The MultiMode product line has been passed through several companies over the years. It started out at Digital Instruments, which was aquired by Veeco in February 1998 before being passed off to Bruker in August 2010.

I've done a good deal of troubleshooting to keep our ancient MultiMode II stumbling along. If you're in a similar situation, check out my notes on:

• Stepper motor control
• Photo-diode signal access
• MultiMode internals
• Closest thing to a description of the NanoScope-MultiMode connection that I can find online. (see Ch. 10)
• A MultiMode manual
