http://kevtris.org/Projects/sid/remarked_sids.html well, I wonder if someone have made such experience with "old new stock" chips ? may it's a common 6581 problem with dead voices and filters, but what about a faked print on the chip? quiet a bit much work to fake such a chip just to sell it as "new"...

just seen some videos about the tenori-on on youtube ... would be really crazy to have a MB-SEQ with a 16 x 16 LED button UI 8)

well, I have read a lot of threads about PWM and stepper motors and so on, but I couldnt find an final answer that helps me to answer my next question. I like to control some RC servos with the MB64. That means the DOUT have to output an PWM signal. I'ts not really highspeed clocked ... every 20ms a pulse of 1ms (min. value) to 2 ms (max.value). I have read that PWM needs very much performance, but I dont know if this relative slow PWM is also too much for an PIC (in the case that there are 4 to 16 such PWM needet). And finaly I have no idea how I could programm such a PWM "option" ::). someone tried this ? any hints ? Thanks e-toy

Most printers wont work if you only disconnect the fuser power. There's an thermal sensor wich controls the heat and if the heat dont come, the printer will report an error. If you can hack the sensor control, it will work.

Thanks for all your tips ! If I understand right, I could attach an RS-485/422 line driver directly to the MIDI Ports to transmit MIDI over longer distance. There are no special Driver needet. right ? The RS-485 multi-point feature sound very nice :) Do I have to use a full duplex line (2 Twisted pair) or does it work also work with half duplex ? I will try to explane what project I'm working on. May it help ;) I need to control some Simple I/O's distributed on an wide space (outdoor). The I/O should have 16 Outputs and 16 Inputs. Every Output switch an Relais. The Input monitors the Output load (is a consumer e.g. lamp, attached proper to the Relais or not) and make it visible with an LED on the I/O. Every I/O should be adressed separatly (may I could use MIDI channels for a max of 15 I/O's). I would use one Core and 4DOUT + 2DIN Module for One I/O I also need a "Remote Control" to switch these Output's on an off. Normal state should be off, after trigger the Output, it should go in ON state (for 10 - 100 ms). The Output load state should be visible also on the "Remote Control". For the "remote control" I would use one core and x DIN/DOUT modules (depends on how much Buttons/Leds would be implemented. I think the MB64 SW could also be usable insted of the MIDIO128 because (if it works) I may also would try to implement AIN on the "Remote Control" and AOUT on the I/O Module. So i think the only problem is to transmit the MIDI data over long distance. I know, my english is not very perfect, but I hope you understand what I try to explane. e-toy

ok thanks for your infos TK I think I'm not the dedicated freak to solve the Can implementation ::) what about RS422 ? Do you mean instead of the MAX232 an other driver or an RS232 to RS422 converter ? The only problem with RS232/422 is (as far as i know) the unicast. So I can only connect two devices together ??? And of course the cables (two twisted pairs for RS422) hmm I'm a bit confused e-toy

quiet expensive (over 400 bucks) for one pair, or ceaper boxes dont reach enought distance ... maybe theres a good cheap box, but I could't found it. May there's a much cheaper solution ::) what about max distance for DIN/DOUT Signals ?

have found some answers Yes Two wire solution (differential)

hi there I'm on an project for an MIDIO 128 like controller, but I need very long distances between DIN and DOUT (up to 200 meters total) . As I know that the new PIC 18F4685 use an ECAN Bus for linking to slave core Modules and this ECAN are capable to transport Data over long Distances( 40 meters @ 1Mb/sec), I asked myself if I also could use such a PIC for MIDIO 128. Well, I didnt found an answer :( so I try it here ;) My idea is to use a Master Unit Controller wich I can select the Slave Modules and trig the DOUT of the selected Slave Module. In addition I use an MIDI I/O to control every DOUT of every attached slave in realtime. The Slave Modules would be linked with Master over the CAN Bus (long distance) As I'm not an expert in MIOS and C programming (in fact currently I'm an beginner) I have a few questions 1. I think MIOS 1.9 is ported to PIC18F4685 and CAN BUS is accesible. Is MIDIO128 also usable on this PIC and can access to the CAN Bus also ? Is MIDIO128 suitable for my project ? Better ways ? 2. Is it possible in MIOS to reduce the Can Bus speed so i can use longer wires (distance to Slave) ? Do I need extra CAN tranceivers ? 3. In MBSID CAN it's a onewire solution. What is needet for longer distance ? The slave Modules are Battery Powered. Is a common ground imortant ? May someone can give me a hint ? Thanks in advance e-toy Have made a picture for better visualisation

ok I found it ;) sorry for wasting time ::) for all others who couldn't found it http://www.midibox.org/forum/index.php?topic=9461.0

me too

go ahead and try ;) for me graphics arn't really important, as I only need it for music purpose. But you could easy make a simple hack to toggle between Gaming tune and Music tune. Just use two pots an a switch to toggle between the two different values. Or even easier. Buy an NTSC Console! (and hope that your'e TV is able to display NTSC Video) If someone knows an other working hack that alter the tune of sound without change the video frequency, let me know ;)

hey Martin_Dubka let me guess You are using a MIDINES in an European NES Console right ;) look at here http://www.midibox.org/forum/index.php?topic=4555.30

vielleicht ein zu klein dimensioniertes Netzteil ? ::)

i had to reopen my NES to make a picture With the pot on PIN 3 of LT1799 you can adjust the CPU clock frequency (tune) right tune will be at arround 3,8K so you can use a 5k or 10k pot. cables should be as short as possible. CPU clock frequency is about 28 Mhz. Note that you wont get a picture out of the console anymore because the GPU will also be "tuned" and TV cant sync anymore to this frequency. greets e-toy
