Attached to this post are PDF's of the service manuals for some of the Macintosh Quadra and Centris. Enjoy :)

My 2 cents with a couple of files for Quadra 610

Centris 650/Quadra 650 service manual, which came in handy during my recent Centris 650 restoration project.

Just curious if anyone knows of any potentially useful repair and maintenance guides, especially for Quadra-era Macs besides the service manuals? I've come across Larry Pina's books:

• Macintosh Repair & Upgrade Secrets
• Macintosh II Repair and Upgrade Secrets
• The Dead Mac Scrolls

I've only had a quick chance to flick through the PDFs, but it looks like they pre-date Quadras. Do any books exist that covers Quadras? I feel like I've come across one before that might cover Quadras, but my Google-fu is currently failing me.

Troubleshooting Your Macintosh: The Complete, Hands-on Guide to Upgrading and Maintaining Your Macintosh by Douglass High was what I was looking for. I found a copy here https://vintageapple.org/macbooks/pdf/Troubleshooting_Your_Macintosh_1992.pdf
