I saw Zane's post, and sadly, am not close enough to go pick up
his Integral and give him some cash... but I *am* looking for one,
if anybody has one that they'll part with ( and I WILL pay a reasonable
price). I've wanted one ever since I read the review in PC Magazine so
long ago...
Thanks.

Bill,
I have one that I can part with. The floppy drive is bad though, so I
have been meaning to replace it. Also, it could do with more memory (if
anyone has extra, please let me know). Does anyone know of a source for
replacement drives? The original ones seem really fragile as almost all
that I see have broken heads.
Also, check out my Integral site
(http://www.coho.org/~pete/IPC/integral.html). It has information about
the Integral and software to download.

This has been discussed here several times before. The HP double sided
floppy drives are notorious for this. The grease on the mechanism gets
stiff and the drive doesn't open all the way. That causes the top head to
catch on the floppy disks. If you insert a disk with the drive like that, I
can just about guarantee that you'll catch the top head and tear it loose.
If you then try to use a disk in that drive, you'll damage the media on it.
ANYTIME you use a double sided HP floppy drive, you should watch for
problems with it not opening all the way. If you catch the problem in time,
you can remove the drive and clean off the old grease and regrease the
drive and it will be fine. I use alcohol or spray tuner cleaner or
something like that to clean the old grease off and then apply a good
qualtity gun grease that won't get gummy with age. I haven't tried it yet
but I think you can rob a DS floppy drive out of an external HP disk drive
and use it to replace the one in the IPC. External drives like the HP 9122
or 9123 floppy drives or the HP 7957 or 9153 etc combination hard
drive/floppy drives aren't too hard to find in scrap places.
Also, check out my Integral site
(http://www.coho.org/~pete/IPC/integral.html). It has information about

Nice web page. I've been intending to put one up for the IPC and some
the other HP computers but I haven't had the time. I have 8 IPCs at the
moment, they're one of my favorites.

Tony,
I believe that you are right about the 9154. That brings to mind another
question about that drive. My 9154 has a half height 3.5" Sony drive
with the 34 pin connector. However, there is no power connector for the
floppy. Other Sony floppies that I have seen have the 34 pin connector
and an extra 4 wire power connector. Can I use other floppies on the HP
drive? I tried one last night and the 9154 would not even power on with
a standard Sony floppy (the fan would not even come on).
On a related note, the hard disks in the 9154 are supposed to be 20MB
3.5" SCSI drives, but they use a smaller connector that I am not
familiar with, and again no power connector. Is there some standard for
SCSI that came before the normal SCSI-1 type connector or did HP do some
proprietary type of connector?
Thanks,
-Pete

I thought the 9153 used the
half-height drive with the 34 pin connector.
I've never pulled one apart, but I have the 9154 (same unit _without the
floppy drive_) on my HP150-II and it certainly appears that such a drive
would drop in.
A 9133 uses the full-height drive that we've been discussing, though. As
does the 9114A HPIL drive.

Of course, they could all be getting their information from the same
incorrect source. In a way though, SCSI does make sense since the drives
do have integrated drive electronics. From the period, the only drives
that I know of with integrated controllers were either SCSI or SASI. I
thought that SASI was only used by Shuggart. The PC versions did not
appear until about 1988 (later than the 9153/9154), and I doubt that HP
(at that time) would have use the PC types anyway.
At some point, I will pull the integrated controller board off the disk
and look to see if any standard parts were used. Also, the chips that I
can see on the main board in the drive seem to use HP ASICs (an 84 and a
68 pin CQFP).

Are you sure it's SCSI? I thought it was some custom interface. It
certainly didn't look like SCSI to me...

Back in the mid-80's I had a Quantum Q2020 16mb 8" hard drive with a
bolt-on SASI controller. It gave this behomoth a 50-pin sasi jack to
which I connected my Atari's BlackBox host adapter. I don't remember who
made the controller board.
It had a huge power supply hanging off it's side, and a 'smoked' plastic
bubble covering the platters. You could see the mech working if you shone
a light through the plastic. Despite the !ouch! mechanical warning
stickers all over it, it ran very quitely.
I just loved that drive. :-)
Unlike the scsi drives which I also ran on my Black Box and/or MIO scsi
host adapters, this Sasi drive did not map-out it's own bad sectors.
After formatting (special program), you would run a high-level scan of the
drive's surface. The program put a special file in the root of the drive
which 'occupied' all of the bad sectors on the drive.
Also, the Konan DJ-210, WD1002SHD, and both Xebec S1410 controllers were
Bridge adapters from ST506/412 to SASI. You used LUNs to run more than one
mech on the bridge (except WD1002 only 1 drive) just like a SCSI bridge.
I know the BB and MIO interfaces for the atari ran both, but I'm wondering
if today's PC host adapters will run really old devices like those old
bridge controllers?
Rambling.....
