The day my C1 died was a sad one indeed. Loved the ease of the Voyetra sequencing software, and not having to use an outboard midi patchbay back then was awesome. With 8 outs and 2 ins I easily ran my entire studio, including:

Juno 106
Cheetah MS-6
Cheetah MS800
Oberheim Matrix 6R
Roland D110
Yamaha SPX-900
ART SGX2000
+ a pair of midi-CV boxes to drive older analogs.

Would love to have that rig again...

Kraftwerk''s Electric Cafe was recorded during 83-86 with the Synclavier. Two C1 machines were used on stage in late 90''s only

Does anyone want a Yamaha C1 music computer? It runs, crt display seems a little flaky. It''s been in storage for 20 years.

You have run a sequencer with a 3.5 inch d diskette to run the sequencer program.(Added on August 24 ~ 2017), we copied the diskette capacity over the diskette capacity to the diskette capacity, and then copied it into two chapters.(Hard Installator) has copied the files from the Dosbox program to the hard disk.However, the program was able to copy the program to the second bootable disk, but it was repeated repeatedly and tried to succeed several times before attempting to succeed. Maybe it''s because the floppy disk is all about the same errors, so it might be stale old, and it might have been stale or broken. $$12640$$$12640$
Anyway, I tried to play a song called Minute, but I was only able to install a vapi driver, and it was impossible for me to play the violin. $$12640$$$12640$
However, you could not run the drive.bat file with a diskette error. Maybe it''s a driver setup file ...

I''m trying to repair a C1 that starts up with the external display LED always on. No disk seeking or anything, and the dip switch for display on the back does nothing. The screen does not light up.

I did a dump of the BIOS EPROMs from the machine and it looks like they''re corrupt, a sign of "bitrot." The letter P for Pheonix is corrupted in the dump, and I looked at dumps of another Phoenix BIOS and it looked proper.

I''m looking for someone with a working machine to run a dos utility to dump the BIOS. There is a 3rd EPROM in the machines, not sure what it does $ but the BIOS dump utilities will not be able to dump it. I am going to re-read my EPROMs to make sure it wasn''t a bad read. I''m interested in how other people''s units are failing, and I think it would be a good thing to get the EPROMs from a working unit saved off.

I have a good amount of documentation and original disks, I will put them all online. I''m putting all my notes with regards to repair online as well.

I used to own one of these machines back in 1993. It had a CGA display, but in monochorme blue. It also had a 20mb H.D. and a 740K floppy disk as far as I remember. I mostly used it for learning to type. Eventually selling it to somebody who wanted it for music mixing.
