I think this was simply a configuration problem, not a version problem.

In teTeX and TeXLive the use of PS fonts is activated by the switch  
dvipsPreferOutline when running updmap; this selects the appropriate  
set of map files, referring either to PK fonts or to PS fonts. From / 
usr/local/TeXLive/texmf.local/web2c/updmap.cfg:

> # Should dvips (by default) prefer bitmap fonts or outline fonts
> # if both are available? Independent of this setting, outlines

> # We provide such config files which can be enabled via
> # dvips -Poutline ... resp. dvips -Ppk ...
> #
> # Valid settings for dvipsPreferOutline are true / false:
> dvipsPreferOutline true

and then from /usr/local/TeXLive/bin/powerpc-apple-darwin-current/ 
updmap:

In 1998 there was maybe no teTeX yet (I don't know), but the computer  
with this 1998 dvips may simply have been configured to prefer PK  
fonts, or did not have the PS fonts installed. I'm not even sure the  
CM/PS fonts had been made public domain yet; I think that was around  
1997, but I'm m not sure.
