[comp.sys.mac.hardware] Dataframe XP60 question

jacobson@ux1.cso.uiuc.edu (R J Jacobson) (11/09/90)

About 1 year ago our user group bought a used Dataframe XP60 HD (Supermac)
It is working fine, but we did not get any documentation with it. One of
these days I have plans to add a CD-ROM drive to the pass through. WE
are running the Dataframe on our BBS. I am not real familiar with
external termination and such but I keep seeing posts about it and
am wondering what kind of termination the Dataframe has. Will I be able
to add the CD ROM as the second in the chain from the Dataframe using the
SCSI pass through?  It is running off a Mac Plus at this time. The Mac
Plus is being repaired or will (power supply went) as did the floppy
drive. I saw the note about the problems with internal termination
on a Hard Drive and the way the Mac Plus SCSI is implemented. So I am
also wondering if what I want to do will even be feasable with the
Dataframe and Mac Plus. Before I get a CD ROM I would like to know
what problems if any I should expect. And if I need to purchase a
particular brand that would work fine with the setup we have. It is
possible that we will simply replace the Plus with a new Classic if our
group can find the means to do it. So that is another factor in the
equation.
 
Anyway if any of the readers of this newsgroup are familiar with the
Dataframe line from Supermac, and in particular the 60 Meger I am talking
about I would like to hear from you via email. What problems have you had
if any, with adding other SCSI devices to the SCSI port of the Dataframe?
Can I expect to be able to add a CD ROM drive to this setup or will the
Dataframe have the wrong kind of termination to allow me to do this.
Everything is internal on the drive, so I assume it has internal termination.
If this is so will it cause me trouble. The various notes I have seen about
all this made me want to find out what I am in for before I go any further
in the direction of getting a CD-ROM drive to add to the setup. Thanks in
in advance for any input you can give me on this!!
