3: .SH NAME
4: cy \- Cipher/tapemaster magtape interface
5: .SH SYNOPSIS
6: tapemaster0 at vba address ff4000
7: .br
8: .SH DESCRIPTION
9: The Cipher F880, M990/Tapemaster combination provides a standard tape drive
10: interface as described in
11: .IR mt (4).
12: The Cipher F880 tape drive operates at 1600 or 3200 bpi - controlled by a switch on the drive. The Cipher M990 operates at 1600,3200 or 6250 bpi - controlled by switches on the front of the drive.
13: .SH "SEE ALSO"
14: mt(1), tar(1), mt(4)
15: .SH DIAGNOSTICS
16: Listed below are all possible error messages and an explanation of what
17: the messages mean. Any comment related to hardware problems is in no way
18: definitive or complete. Every error will produce one or more messages.
19: Some errors, such as tape is write protected, are displayed on the user's terminal. All system errors are also displayed on the system console with the status that caused the drive to fail.

54: Error messages will be displayed with the drive number (# stands for number), the message and its error code.
55: .sp 1
56: \fBcy#: Drive timed out during transfer\fP.
57: .br
58: Time out errors during transfer; this may be due to trying to read a blank tape or the controller failing to interrupt or the drive dropping off-line ... (Error:01-05)\fR
59: .sp1
60: \fBcy#: Tape is write protected\fP.
61: .br
62: An attempt was made to write on the tape drive when no write ring was present; this message is written only on the terminal of the user who tried to access the tape. (Error:11)\fR
63: .sp1
64: \fBcy#: Drive is not on-line\fP.
65: .br
66: An attempt was made to access the tape while it was offline; this message is written only on the terminal of the user who tried to access the tape. (Error:10)\fR
67: .sp1
68: \fB cy#: Controller referenced non-existent system memory\fP.
69: A memory time-out occurred during a system memory reference. (Error:06)\fR.

74: .sp1
75: \fB cy#: Unsatisfactory media found\fP.
76: .br
77: A tape time-out occured, because the tape drive did not supply an expected read or write strobe. This normally occurs when attempting to read a larger record than was written. It may also occur during a write due to a damaged tape. This message is written on the terminal of the user who tried to access the tape. (Error:0F)\fR
78: .sp1
79: \fBcy#: Checksum error in controller proms\fP.
80: .br
81: An error was detected while calculating a checksum on the PROM. (Error:0E)\fR
