Last night I visited my storage unit and dug up one of those old
caddy-loaded external Apple CD-ROM drives, hooked it up to the 1400 and -
sure enough - it was slow but it worked just fine. Meanwhile I left the 3rd
party CD drive at the storage unit (!) so I can't test out your
boot-with-a-CD-in-the-drive approach until I get back there some time this
coming weekend.

First, be sure you have read this about termination power
 and see if your 3rd party
drive is supplying it.  It's important for powerbooks with IDE internal
drives.

That said:

I have several external Apple and 3rd party CD-ROM drives, that work just
fine with my desktops (4400, 6500, 7100) with the termination switch built
into the external case.  Some are older drives, (1400 era), some new.

No matter what, I can't get those drives to work with my 1400 or 5300
unless I have the drive on AND  a CD in the drive as I power up the machine
(warm boot might work too, I forget).  Regardless of how I terminate them.

If there isn't a CD in the drive when the drive first gets polled, those
powerbook models won't later find a volume OR the external drive until I
first put a CD in the drive, then power cycle the laptop.  Yes, SCSI probe
etc. have been tried,  the device isn't even found on the bus by any of
those apps unless a CD is present at powerup of the laptop, even if the
external drive is on but empty.

Every periph. I own is SCSI, I have more little widgets and ways to get
things connected than I can believe, plus some special auto-sensing
terminators, but I exhausted all my resources and now just put the CD in
the drive before I fire up the laptop.  I don't think the powerbooks SCSI
implementation on these models is "quite right". Yes, I know about the
termination power issue with Powerbooks that have IDE internal drives (see
the lowendmac.com entry for any of these powerbook models).  I also know
that all Apple branded CD-COM drives/cases should be supplying SCSI term.
power just fine, so it should not be an issue.   I'd like to try a PCMCIA
SCSI card sometime and see if the problem persists.   I would bet it does
not.

So before you give up, try that out, if you haven't already.  Holler if it
works.

Is it my 1400 or is it OS 8.x?

[Bruce . Hossfield]

Friends:

I recently got a nice 1400/166 which I am really excited about and which
came with a floppy drive cartridge but no CDROM cartridge. It's running OS
8.0 which I'd like to update to 8.1 and install some other software but I
thought, no problem I'll use my regular external CD drive at least for a
while. Picked up a SCSI adapter. Hooked up the external CD drive - nothing.
Well that's not a big surprise because it's a non-Apple drive.  I figured,
no problem I'll just install Apple CD extension 5.3.1 which reads non-Apple
CD drives and that'll take care of it.

Nothing. Double-checked the Powerbook and adapter by hooking up a Zip Drive
to it, and it works just fine.  Double-checked the CD drive by hooking it
up to a Performa 636 running OS 7.6.1 and CD Extension 5.3.1 and that works
just fine too. As a final check, I hooked the CD drive up to my PM 6500
running OS 8.6 and it won't work on that either.

So now I am forced to conclude that my beloved extension 5.3.1 doesn't work
with OS 8.x !  Can someone confirm this, and can someone tell me if there
is some other way to get this non-Apple external CD drive to work on the
1400 ? (I mean, other than going to 7.6.1 ... ). Last week there was a
thread on this list about jumper settings and SCSI termination on a 1400
with an external drive.  Will it do any good to take this non-Apple drive
apart and start fiddling with the jumpers ??

Thanks for any help,

Bruce
