Apple II

I own an Apple II Europlus, but currently live in north america. I've been considering swapping the crystal and converting the machine to NTSC colour, and I just ordered the parts to do so. As the parts were being shipped, I finally got around to setting up an ADTPro disk (I've just used this machine for writing BASIC programs occasionally up until this point), and I used it to re-burn my diskette of oregon trail that was corrupted. In this process I noticed that I appear to be getting colour out of the machine already (inside the game).

After a 40 year hiatus, I'm having fun reintroducing myself to the Apple II. I've picked up two IIe systems from local sellers, leaving me with an array of cards: SSC2, LIRON, Buffered Grappler+, a few different disk controllers. I've downloaded and used Card Cat 1.6 to confirm that the cards are identified correctly, but is there any software out there that can run diagnostics to see if these old cards are still working properly? I can probably test the SSC2 with ADTPro and the LIRON with the Floppy Emu I picked up, but I have no real way of knowing if the Grappler is working.

I have a copy of Wizardry both in 5.25" floppy form as well as a CFFA disk image. While I can run the game fine from the 5.25" drive, I can't get the images to run after the logo screen from the CFFA, or write one to 3.5" disk and run it using that drive. Does anybody have advice?
