 Andy Holder referenced a thesis by James Ruiz U. of Austin, 1990.
 Dissertation Abstracts Int. Vol 50 p4019B (1990) gives an abstract
 of the thesis dated 1989. This thesis abstract does not specifically
 mention "SAM1", it does cite AM1 and alludes to a new method as
 applied to hydrocarbons. This thesis is available under order number
 DA9005659 from the service (usually a microprinted edition) phone in
 orders through 800-343-5299, ext 781 (Canada); 800-521-3042 (USA). One
 convenience DA Service takes credit cards, which avoids having to pay
 outrageous bank charges to secure checks payable in $ outside the USA.
 In my priprint copy of the paper by Dewar, Jie, and Yu (kindly sent to
 me by Andy Holder, the published Tetrahedron article has not yet arrived
 in Paris) there are no tables of SAM1 parameters for the C,H,N,O atoms.
 one suspects that these two above literature sources are insufficient to
 permit the independent investigator to reproduce SAM1 calculations.
 Personally, we run AMPAC 4.5 so my ox is not gored. It is a good
 program and worth the money.  Many who do semiempirical calculations
 accept they are voo-doo quantum mechanics and one has to go to the right
 witchdoctor. I still cry a little for my 3rd world colleagues in not
 being able to join the club.
