Or one of these? http://www.dsperado.com/

Will it still be possible with your layout to build and power one Core+SID at a time, or will you need to build all four sets at one time? I am very interested in hearing more if you manage to finish this design. Have you spoken to either of the two board sellers (SmashTV and ..?) about stocking this board if you get it finished? Even the 2x board you mention would be pretty cool.

Sure is, that would make a MacOS X port very easy.

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3871759899 I just noticed these and thought I would put them up for anyone interested in playing around with them. Maybe a substitute for lots of buttons, SID matrix, buttons that change labels... See SmashTV's comments about resistive touchscreens here: http://69.56.171.55/~midibox/forum/index.php?topic=2466.msg16367#msg16367

Unless you make some of them encoders, and use the MIDIbox 64e firmware: MIDIbox64e

http://www.dansdata.com/rup.htm Just sayin'...

Is it possible a dedicated PIC could do service as a DAC, using the existing analog out pins? Perhaps a different (cheaper?) model?

Have you checked out the new DSPics from AD? A DSP and a PIC on one chip, with one code environment. Could be ideal.

If you do a search here for infra-red or IR, you should find a link to some Sharp (?) IR modules that are used for range sensing in robotics work. They come in both analogue voltage-out and digital pulse-out flavours.

Okay, this is just one dreamer's suggestion... Have you seen postings about the PS/2 keyboard/mouse interface for MIOS? Wouldn't it be cool to be able to connect a QWERTY keyboard direct to the Speakjet module, display and edit text on an LCD, then hit "Speak". Using special characters or modifier keys (shift, ctrl, etc) for different phonemes.

Don't MIDI CCs only have 128 values anyway? Yep! DIY Ribbon Controller And the transparency story gets even better... Hooray! Â Touch-screen MIDIboxes!!

if you do a search for palm midi in these forums you'll find some links that I and some others have put up.

AS far as the Gameboy sound goes, you might want to check out nanoloop.de and search for Little Sound DJ (LSDJ). They are both sequencer carts for original Gameboys. Both can do MIDI sync. Nanoloop is a commercial product, but the LSDJ site has instructions for making your own cart and MIDI cable, as well as selling premade carts. For general Gameboy hacking info, try devrs.org . And if you're into chipmusic, have a look at micromusic.net . As the Gameboy side of things is pretty well taken care of by these projects, TK going on his previous posts would probably not want to put any time into a MIOS Gameboy. Correct me if I'm wrong here, Thorsten! On the other hand, it did occur to me that a Gameboy would make a nice display and controller add-on to a MIOS machine... ;D

This is also available for Mac OS X, Linux and various Unixes http://www.ribbonsoft.com/qcad.html

This site http://www.sirpic.com/ has some information and source code on interfacing to PIC projects from a Palm PDA, either via RS232 or infrared. There are also easily made DIY MIDI interfaces for Palms and various software at http://www.crudites.org/soundventures/handheld-music/ - Currently down; here it is via archive.org There are also Java virtual machines for Palm (JSynth on a Palm?) Just a few random thoughts...

Stumbled upon this: http://tomscarff.tripod.com/vibraphone/midi_vibraphone.htm The kit is no longer available, but the schematics etc are still there.

Up to four. Â You can merge and split channels before, between, and after each effect too. Â For example, inputs 1 and 2 going into a stereo pong delay, 3 into a chorus, 4 into a flange, then all of them into a stereo reverb. Â You can dedicate the box's whole processing power to one full-size effect for better quality, or split it amongst any combination of half- and quarter-sized effects. Â It's incredibly flexible. Â I'm amazed they didn't sell better. And with input and output levels and wet/dry mix for each effect assigned to a MIDI controller, you can use it as a 4-input mixer. It's a 1U rack, and only about four inches deep. Â The front panel is fairly clear. Â One of the first MIDIboxen I plan to build is a 1U knob board to sit underneath it. Â I love them. Â Lush, rich and varied. Â No distortions though, and only the Quad Four has compression (along with a vocoder and a 15 second loop sampler). There are three different models, Studio Quad v1 and v2 (can be upgraded) and the Quad Four (no "Studio").

A rack that might work for you is the Digitech Studio Quad, or the later Quad 4 (which I have). It has four ins and four outs, and you can run up to four different effects, with very flexible routing between the ins, the effects, and the outs. You can also assign seven parameters per effect to MIDI controllers. So one of these and a MIDIbox controller would be pretty powerful.

It's very difficult to make a laptop LCD work with a VGA output. They use totally different protocols, voltage levels, all sorts of things. You need to buy a converter board from somewhere like earthlcd, and they cost as much as a cheap desktop LCD.

Very nice. I wonder if it is pitchable?

If you'd like to compare another Wiki documentation project, that evolved without any "bosses", have a look at http://melbourne.wireless.org.au/wiki/?TheEvolvingFAQ

Have you had any thoughts about building a single board for 2 or 4 SIDs?

How about the MIOS128?
