-
- Did you buy the drive used? Is it configured properly?
-
- Even my office A1000 (w/ Supra 4x4, Quantum HDs, Archive 2150S) keeps the
- tape drive streaming using AmigaTAR and BTNtape (both reads AND writes).
-
- You didn't identify which Amiga and AmigaOS version you're using, nor did you
- identify the SCSI controller.
-
- I have *ALL* my Archive 2150S drives (on Amigas, Suns, SGIs, etc.) configured
- for the factory-default 16K buffer; perhaps that's your problem.
-
- Enclosed are the jumper settings for the 2060S/2150S which I usually post
- to comp.periphs.scsi every month or so.

- Viper 2060S and 2150S hardware setup
-
-
- Hardware setup amongst the 9 sets of jumpers includes:
-
- SCSI ID: 3 sets of jumpers
- Serial: this should NOT be set
- Diagnostic: this should NOT be set
- Parity Enable: setting depends on your interface; either EVERYTHING
- or NOTHING on the bus should be checking parity.
- Buffer Disc: 3 sets of jumpers select 2, 4, 6, 8, 12, 16, 24 and
- 32K buffer sizes. Factory default is 16K. This is
- the number of bytes transferred over the bus in a
- single operation. A mininum of 16K is required for
- the SCSI "COPY" command.
-
-
- Where to find all this at the back of the drive:
-
- [OOOO] TTTTTTTT TTTTTTTT TTTTTTTT
- [JJ] SSSSSSSSSSSSSSSSSSSSSSSSSS
-
- Where: [OOOO] is the power connector
- [JJ] is the jumper block
- TTTTTT are the three 8-pin terminators
- SSSSSS is the 25x2 SCSI connector
-
- The jumper block looks like this (in the orientation as above):
-
- [ SERIAL ] [ CF2 ] [ ID2 ]
- [ DIAG. ] [ CF1 ] [ ID1 ]
- [ PARITY ] [ CF0 ] [ ID0 ]
-
- SERIAL: no jumper
- DIAG: no jumper
- PARITY: jumper to enable
