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.

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).

I was wondering about excess pressure the other day. I thought about a
pressure switch to shut off the motor, but they seem to be quite expensive.
Or am I just looking in the wrong places? Does anyone know where I could
get a pressure switch suitable for about 120 psi, cheaply?

Is it a screw fitting? Take it apart and wind 4"-6" of PTFE tape round it
the male fitting. You can get the tape from any place that sells air
accessories or vacuum pumps, or most plumbers suppliers.

!! RED ALERT !!
If you do not have the drive hardware (and computer),
you *cannot* erase the disk packs without rendering them worthless!
Bulk erase will destroy the data *AND* the servo tracks!
If you do bulk erase the disk packs, you can safely throw
them away because most of us (all?) do not have the equipment
to rewrite the servo track information.
BTW. I would like an other RM03 disk pack. I have got only a few
of those. I hope to spin up my RM03 in a few months; spare
fuses are standing by ...

Hi all,
I've just downloaded three assemblers from the ROM archive at
http://bbc.nvg.org . Catch is, none of them include manuals. I've got copies
of:
VASM65 v2.0E by Vida Rebus
ASM 1.10 by SYSTEM (claims to be the "ASM 6502 Macro assembler V1.10",
"Copyright (C) 1984 SYSTEM"). Contains text strings like "Press play", so
may be a tape->ROM conversion.
ROMAS 3.02 by TBK Associates (full copyright string = "ROMAS 3.02
(C)1985 TBK Associates - S.C."
Has anyone here got any documentation for these assemblers? I'd like to
get at least one of them to assemble *something*. Perhaps a "Hello World"
program?
Also, Vasm outputs Intel Hex files from what I can gather - does anyone
here have an Intel Hex -> Binary converter for the BBC Micro?
Finally, does anyone know how some discs were formatted so they were
compatible with 40-track and 80-track disc drives?
Thanks.

Does anyone have a VAX running VMS connected via ethernet to a Cisco 2950
series switch? I have had the VAX connected to a 2900XL series switch for a
year with no problem, but in doing upgrades, moving it to the 2950 has
caused major character delays, and other problems between the VAX and
clients connecting to it. Everything else connected to the switch is working
fine.
Thanks

If you want the flexibility of a "hotmail" ((I do, and I have it), but don't
want all the animated ads, get a bundle pack like Norton Internet Security.
I don't work for 'em, and I've only recently started using the package, but
it has a WONDERFUL ad-ware blocker that leaves your viewed web page intact,
while simply screening the ad location (turning it black or transparent). I
paid $29.95 for my copy, including a 1-year subscription to NAV's virus
updates, on the website: NextAisle.
Also, there's a couple of freebie packages available on C|Net's
Download.com: "Adware," whick you can use to clean your system and registry
of cached ad files, and "Pop-up Stopper," which does exactly what it says it
does. Both occationally leave you with WIndows Message Service error
messages (Of course! Your Adware thinks its broken if it can't cover your
screen with its ad!), but these are background, and much easier to dump than
the ads themselves.

Hello everybody, this is something I've been wondering about for some time
now. Perhaps here is the place to ask, since it's about one of the "inner
secrets of silicon":

If in fact the same die was used in both components, then it's only the
plastic (which is impenetrable to the commonly-used ultra-violet light) that
prevents the OTP variant from being erased and reprogrammed.
However, there are kinds of radiation similar to light which *will*
penetrate the plastic housing...you see where this goes? Will the memory be erased
when you, say, X-ray the OTP component, will it stay unaffected, or is the
thing just going to die?
(just outta curiosity)

Apple distributed the OS free to all up to 7.5x. Probably 7.55 is the
highest you should go on a Plus anyway with its limited RAM capabilities,
and if you don't really need OS 7.xx stick with 6.08 which is more spry on a
machine as old and slow as a Plus.
