Unfortunately I've come that point in my life where I've realized my desire to build stuff was greater than my desire to use it, so I'm selling some stuff to get other stuff that I can actually use.

 

I'll post some exterior pics soon but here's the list

 

MB6582

- All blue LEDs

- White Waldorf knobs

- Blue/White LCD screen 

- LCD window

- Stock panels with blue inlayed line dividers / white text

- Setup with 4 cores

- 2 6581s (working) - CORE 1

- 2 8580s (working - see known issues below) - CORE 2

- US PSU pulled from a C64

- PC Fan

Known issues

- all 4 cores have been tested to work but the first core can't communicate with core 2.  Its likely a simple resistor problem, but I never got around to actually correcting it.  So Core 2 wont actually play just yet.  Once that issue is worked out, you can slave cores 2-4 Cores 1,3&4 work great. Core 2 appears to have a problem with RX communication.  TX works fine, needs a new PIC with ID:1. RX is likely a physical connection issue.

$600 US + shipping

I'm going to move the 8580s to core 3 and make sure everything is working.  I couldn't get core 2 to work with a new PIC but the other cores are communicating well.  

So with the fix, I'm dropping the price $525 US + shipping.  

Also 

I have a GM5x5x5 board with a spare GM5 chip. This is not a kit, just the PCB and GM5 chip unsoldered. $30 + shipping. [Reserved, pending sale]

Known issues

- the mix potentiometers are not installed, I bought the wrong ones but if you're a kit builder, this is a 30 minute job or less to add on.  The headers all already installed

- all 4 cores have been tested to work but the first core can't communicate with the other cores.  Its likely a simple resistor problem, but I never got around to actually correcting it.  So Core 2 wont actually play just yet.  Once that issue is worked out, you can slave cores 2-4

 

It's still incredibly functional which is why I never got to the other core. 

 

$650 US + shipping

 

Also 

I have a GM5x5x5 board with a spare GM5 chip. This is not a kit, just the PCB and GM5 chip unsoldered. $30 + shipping. [Reserved, pending sale]

 

If sale of  GM5x5x5 board with a spare GM5 somehow fail. Let me know. I will buy it.

This particular sale will probably be closed out in the next day or so.  I have a solid buyer, i just need to get to the post office. 

 

That said, I have 1 more GM5x5x5 and 2 more GM5 ics. I may consider posting them for sale since my audio interfaces do the work of this tool anyway. I'll consider it...

Some pictures of me playing around 2 days ago.  At this point, short of Core2 it's a fully functioning MB6582.  The last 2 cores (3 & 4) have the SID caps left out so that you can either socket them for modularity or configure it yourself.  There are no sids populated in 3 & 4 per the original pics above.
