I have finally made a near 100% clone of the MC16. The card was used in the early version of the Alpha Syntauri before switching to the Mountain Computer Music System. 5 Cards can be used with the Alpha Syntauri software and 3 cards with the ALF software.
The card has some differences to the original but it has the same components and the same Layout.
Bugs in the current Layout:
- One connection from DAC3 to the opamp is missing, resulting in a missing voice. Solution: solder an airwire.
- The holes for the 3-pin connectors are too small. Solution: drill them wider.
These bugs will be corrected when i make the layout puplic. Since it is rather hard to get the components, the usability for the community is limited.
I may do a small run of 20 cards. The price would propably be between $60-$90 per card.
I have difficulties to source the 1782Khz Quarz. I have some CSA1.782M resonators but they are not precise enough.
