i would really appreciate it if anyone on this list can respond
to my question. i have just shot two cartridges of Tri x super 8 film, one is
7266 and the other is 7278. is the handprocessing the same for both?

From George Selinsky's great page:

  IMPORTANT NOTICE for those developing KODAK BLACK
  As of October 1st, 2003 Eastman Kodak has introduced two new
  black and white reversal films that are to replace the older Plus-X 7276 and
  Tri-X 7278 films. They are to be called Plus-X 7265 and Tri-X 7266. Kodak
  reformulated these films to accomodate a new black and white reversal process
  that uses a new environmentally safe bleach and a higher energy developer. The
  new R-10 bleach does not use the metallic compounds that the older R-9 used,
  therefore making it more environmentally friendly and less costly to dispose
  of. The new developer/bleach combination allows Plus-X film to be exposed at
  100 ASA.
  In addition, the new Plus-X features increased sensitivity
  (100 ASA in daylight) at what Kodak terms a slight grain
  penalty, while the new Tri-X features finer grain for its 200 ASA
  (daylight) speed and lower contrast than its older brother, 7278.
  Kodak claims full cross compatibility - the older films can be
  developed using the new chemical formulas, and the new films can be developed
  using the old classic formulas. However, it is important to note that
  both the new and old Plus-X films are to be
  exposed at 50 ASA (daylight) when being developed in the old
  chemistry, and 100 ASA when developed in the new chemistry.
  There is no change with the Tri-X films, as far as I am aware from Kodak's
  Most laboratories intend to switch to the new process on
  October 1st, 2003. If you have Plus-X film that has been exposed at 50
  ASA, and have not processed it yet - either get it to a lab that still uses
  the old process, or develop it yourself using the Kodak specifications below
  or any of the other classic formulae on the net.
  I have not tested these new films or process combinations, nor
  do I currently have the new formulae (the Kodak D-94a developer and the R-10
  bleach) - but Kodak said that it would be releasing the formulas around
  December of 2003 on their webpage. The processing information I have on this
  webpage does not yet reflect the new process. Check the Kodak webpage (cinematography section) and
  the Kodak
  FAQ on these two new films for more detailed information.
