OK, for the archives: I got an answer from Dave Baum (author of nxtcom). He says that error #89 indicates memory fragmentation -- even though my NXT had plenty of free RAM in total, there was no single contiguous block big enough to hold the new (...)

To follow up my own post: I've since verified that I have 45K free on the NXT, and the file I'm installing is under 13K. I've also restarted both my Mac and my NXT, and still get that mysterious error 89. After more experimentation, it does appear (...) (17 years ago, 5-Mar-08, to lugnet.robotics.nxt)

I've been using the nxtcom utility to download NXC apps from my Mac. It was working fine just a few minutes ago, but all of a sudden (starting about 10 minutes ago) it's giving me a "NXT Error #89". I've searched the web and read the read-me, and (...) (17 years ago, 5-Mar-08, to lugnet.robotics.nxt)

You'll need to either get the RCX 2.0 software or use NQC. As far as I know no one has (yet) managed to use the IrDa port and I believe Vista doesn't support Serial ports... you might try a USB to Serial converter, but that doesn't always work. (...) (17 years ago, 3-Mar-08, to lugnet.robotics)

I'm just getting started with bricxcc (and winxp on my mac), so I'm hoping there's something painfully obvious I'm missing.
