The Commodore D9060 and D9090 can use the same firmware. The difference between these units is that the jumper J14 on the DOS board is open in the D9060, and closed in the D9090 to select a 4-head vs. 6-head drive. The jumper J13 seems to be unused.
According to Wolfgang Günther, the EPROM type may be 2564 or 2764, depending on the board version ("Assy No. 300012-001, Rev.B" or "Assy No. 300012-002, Rev.A"). This is the case of 300516/300517 rev.C.
