        Once again T is Touted as "... the most efficient and portable
Lisp to appear on the market." As one of the people associated with
the development of PSL (Portable Standard LISP) at the University of
Utah, I feel that I must point out that PSL has been ported to the
Apollo, VAX/UNIX, DECSystem-20/TOPS-20, HP9836/???, Wicat/!?!?!?, and
versions are currently being implemented for the CRAY and 370
families.

The predecessor system "Standard LISP" along with the REDUCE symbolic 
algebra system ran on the following machines (as October 1979):  
Amdahl: 470V/6; CDC: 640, 6600, 7600, Cyber 76; Burroughs: B6700,
B7700; DEC: PDP-10, DECsystem-10, DECsystem-20; CEMA: ES 1040;
Fujitsu: FACOM M-190; Hitachi: MITAC M-160, M-180; Honneywell: 66/60;
Honeywell-Bull:  1642; IBM: 360/44, 360/67, 360/75, 360/91, 370/155,
370/158, 370/165, 370/168, 3033, 370/195; ITEL: AS-6; Siemens: 4004;
Telefunken: TR 440; and UNIVAC: 1108, 1110.

  Then experiments began to port the system without having to deal
with a hand-coded LISP system which was slightly or grossly different
for each machine. This lead to a series of P-coded implementations
(for the 20, PDP-11, Z80, and Cray). This then lead via the Portable
LISP Compiler (Hearn and Griss) to the current compiler-based PSL
system.

So lets hear more about the good ideas in T and fewer nebulous 
comments like: "more efficient and portable".
