- I tried an Exabyte-8200 out on my 1000 with a Supra SCSI controller
- using BTN-Tape handler. I did not do extensive testing (it was a
- loaner) but I 'tar'ed my 64 meg hardrive, read a file or two back to
- the disk and did a table of contents listing, all with no problems.

- Exabyte drives need to be internally terminated since there is no way
- to supply the +5 volts needed for external terminators. This means they
- are either pass through (no internal terms) or end the SCSI bus (with
- terms). The newer exabytes use SIP resistor packages (220/330 ohms I
- think), the same as the terminators used in most SCSI drives,
- older Exabytes use a DIP package, a little more difficult to find. A
- word of warning, make sure you follow the little *dot* that indicates
- pin #1 on the SIP and match it with a pin #1 indicator on the PCB
- (either a square pad or a silk-scrren number 1). The SCSI ID is set
- with little jumpers, look for a set of 6 L-shaped connector pins close
- to the (left ?) edge of the PC Board with the SCSI ribbon cable
- connector on it. From left to right is bit 1,2 and 4. Adding a jumper
- block, connecting the upper and lower pins, turns that bit on. You
- would *probably* want one jumper in bit position 4: that is SCSI ID #4,
- the default location for AmigaDOS 2.04's magtape command.
