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.
Any pointers are appreciated!
