Hi everyone,
I've orginally posted this in IBM ROM Basic - option ROM for PC clones , but felt it was a bit too off-topic.
So it's here instead. It's a set of files that belonged to a shareware disk from 1987.
Hope that's okay. I didn't mean to bloat the other thread.
When I was little, this was among of my most favorite GW-BASIC programs, especially JET.BAS. ^^

Have fun. ^^

PS: The animated Origami tutorial must be run from A:\ or the source code must be altered (or try to use ASSIGN).
A text editor can automatically do that, if the basic files are in ASCII format. Use SAVE command with ,A to do that.
