 I am interested in controling an input/output card via Logo on an IBM clone.
Years ago I was able to control a small "turtle" like "robot" using an Apple
2e computer, and Apple Logo via that machines "games" port. From memory it 
was as simple as using ".examine" and ".deposit" to read and set bytes in the Apples 64K memory
map corresponding to the games port addresses. I have long since lost the 
details. My input/ output cd uses Intel 8255's at hex 1b0-1b3 and 1b4-1b7.
If I could read and write to port addresses I could use the card.
Can this be done using "doslogo" ?

I have downloaded a copy of ftlogo from a ftp site. It seems to work with on

Berkeley Logo doesn't have .examine or .deposit, but it shouldn't be
hard to add.  I'll put that on the list for the next version.
