I have just put a new little subdirectory on the UIUC server.  It should all work with Squeak 2.5 or 2.6 (and myabe older versions too)

	Goodies/Smalltalk-72/
containing...
	Smalltalk-72-di.cs
	ALLDEFS
	ST72Font10.sf2

To quote from the preamble of Smalltalk-72-di.cs...
This file implements Smalltalk-72 within Squeak.  In addition to this file you should have
	ALLDEFS -- the nearly original bootstrap file with updated comments
	ST72Font10.sf2 -- the original ST-72 font, converted from Alto format.

After filing in, execute...

	ST72Context bootFrom: 'ALLDEFS'

This will open a transcript, and read the file of bootstrap definitions.
You should then follow instructions shown in the transcript.

The following things DO WORK at this point...
	The scrolling read-eval-print loop
	The menu-driven code editor
	The pretty printer
	The turtle

The following things do NOT yet work
	The file system
		(this should all be thrown out and replaced by
		a simple set of primitives using the Squeak file system)
	The debugger
		(it was never much, but it would be nice to show
		a walkback and then do an automatic restart)
	The leech class, used by the debugger and classPrinter
		(some of the class table format has changed, and we
		might want to go back to the integer accessor codes)

Some fun things to type in the ST-72 window (followed by cursor-up)...
	3 + 4				The smoke test.
	355.0 / 113			Test floating-point.
	for i _ 1 to 300 do (@ go i turn 89)	Turtle geometry example

Enjoy.
