- Well, I know from personal experience that the old 1541's ran very hot, which
- tended to exacerbate their alignment problems. I once wrote a factor analysis
- program for the 64 (basically finds and rotates the eigenvalues and eigenvectors
- of a correlation matrix) that made very heavy use of the drive (virtual memory,
- sort of). On a 50x50 corr. matrix, the program could take hours to run, with
- the drive running constantly. It killed one of my '41s before I wised up
- and built a cooling fan. I never had a heat-related failure or alignment
- problem after that.

- Look through some old Compute or Ahoy mags. Many adds for 1541 cooling fans.

- Dust was not a problem with my design as it included a filter.
