VIC Disk Details
I own a Commodore VIC-20. I need a disk drive now, but I do not want to get a 1541 because I may upgrade to a PET in the future and do not want to buy a whole new drive. If I use a VIC to IEEE-488 interface to a 2031 drive, will I retain all the standard Commodore disk commands? Will I need DOS for the 2031 or the 1541? Please help.
You will retain all of the standard commands. One of the main reasons for the manufacturing of an IEEE-488 interface is for upgrade adaptations like the one you're contemplating. There are several such interfaces on the market now. DOS is built into both the 2031 and the 1541.
