No, you get two replacement ROM's, one for the kernel ROM and the 1571 DCR ROM.
But why buy this stuff? Ask some guy in the forum who could burn these ROMs, that's much cheaper. This $%§/&?!! guy Maurice Randall shouldn't earn money with CMD stuff. A friend here in Germany bought JiffyDOS for several computers, a SuperMMU 128 and some other stuff and got it defective. He sended it back - and never heard anything from him. No response for mails. After a longer time he tried it again using another mail address and like being a new customer, he got a reply. As he told him who he was, the line was dead again. Getting money, yes, but support, no. This is Maurice Randall.
I got my Eproms burned from a friend, as I didn't have an Eprom programmer, and I got them always with a kernel switch Commodore/JiffyDOS. That's probably the switch you see on the photo.
