Smalltalk 80 VM

Dan Banay released (on the day of the 80th anniversary of Alan Kay) a fully functional Smalltalk-80 VM capable of running the original ST-80 images as distributed by Xerox Parc in 1979 and 1980. Really nice, especially when you check the code which is available on

Compendium for Pharo

Compendium for Pharo is now able to show a list per repository and a list of repos per author for the GitHub projects.

Pandemics were explained and visualized by Alan back in 1998 using Squeak Smalltalk and particle simulation in Morphic in this video:

Pharo and Repl.it

I tried repl.it  with a simple script to download and run Pharo headless and also Pharo UI Works nicely - within the top right part of the browser window one can even see and use the Pharo window.

Clickable but X-Windows emulation does not seem to show the full window (try clicking on "full screen mode" in the welcome window to adjust this).

Try this https://repl.it/@astares/Run-Pharo-9#main.sh

Just consider to create an own account on repl.it and use the following code in a main.sh:


echo *********************************************
echo * Download and run Pharo
echo *********************************************

# prepare
if [ -d build ]; then rm -Rf build; fi
mkdir build
cd build

# download 
wget -O- https://get.pharo.org/64/90+vm | bash

# run
./pharo-ui ./Pharo.image
