This is beginning to make some sort of sense.

I've got an 8r.mtx file with my fontinst installation.  There's one in
finst's CTAN directory too:

9707     37 fonts/psfonts/tools/finst/8r.mtx

One question: this command \raw_encoding.  It appears to be set to 8r, but
the raw encoding of the average `foreign' fount you install for use with
(La)TeX is 8a.  8r is called the TeXBase1 encoding.  Can anyone explain the
discrepancy?
