I have an internal hard disk that I converted to an
external SCSI drive.  The problem is that
it works with Mac SE's and Mac II's but not on Mac Plus's.
On a Mac Plus, no disk image comes out.....as if no drive is connected.
The drive was formatted using a Mac II.

All the cables are fine.  I have a SCSI terminator that works.

Does anyone have a fix for this?

I've received the ff. suggestions:
a) my EPROM's are dumb and I might need an upgrade.
b) Mac Plus'es do not provide internal termination, so I need
   a resistor pack in addition to a SCSI terminator.

My disk is a Seagate, 105MB.
Does anyone have Seagate's phone #?

Thanks,
