MaxTrac Detailed Service Manual 6880102W84, was about $30 but is no longer available (NLA).
This is the low band, high band, UHF, and 800 MHz MaxTrac service manual that covers the MGA, MJA, MQA, MWA and AHA models. If you ever pop a cover on any of those models then you want this book on your shelf... it's chock full of good stuff. You occasionally see these books on eBay and the other auction sites. Until then...

Originally this book arrived as a shrink-wrapped pile of 3-hole punched pages - you had to provide your own thick 3-ring binder. The shrink-wrapped stack was slightly over 2 inches tall. Personally, I used a 3.5" (ring diameter) binder to hold this W84 manual, a 900 MHz Trunked manual (complete with the 30 watt Power Amplifier Supplement), a DeskTrac manual, an RSS manual, some web page printouts, and a dozen sheets of 3-hole punched paper with some modification and programming notes.

I could sure use one. And there do not seem to be any on Ebay.
