   I currently have Macintosh Allegro Common Lisp.  I would like to use 
   pseudoscheme to program in Scheme under the excellent MACL environment.
   Can anyone point me in the right direction on how to do this??

From altdorf.ai.mit.edu: pub/archive/scheme/scheme-impls.txt:

Implementation:   Pseudoscheme (Scheme embedded in Common Lisp)
Implemented by:	  Jonathan Rees
Support:	  Unsupported, although I'll probably continue to improve it.
Hardware, etc.:	  Will run in any implementation of Common Lisp.
Availability:	  Free.  Distributed as source via anonymous FTP from
		  altdorf.ai.mit.edu: archive/pseudo/pseudo-2-7.tar.Z.
Dialect:	  Subset.  Tail-recursion is not supported except in the
		  special case that a loop is found statically, which is
		  when the loop is written explicitly using LETREC or
		  something that expands into LETREC (DO, named LET,
		  internal DEFINE).  Tail-recursion will of course be
		  inherited from the host Common Lisp if it has it.
		  All of the essential features of R^3 Scheme exist,
		  except for a correct CALL-WITH-CURRENT-CONTINUATION (some
		  of you will say that it's not Scheme at all, and I don't
		  disagree) and number exactness; most of the non-essential
		  features are there too.
Intended use:     Running most Scheme programs using any Common Lisp.
Implementation:   A preprocessor translates Scheme code into Common Lisp
		  code, which is then interpreted or compiled by the host
		  Common Lisp system.
Remarks:	  I did this mostly for my own personal use.  Maybe other
		  people will find it useful too.
