Service manual for Express?

Is there a service manual for the ETC Express? 

Recently bought a 48/96 from NYC for cheap, looking to fix it up, test it out and donate it to a local high school in need.  I have the chops for this (EE/FW architect at a large tech company) but I'd like to save myself the time of having to reverse engineer everything when I crack it open.  If it works out, I could see doing this semi-regularly.

Occasionally folks post here about specific issues, and ETC comes on with part numbers for stuff that's not on the website.  Such a BOM would be very handy.  Schematics would be too much to ask for ;)

Seriously, maybe it's time to share servicing of these 20 year old boards with the competent DIY/enthusiast crowd, most folks who still have them probably still have them because upgrading is out of budget, and servicing them might be as well.-
