There is only one version of the ROM for the 28S (the 2BB).  I know of no
known bugs.  There were two versions of the ROMs for the 28C: 1BB and 1CC.
You see, the third version was major enough to designate it a new calculator.
The 2BB ROMs are very stable.

There does seem to be a lack of a media blitz by HP.  When the 28C came
out, there was a two-page advertisement in IEEE Spectrum.  I haven't seen
anything like that and I feel a little queezy: are *we* the beta-testers
for this machine?

[ Gag, I really hope the rumors of a bug in the Kermit implementation turn
  out to be false! ]
