Subject: Small VME Backplanes?
Does anyone know of a source for inexpesive, small VMEBus backplanes? I'm
looking for something 1, 2, 3 or 4 slots, preferably 6U, so that I can put
VMEBus cards in a case smaller than a 19" rackmount. Cardcage would be
optional.

Assuming that you have verified that the front panel works correctly by
removing the 16FDC (and only the 16FDC), then the first thing that I
would check is to see if the 16FDC is grounding pin 20 (UNPROT)
of the s-100 bus.
If it is, a quick glance at the Imsai panel schematic will show that all of
the flip-flops and monostable multivibrators associated with the Examine
and Deposit functions will be disabled. The 'J' input of the flip-flops
need to be high, and the 'CLR' pin on the mono-multis need to be high
in order for the these specific panel functions to work.
Best regards,
Scott
Thanks for the info! that is basically what I was thinking, but I hadn't
forced the port speed and duplex yet. I turned some debugging features on
and see exactly what you were talking about !
Thanks

Subject: RE: VAX VMS Question
Yes. On the 2950, set the port to 10Mbps, half-duplex, no flow
control, no spanning tree:
int fastethernet 0/xxx
speed 10
duplex half
flow none
spanning-tree portfast
no shutdown
or somesuch. The Cisco ASIC's hate the VAX ethernet port, same
here on my 4000. Basically, the ether connection is bouncing
between between various modes, making it slow and such.

Ade et al,
Gotta cast another vote for the 4000 VLC. If you have room for a
laptop and an external CD, you probably have room for this VAX. And if you
use it to learn VMS, you can (when you can get an 8800, or whatever) charge
on ahead to a very asymmetric VAXCluster. Or use it to NetBoot the 8800,
etc.
I know a guy in Houston, TX who at last count had a "stack" of
those with 24M (max) RAM and hard drives with OVMS installed, and for which
he's trying to find good homes. I have not mentioned to him the possibility
of transatlantic shipping, but let me know if you are interested.
And, if you have a lot more money available: (just came up on
comp.sys.dec.micro)
http://www.aub.nl/vaxsales/
a 3100-85 for 600 (money units not specified)
a 3100-80 for 500
both for 1000. Each includes 3 VT510+keyboard. One includes a CD.

Last I checked, they removed all except for System 6.0.8 and System 7.5.3.
The do have updaters for most of the systems, but they are just updates
that need the original system to run.
Once upon a time their FTP site did have a number of the pre System 7
versions (not all, but a handful of assorted versions). But I don't think
they have ever had full installs of anything but System 7.5.3 in the 7.x
and up range (and 7.5.3 should REALLY be updated to 7.5.5 as soon as it
is installed... .3 has a ton of bugs in it that are fixed in .5). System
7 is when they went to a paid OS model, so they didn't give the stuff
away. 6 and under their policy was you should go to your local Apple
dealer with blank disks and they will give you the latest OS version (at
least that is what they told me when I asked once how to get an update to
6.x)

I found a Bernoulli Dual 20Z drive in a thrift shop.
Does anyone know anything about it?
It has a SCSI interface on it, but I don't even know
what capacity of disks it can handle, and where can
I find software to drive it.
They has some "90" disks there too, which do fit
into the drive, but I'd like more info on it than that.

I've come to the realization that top-posting is yet another sin that
Microsoft needs to answer for! In MS LookOut, it expects you to top-post to
replies (I suspect this is yet another MS ploy to waste disk space[1] as I've
also observed that people using MS LookOut tend to not know how to trim
messages[2]).
Zane
[1] Just how much Stock does Microsoft and it's employee's have in companies
that make Hard Drives? This is the only logical explaination for MS being
such a waste of disk space.
[2] Please note these observations are not targeted at anyone on this list,
as I've made the observations elsewhere.
John,

Yes, this is a DSSI drive. There is a SCSI version of it, the
TZ86, which basically includes the SCSI-to-DSSI board. I have
several TF85's of both types... very nice drives. The 86's and
87's are higher capacity- I believe *but am unsure* that the
87 is SCSI-only.

The "backend" part is hardly onerous, and the ability to do all sorts of
tricks makes it a pretty good macroassembler. As for relocation, that's
why you use both P% (program counter) and O% (where the code will be
assembled).
