My Ogiri 2015 entry. Now updated with Abacus program. You can see the difference in size, even though my Abacus program doesn't use graphic. MENU.PRG is the one you want to run.

I did try to type from your OSP screenshots but then I got lazy after a couple. Now I finally have an entire collection of your nifty OSPs! Heh, right now I'm flicking the digital beads with my fingers as I would on a real abacus. Brings back memories

Cool! Of course, in the old days, you have to type from magazines. And if you don't have the tape player to store your programs, then you have to type it in every time. :p Compared to that, stylus pecking isn't bad at all. ;)
