ok, i’m trying… 
i have several PIC from old projects which i do not use anymore, and some SIDs.
I also have a built MIDI-thrubox somewhere (1 midi IN, several midi OUT - it’s not a midibox) , now replaced by the GM5x5x5. plus a display (not backlit).
I will trade them for a built MBHP_CORE_STM32, so that maybe i will upgrade the sequencer from 3 to 4 with a small effort. Really, i do not time and willingness do build it from scratch!
I have to offer:
1 SID 6581 R3 taken from a commodore 128
1 SID 6581
1 PIC 18F4628
2 PIC 16F877
1 PIC 18F452
2 PIC 18F4685
1 display, not backlit, should be 20x2
1 softpot, linear, from spectralsymbol, 50 cm long
(i will not use this things anymore!)
the miditrhubox should work, it is like this project:
http://m.bareille.free.fr/midithrubox/midithrubox.htm
(not exacly this).
But it is without power-supply: it was power directly the PC thru the joystick port, but it is not difficult to modify. I have the schematics.
if you may be interested, contact me for the details…
