I also have a colour one which induces far more nostalgia, alas, it's 200 chars.

I think we have enough to write a full emulator now.

:D I wish we could amalgamate dweets into a super dweet! We could build the GEM desktop 140 chars at a time.

Oh the nostalgia! #basic #prompt
u/magna

I've realized I could have encoded the bitmap data a lot more efficiently. Will try to shave some chars to add translucency to the font and add a blinking cursor.

thank you for cleaning up my idea ;) your solution is very neat
u/iverjo

Thanks :) It lacks the yellow color, though. I'm not sure I could hack that in without removing the rectangles
