CM-500/300 Service Notes

[reines]

Hi,

Did the CM-500 have a second/third edition of the "service notes" manual? I wonder, as the photo in the First Edition CM-500/300 service notes shows only the GS logo. Or the hardware changes did not justify a new edition?

If it had, any idea where it can be found/bought?

Thanks,
Reines

Only First Edition service notes exist for the CM-300/500. Subsequent editions were only produced following major hardware changes (hence the three editions for the MT-32). The differences between CM-500 models are software-based, and were likely covered by a service bulletin.
