[Cuis-dev] [offtopic] Bare metal Smalltalk-80 port to the Raspberry Pi

[ken.dickey at whidbey.com]

Greetings,

I made an SD card and the system came up on a RasPi 3 but NOT a RasPi 4.

I did have to make adjustments to config.txt for my HDMI display 
(attached).

The Circle bare metal code is quite brittle/fragile.  E.g. 
missed/duplicate keystrokes.

Date dateAndTimeNow --> nil

But I was able to write to and read from a text file in ST-80.  Also, 
able to read file from the SD card.

Cheers,
-KenD
