I passed your questions on to our Technical Support Manager, as we have had
the HP Documentation CD on our HP3000 since September. Here is what he
said:
We have been using CD Extensions for MPE/ix for about 8 months. These are
some of the issues that I have encountered:
<start>
1. On our PC clients we use WRQ's RNS stack for Windows. This alone is
incompatible with the CD Extensions for MPE/ix. We had to use portions of
our old WRQ DOS stack to make it work. This negated many of the memory
efficiencies we gained by going to a WRQ Windows product. On top of this,
the CD extensions load up in your config.sys and autoexec.bat files, taking
up more or our precious conventional memory.
2. A job for CD extensions must be running at all times. If you stop the
job for whatever reason or dismount the CD to change to an updated CD, your
users will have to REBOOT their clients in order to have access to the CD
again.
3. The performance is at times terrible. Although it is still better than
doing a text string search by hand. We did not realize how the performance
was, until we migrated the CD over to our Novell server.
In the end we have given up on CD extensions for MPE/ix. We now have the CD
mounted on our Novell server. I am convinced this is the best way to go.
We have gained back the memory on the client side, and the performance is
terrific. <end>
We still have the CD-ROM drive on the HP3000. We will use it to create
upgrade tapes once we go to the 5.0 push release. Just doing that saved
enought money in software support costs from HP to pay back the investment
in seven (7)!!! months. In was our HP SE who suggested this to us.

We have been through this discussion two or three times before.
I was reading the HP Advisor (June '95) and found this topic in
the Q's & Views section.
To paraphrase HP's answer, "With HP CD Extensions for MPE/iX
client/server software, PC users can share the same HP 3000
CD-ROM drive ... The server software is bundled into the MPE/iX
5.0 release ... Users that currently do not receive documentation
on CD-ROM, also should order HP LaserROM/PC retrieval software ..."
Sounds to me like HP is saying that LaserROM/PC, running from a
PC client, can access the CD-ROM drive on the HP 3000. My
memory, which is hardly ever perfect, recalls that we could NOT
do this at the time of the last discussion.
I would like to see this happen, but I'm fearful that my hopes
have been raised prematurely. I have called and asked for the
datasheet -- P/N 5962-0050E if you're interested.
