Custom Modified Commodore 64 for MSSIAH & Prophet64

designed especially to run the prophet64 / MSSIAH TB-303 emulator,
monosynth, Drum machine & sequencer



+ 4 analogue controllers with on/off switch for each port
+ Contains 8580 SID chip (not stereo, so can be used as a normal C64)
+ Cut down case to maximise desk space! + Mean front grill for increased cooling. + Beige paint job. Just like an old-school breadbin! + Audio out by 1 x 1/4" mono jack (happy to include RCA adapter for free if reqd)
+ Audio in by 1x 1/4" mono jack + Standard A/V out - for use with a normal C64 DIN A/V cable. + Custom underside label Serial # 001 - with machine name of your choice!
+ days of work put into it!


- The unit is standard 3-channel C-64 mono with a 1/4" jack output,
so if using it for audio you can add your own post processing via effects pedals or in a DAW
+ Audio input is disabled (grounded) to reduce noise when nothing plugged into the input.
Audio Samples:




Here's a tune I whipped up in 10 mins using sampled sounds from this machine
and drums off a magazine cover CD, on the demo of Ableton Live


This is not a commercial product, it is home-made, so is not in new mint condition,
and bears some signs of home-made -ness.
I stand by my craftsmanship, still if any problems arise with it I am happy to help.
