Best I have currently is the rev3 notes/manual with schematic.

Thanks, but I specifically need the service manual for the old version of MT-32.

dang, I also have the 3rd edition as well...
maybe Solarstorm here can take some photos?
Re: MT32 Old schematic

I have a photocopy of the second edition, meaning the quality is not the greatest. Do you need some specific information, so I would only have to scan one or two pages, or the whole sixteen pages?

Thanks, mate 😀
I'd need just any info regarding the HG61H15B59F gate array, i.e. the pinout, its internal diagram and the part of the schematic which involves the gate array, 8095, and the nearby RAMs and ROMs.
I'd be very glad if you'd scan it for me.

Would it make sense to ask Roland if they still have this on file? Or are they not ... that nice?

Download my scan of the 2nd edition here (11 MiB). I will delete the file in a couple of days, and remove the link, so don't quote the link.

Because I only have a photocopy, the quality is not great, in particular the gray area on page 2, and the schematics are rather hard to read.

Thank you - I owe you one.
The quality is not great, but it is still way better than having to reverse engineer the schematics from scratch.

Took me a while, but here is my scan.

Thank you, Solarstorm. That must have been a lot of work! You are the best.

It wasn't that much work at all, i used a Kyocera TaskAlfa 3500i to scan a complete A3 page direct to USB.
But my stupid brain always forgott to take the service notes to work where that machine is. 😁

As an owner of a first edition MT-32 I thank you very much!

yep thank you as well for scanning this!

Yeah, no problem, get it as long as it's online.
I don't think there will be a DCMA takedown, but you never know.
Grab it while it's hot! 😁

Upload it to the internet archive. They have lots of manuals and historic stuff.

Let's see how that turnes out.

I also sent it to console5 to host it and add it to the new Wiki they are putting together for the MT-32.

Link?

Would someone mind please rehosting the 2nd edition files? I have a NWI modified MT-32 that I am going to try to document the modifications for the community but I would rather not have to figure out the schematics from scratch. TY!
