The catalog command gives me an I/O error when I use "CATALOG D2" or "CATALOG D1" or "CATALOG"
I have 2 disk drives, one of which is "brand new" and has been tested by an expert on another system.
The other disk drive is also functional but has not been tested by an expert, it only boot up disks fine (most of the time)
The disk ][ controller is old but seems to work fine when used with a single disk. I have only recently used it with two disks
My system is unable to CATALOG even fully functional disks which boot up and run fine (like Ms Pacman, Choplifter)
The same system can CATALOG other disks (like DOS 3.3, Graphics Magician)
The problem occurs whether I CATALOG from the new D1 or the old D2
I have a 48K+16K language card Apple II non-plus.
What am I doing wrong?
