[Coco] floppy disk controller question for those that still use them

[Bob Devries]

Hi, Gene,

don't shoot me for saying this, but.....

I'd assume that you are using the stock rb1773 driver on that disk, and not 
the no-halt one?

Have you noticed any problems reading disks in Disk BASIC (yeah, yeah, I 
know.... I should wash my mouth).

Regards, Bob Devries
