I am relieved to see that > there were no changes to the part between DOS 2.0 and 2.1; All DOS 2 versions use the 901466-04 6530-034. All DOS 1 versions use the 901466-01 or 901466-02 6530-028. The 901466-01 and the 901466-02 have the same rom content. The difference is at this time unknown! But all DC-RRIOTS (6530-028, 6530-034, 6530-036, 6530-038, 6530-039, 6530-040, 6530-044, 6530-047 and 6530-048) use the same address programmable logic. So only the rom content is changed. Look at the 8250LP or the SFD1001, there don't exists a new RRIOT. They used an old RRIOT on an adapter board and put the rom content in an additional eprom. On the same way, you can use any RRIOT above to repair any commodore floppy disc drive. Martin Message was sent through the cbm-hackers mailing listReceived on 2012-06-22 12:00:35
