Thanks to Wouter Scholten for these images of an Acorn Atom. Thanks also for the info with the pictures


Click on the images for bigger ones.

Hardware:


 

BBC and Atom modes:

Somewhat crappy images due to my camera which doesn't work well photographing computer screens (no-flash mode)


Note that in Atom mode, one needs to use FPRINT to print floating point numbers, and that REPORT only works for the BBC mode (The standard Atom doesn't have REPORT)..
