Apple II

I bought some 5.25 disks on eBay. They are MD2-HD (1.2MB MSDOS format) high density disks. But when I put them in the Apple IIc and to INIT HELLO, it does not format the disk. Instead I get a I/O Error.

What is going on? I thought you could format HD disks as SD... ? Can someone tell me how to fix this, thanks. Or where to get SD disks.

Hi!

I have a vintage cassette tape program released by subLOGIC in the late seventies. The label says: SUBLOGIC 6502 / APPLE II 3D GRAPHICS. I would like to boot it up on my Apple II+ computer. Can someone assist me in finding the right memory/exec addresses?
Thanks! Marc
