It is "LPA Prolog Professional".
The company is

	Logic Programming Associates Ltd,
	  Studio 4,
	    The Royal Victoria Patriotic Building,
	      Trinity Road,
	        London SW18 3SX,
	          England.

Telephone number + 44 (1) 871 2016

The hardware requirements are (quoting the manual):
	An IBM PC, XT, AT, or 100% compatible machine
	At least 512 KB of RAM - 640 KB is preferable
	2 Disc drives, preferably on a hard disc
	...
	You really need about 384 KB of *free* memory to
	adequately run [LPA Prolog Professional].

It supports EMS if you have it, and various mice and such.
Beware:  this is basically an extended micro-PROLOG which has been
hammered on to make it look like an Edinburgh Prolog system and
the differences _do_ show through in places.  You want to read
"Appendix G: Pragmatic Considerations for Programmers" carefully.
