No, you need 2 cables for MIOS studio to communicate with the Sammich.

If you are using 6581 SIDs then you need a regulated 12Volt supply or you will fry the SIDs. For 6582 and 8580 SIDs, these use the 9Volt regulator IC4 so any anything upto about 15Volt will be fine, just make sure the jumpers are in the right place. The echo power supply you have is not a regulated one which is why it gives 19Volt with no load on it. Hope that helps. Tim.

Sorry, didn't quite understand the problem. I think this post will help: The debug board needs to be separated from the LPC board. You do not have to cut the debug board off but you will need to cut the tracks between the 2 rows of header holes. I hope that solves it. Tim

Have you tried the LPC on its own (not connected to core PCB)? This is what Dmesg shows on my Ubuntu machine for the debug board: [ 368.584139] usb 1-2: new full speed USB device using ohci_hcd and address 3 [ 368.790167] usb 1-2: configuration #1 chosen from 1 choice lsusb shows : Bus 001 Device 003: ID 0471:df55 Philips I couldn't get eclipse to work on my machine as it's a rather old Toshiba but, once the bootloader was installed (using a windows machine) Mios Studio works ok. Tim. PS I think you have to program the bootloader via the debug port before the usb on the core PCB works.

Thanks Tim, I really appreciate that. Regards Tim PS you are not talking to yourself ;)

It is no big deal really, I can wait a while as I have a functioning (most of the time) sequencer with a cobbled together control surface. I guess someone over wrote my entry by mistake. Tim

I added my name to the list back in June, thought I would look to see where I was in respect to the end of the queue. Suprise! someone had removed my name. So back of the queue for me again!

My experience of running the UK order was overall a positive one. The thing to bear in mind is the shipping costs. It's fine if you are shipping inside the UK but for outside the UK it was rather expensive. If you need any advice you can PM me. Tim

That is the exactly what I meant to say.

Is this another way to go left and right? Or will it replace the Scroll function? I think it would be good to have a left right function on the datawheel. It frees up a couple of buttons on the front panel. Tk, thanks for the excellent work. Regards Tim

I use heatshrink on all mains voltage connections (240Volt 50Hz). Just make sure it is rated to 300V and is thick enough not to split when shrunk. Avoid leaving loose strands and sharp points to prevent damage to the heatshrink. Most important, if you are unsure, ask someone who knows about high voltage work. Tim

I am looking forward to one of these for christmas :smile:

One sold. One possibly sold.

BOTH CASES SOLD Hi, I am selling 2 black cases left over from the SEQ V4 bulk order. Details of the case are These cases do not include the front panel and the rear panel is blank. They are £65 each + shipping + paypal fees if applicable. I can ship anywhere at cost. Outside of the EU you will be responsible for all taxes / duty payable. PM me if you want one. Tim.

Check this page http://www.midibox-shop.com/info.html to make sure you have the components mounted in the correct places. There is also a parts list for each module. The holes in the middle may be for the SIL resistor modules, see the link above. Tim.

These serial switch boxes are so cheap, I would buy one just for the switch.

These switches are multi-pole rotary switches. It is a standard data switch, they are also available in 25 pin versions too. Tim

Bad solder joint or swapped wiring on the LCD. Also happens on some displays if they do not exactly conform to the correct spec.

Thanks for the reply TK, on re-reading my post it looks like I was complaining, not the case. It did make me wonder if had done something stupid though. The new version works great and I am loving the new bootloader too. Tim.

Hi, just downloaded the latest version of MIOS Studio and the nice icon is not showing up on the .exe file. I have tried searching for it but the .exe doesn't appear to contain the icon. Machine is running XP Pro and I know how to change the icon on a shortcut. Tim.

Thanks TK, looking forward to receiving it. Tim..

the cathode is the more negative end of the diode. If the output is for example +5volt then the cathode faces out or if the output is 0volt then the cathode faces in. In effect the arrow of the diode symbol points to the lowest voltage point. Exception is Zener diodes, they face the other way around. Glad you got the SID boards working. I had not seen the page in the Wiki before so I will bookmark that one. Tim.

If it is any help, the shift registers on the SID boards are the same as DOUT boards so the interconnection between them follows the same wiring scheme. The only exception is the SID2 connection to J14 on the core, which you have already. Actually just realised that is not quite correct, the 595s form 2xDOUT in parallel. I designed my own PCB with both SIDs and 4 74hc595s (just to keep things neat). I can post the eagle files if you want but they are tailored for my own needs and may prove more confusing. Have you tried swapping the SID boards around? Do you have the PWM signal connected on pin17 of the PIC to J10 and SID J2? Have you set up the firmware correctly (setup_6581.asm etc)? Tim.

I have 2 stereo SID boards with different types of BC547, different manufacturers that is ( I didn't have enough in my parts bin to make them all the same ). The levels are radically different between the 2 boards. The alternative may be to try different transistors rather than an opamp.
