most of us are in ample supply after killing C64s for Midibox SIDs :P) Am I just crazy, or is this doable...? I found some info on the chip: http://highgate.comm.sfu.ca/~rcini/classiccmp/pdf/ds_6567.pdf http://unusedino.de/ec64/technical/misc/vic656x/vic656x.html
  8. At the moment I've just got the parts sitting in an Amiga power supply box (the plastic one). It all fits real well, but i feel that maybe a nice metal box will be better? I aim to upgrade to the 4 SID CS solution soon though, as I'd Like to mount it in a rack box. I'd also like to build a MIDIBox FM, but i've not been able to come across any cards with the right chip in as of yet (Ebay or otherwise). But it's definitely on the cards. I'd also like to see if it'd be possible to build my own SINE OSC and control it via the CV outs, cos I feel that the addition of a sine would make a lot more nice sounds... not sure if this is possible or not or if anyone has already done it...
  9. Hey Guys, I've just finished building my MIDIBox SID and I'm loving it. I'm thinking of building it into an Amiga power supply box (I've only got Step A control surface at the moment until I can afford to build the full one) I can only say that it has given me the taste for more! I want to build an FM and SEQ now... Maybe after the summer ;) I'd just like to say that the tutorials and walkthroughs posted up are top notch, thanks guys. Anyway, maybe I'll post up some pictures when I'm done with the case?
