I've got plenty of floppies, but I've been looking for an 80 column card for my Apple II+. And when are they going to get the Visicalc upgrade released? Seems like years since the last one....
I've still got a few hundred cards, but I didn't realize an II+ would swallow them!
Ahh... Visicalc --- there's a good program.
You wouldn't believe the data analysis I did with that baby. It probably required about three times as many 'phantom' columns for the intermediate calculations as today's spreadsheets would require, but I did some good work on that. Really, though, most of my work today would be just fine with it. The graphics display would be a bit tough to massage into now, though.

I would suggest getting an Apple //e or an Apple //c if you want 80-column support. Although a number of companies designed 80-column cards for the Apple ][+, there was very little consistency in how they were implemented. The Apple //e includes special circuitry on the mother board for 80-column support. Although it needs a plug-in cards to hold an extra bank of memory (which is interleaved with the display memory on the motherboard), all Apple //e computers with 80-column cards (and all Apple //c computers) support 80-column text the same way; all Apple //e computers with the extended 80-column card (and all Apple //c computers) also support double-hi-res the same way.
Some 80-column cards for the Apple ][+ may be of historical instrest, but software compatibility is apt to be dicey. By comparison, almost any software that supports 80-column text will work with a //e or //c.
