Hi Rachel,

congratulations to your MC8 - it definitely is a dinosaur ;-) - as well 
as an challenge :-). I try to give you some answers to your questions.

I fear that you have to build your own one. The connector itself is a 
HIROSE connector (see 
http://www.hirose.co.jp/cataloge_hp/e21600015.pdf). See picture on the 
second page of the PDF. I do not exactly know the type of the connector 
since it is not printed on the connector itself but I will send you off 
list some pictures of the connector. To build the cable, I expect that 
it is a 1 to 1 connection (if you need more information, I can do some 
measurements for you).

See above.

I think e.g. an MSY2 of doepfer (www.doepfer.de) should do it. Or a 2nd 
hand Korg KMS-30 might serve as well. I did not try it.

In my opinion, the parts difficult to find will be CPU, RAM and DAC. 
But maybe there are other components hard to find. I do not know about 
any mods.

Well, just a general comment: Compared with todays sequencers, the MC-8 
is a sequencer very, very hard to program. Any error is a nightmare. I 
never managed to work with it without the manual - which means, I wrote 
down notes as a quick reference. And also the MC-8 lose the memory when 
it is switched off. So it is important to set up a tape connection to 
store your daily work and reload it when continuing next day. This 
means, be prepared for a hard work ;-). This is the main reason why I 
stopped to use the MC-8 for now...
