MT-32 Service Notes 1st/2nd Edition

Postby suntac » 2019-2-05 @ 14:38

I am desperately looking for the first or the second edition of MT-32 Service Notes.
Does anyone have it and is willing to share it? Thanks.

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.

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.
