Hi all,
some time ago I have purchased a fully working HP IPC on Ebay. I have replaced the broken floppy with a fully renewed replacement (same type) and meanwhile I got some copies of the floppies. But because I don't have any manual, I have absolutely no idea how to access the programs on the floppies. I don't know a way to use the PAM to start anything usefull.
Is there anyone who can give me a hint?
An additional question. Is there anyone who has a copy of the HP Journal Oct 1985 (can't be found at HP).
Kind regards
Andre

Andre, take a look at http://www.coho.org/~pete/IPC/integral.html as a starting point. In order to use programs on floppy, you'll need to mount the floppy - essentially you'd use the same command to do this as modern UNIXen and Linux. I'm not sure what the mount point would be, though; I only used an Integral briefly when they were first introduced. Best,

Each floppy has a volume label, and the system automatically mounts it in a directory with the same name as the volume label. So if you insert a floppy with a volume label of foo, it will be mounted in /foo **vp ▼

Connect the external HP-IB hard drive and look in /dev to see the name(s) assigned to the hard drive. Then use the format_disc utility (int he Utilities diskette) to format it. I hope this is correct because its been ages since I formatted my hard disk. **vp ▼

There are many different models in the 9133 family and I have a 9133H connected to my IPC. I have the manual for this drive but it is written by brain dead people (whenever a manual starts with "Don't let the terminology scare you", you know that the manual is not worth the paper its printed on). Anyway it says zip about the configuration switch other than "it changes disc formatting". Thanks! Anyway the setting that works for me is Configuration switch in position 1, address in position 0. With these settings, I get:

I use an original double sided double density PC disk drive connected to a Unix system (OpenBSD). I then use the Unix utility dd to copy the image to the drive.
You may be able to use Tony Duell's LIFDUMP utility instead **vp

If you have an HP device that used the original full-height Sony drives (HP9122, HP9123, HP9133, HP9114A, Integral, etc), then you MUST strip down the eject mechanism and regrease it. If you don't there's a very real risk that it won't latch up properly and when you try to eject a disk, the upper head will catch in the disk and be ripped off its mounting. The only cure for that is to replace the head carriage assembly and do a full alignment. Needless to say this is a lot more work... Basically, you take the drive out of the machine and remove the mounting brackets. Take off the top cover (1 screw), the logic board (3 screws and connectors), the front panel if fitted (it isn't in the Integral), then the eject damper (1 screw, rear left of the drive), the head load solenoid/bracket (2 screws) and finally the disk holder itself (4 screws). That then comes apart by removing 1 more screw and slipping off the E-circlips. Clean off all the old grease using a suitable solvent and apply a _trace_ of new grease. Put it all back together. One other point: High density disks do not work in these drives. Not only is the coercivity wrong, but the disk-inserted sensor lines up with the HD-detect hole, so it's not operated. The result is that the drive thinks it doesn't have a disk installed. ▼

You are right, ▼

a) you did not mention which TYPE of 9133 you have. The front label will prob. just say 9133, but the back label should include the letter designation. I assume you have the 9133H but I am only guessing. b) When you power up the 9133 what is the behaviour of the two LEDs in the front of the drive? **vp ▼

There are two LEDs the RED (fault) and the YELLOW (access). For normal operation, both LEDs should be off with the YELLOW one coming on when there are accesses to the disc. **vp ▼

The floppy drive of one 9133 now works as replacement drive within another 9133 and the other floppy drive of a 9133 works as a replacement drive within an integral pc. The replacement drives are running quite well, but I have simply not put the broken drives into the 9133. ▼

Andre Koppel wrote: I went and removed the floppy drive from my 9133H. The yellow LED indeed stays always on. Despite this, the IPC recognises the drive and mounts the partition. I assume that you have tried the 9133H with another computer and it works OK. I am completely perplexed. **vp

Good call, Vassilis. HP lent me an Integral for review when it was first released, around 20 years ago. Sure wish I had one now. . . . Best,

Actually, Les and Vassilis are both correct. The first release of the IPC was a mix resembling UNIX System 3. That required the mount disc to run. An upgrade, System V made the mount disc automatic. I wound up with both versions after I returned the computer for repair and HP gave me a System V module. I always ran V. Joe
