КР1818ВГ93 используется также и в КНГМД Э-85.
Возможно, что исходник драйвера DZ окажется неплохой отправной точкой.
Код:.MCALL .MODULE .MODULE DZ,VERSION=20,COMMENT=<RX50 Mini-Floppy Disk Handler>,AUDIT=YES .SBTTL General Comments ;+ ; This handler serves as the standard RT-PC RX50 device handler. It ; is both the system and non-system handler. It also provides two ; special function capabilities to support physical I/O on the floppy ; as a foreign volume. The special functions are: ; ; Code Action ; ; 377 Absolute sector read. ; WCNT=TRACK, BLK=SECTOR, BUFFER=256 word buffer ; 376 Absolute sector write. Arguments same as code 377. ; ; In standard RT-PC mode, a 2:1 interleave is used on a single track and ; a 2 sector skew is used across tracks. ;- .SBTTL DEFINITIONS .MCALL .DRDEF, .ASSUME, .BR, .ADDR .DRDEF DZ,52,FILST$!SPFUN$,800.,0,0 .DRPTR FETCH=DZLOAD,LOAD=DZLOAD .DREST CLASS=DVC.DK .DRSPF <377> ; Read Absolute .DRSPF <376> ; Write Absolute .SBTTL Constants and defaults .IIF NDF DZ.CMA, DZ.CMA = 173206 ;Interrupt A command register .IIF NDF DZ.CMB, DZ.CMB = 173212 ;Interrupt B command register .IIF NDF DZ.IEN, DZ.IEN = 1 ;Bit number of interrupt enable bit DZ$CS0 = 4 ;Offset from RX5ID to RX5CS0 SPFUNC = 100000 ;Special functions flag in command word SYSPTR = 54 ;Pointer to base of RMON P1EXT = 432 ;Offset from $RMON to external routine GETVEC = 436 ;Offset from $RMON to $GTVEC routine ; RX50 Controller defaults PC$CSR = 174000 ;Base device address of PC option modules PC$VEC = 300 ;Base interrupt vector address for PC options PC$IC1 = 173206 ;PC interrupt controller 1 CSR address PC$IC2 = 173212 ;PC interrupt controller 2 CSR address MMUSR0 = 177572 ;Memory management unit SR0 MMUSR3 = 172516 ;Memory management unit SR3 .IRPC X <01234567> KISAR'X = 172340+<2*X> ;Kernel Instruction PAR'X KISDR'X = 172300+<2*X> ;Kernel Instruction PDR'X .ENDR AP$ACF= 077406 ;4KW page with no trap/abort PROCFG = 37776 ;PAR1 biased address of start of PRO3xx CONFIG table CTI = -10. ;Offset to number of option slots SLOT0 = -14. ;Option slot 0 ID DZ$ID = 2004 ;Hardware device id # for RX50 controller ; Control and status register bit definitions DZ.ID = -4 ;Offset to RX5ID from RX5CS0 ;+ ;Offset and command mode bit definitions of RX5CS0. ;- DZ.CS0 = 0 ;RX5CS0 C0.DSK = 002 ;Disk select C0.DRV = 004 ;Drive select C0.MTO = 010 ;Extended motor timeout C0.FN0 = 020 ;Mask bit for FUNTION BIT 0 C0.FN1 = 040 ;Mask bit for FUNTION BIT 1 C0.FN2 = 100 ;Mask bit for FUNTION BIT 2 C0.STA = 000 ;Read status function C0.RSD = 040 ;Restore drive function C0.RSS = 060 ;Restore subsystem function (RX INIT) C0.RED = 100 ;Read sector function C0.RER = 120 ;Read sector with retries function (EXTENDED) C0.RAD = 140 ;Read address function C0.WRT = 160 ;Write sector C0.DON = 10 ;Done bit ;+ ;These offsets are relative to the RX5CS0 register (X04). ;- DZ.CS1 = 2 ;Offset to RX5CS1 from RX5CS0 DZ.CS2 = 4 ;Offset to RX5CS2 from RX5CS0 DZ.CS3 = 6 ;Offset to RXCS3 from RXCS0 DZ.DB = 14 ;Offset to RX5DB from RX5CS0 DZ.CA = 16 ;Offset to RXCA from RXCS0 DZ.GO = 20 ;Offset to RX5GO from RX5CS0 DZMTRK = 79. ;Highest track ; Error and status register bit definitions RETRY = 8. ;Max number of retries (write function only) DZNREG = 7. ;Number of registers for error log ; Miscellaneous hardware definitions KISAR1 = 172342 ;KT-11 PAR for mapping user buffer
