I'm already up to the ceiling, check out the picture on my home page:
http://people.mn.mediaone.net/fauradon/index.html
On top of that I have the laundry room wall (the one without the appliances)
loaded up from floor to ceiling.
At this point I have exhausted all storage solutions for in house storage
and I can't even get to the far end of my office without planning the trip
at least a week in advance :)
Right now the only choice is OUT. That means the shed or a rental space.
I would much prefer the shed.
Thanks

Almost as difficult question as "What is the meaning of life".
The answer just came to me: "To be the winner of the contest: He who
dies with the most 'puters wins."
My latest haul included over 100 machines of the same brand. I had to
rent a space at a local U-Store-It place. I must be crazy. More on
this haul later.

Up to now my collecting has been pretty much DEC stuff and a few
odd Intel boxes. So I guess you could say we suffer from the same
form of insanity.
Idea, contest time! We need a name for the form of insanity whereby
you continue to haul home DEC.

It was more of a rescue than looking for satisfaction. I kept them

Point taken, and understood.

Greetings and salutations;
We're in the process of upgrading our mailservers, including the one that
hosts the classiccmp mailing list. We're building a new machine with a newer
version of the OS (FreeBSD 4.1), and a newer version of majordomo (1.94.5),
and then moving the services off the old one and onto the new one. Once
done, the hostname, ip address, and all identity of the old machine will be
taken over by the new machine (ie. no differences [we hope]).
We will do our best to ensure there are no service interruptions, but the
following issues are possible:
1) There may be some delays in list traffic during the upgrade
2) Once moved to the new system there may be some "features" that need to be
worked out
3) There may be delays in updating the mailing list archives at
www.classiccmp.org during the transition
Please email me with any problems you may notice to both jlwest(a)tseinc.com
and west(a)tseinc.com
Thanks!
Jay West
OK, I have my Microvax II KA-630 (thanks Carlos) and I now need to
completely understand it. I have discovered the follow boards are in
it:
KA-630 (CPU w/FPU and 1 Meg RAM)
Nemonix NXII-16 (half filled, Meg of RAM)
M7608 RAM (4Meg I think)
M7516 (DELQA Ethernet adapter)
M7555 (2x MFM Disk controller)
SI Part # 981-4617 (ESDI board? SCD-RQD11/EC)
RCI - Recognition Concepts INC. NO 100220 - Has a TRW 1007J1C3 8451/AP
(Analog?)
M5976-SA KZQSA (SCSI)
Ok this machine has 1 MFM drive (~50M) and another drive (which I haven't
kooed up yet). I hope to build the IDE interface in the next few months
to save money on the drives. I can get a 760M ESDI drive for ~$300(US).
Now the SCSI is borrowed from a BA213 (hence the SA) I intend on knocking
out the rivets and making it usable in both machines. I may also upgrade
the Nemonix to 15M to get a full 16M. I already have 3 2.5G SCSI (and a 9G
SCSI-3 drive, yea I know ...).
Does anyone recognize the SI board or the RCI board? What is the minimum
size drive for loading VMS 7.2? Any other thoughts? My fingers are itching
to learn VMS?
One other question, what command do I need to remount the drives on a
Microvax II? My machines go off line and I don't know what commands to
type to get them back.
Thanks.

Oh holy bat guano, Eric... nice rescue! When was the last time it
was operational?
Somewhere, I may still have the Macro-10 source code for RWATCH,
a superuser hack that floated around the University of Louisville
for years.

I vote to drop-kick this weeks discussion/useless rant on Windows and
other OS's and other pokes to list members.
Get back to you classic computers, VAXen, boxen, whatever-you-have-en,
which this list is meant for!
Anyone with me on this?

Darn, don't you just hate when we get into a size enumeration contest.
Remember what they say "Size doesn't matter."
Actually Eric, I had to rent the storage space, the three car garage
which also contains two other rooms 8x20 & 8x10, and a good size loft
were already full. And although there is still room in the 30x40 barn
with its loft, I only use it for the stuff that is probably destined
for the recyclers/scrappers.
I would like to have had it closer so I could test this stuff easier,
but had no choice.

Thank you, Gary. You need not look farther than Iowa to find words
of wisdom and the good side of the situation. If only my SO could
see the silver lining. ;-)

Info on the MMJ connector found on various DEC terminals & computers.
--------------- --------------- --------------- ---------------
---------------
DEC uses an MMJ (Modified Modular Jack) connector on its equipment for serial
data communications. DEC calls the mating plug on the cable an MMP
(Modified Modular Plug), only the term is not used as often and most of the
time is just simply referred to as MMJ. It is like a modular telephone
connector, only the key on the connector is offset, not in the center like
a standard telco connector.
Looking at the back of a VT320 for example the MMJ looks something like this.
--------------------
| * * * * * * |
-------------- --
|____|
1 2 3 4 5 6 are the pinout numbers
--------------- --------------- --------------- ---------------
---------------
The signals are:
# I/0 Desc
1 > DTR Data Terminal Ready
2 > TXD Transmit Data
3 - TXD- (ie Gnd)
4 - RXD- (ie Gnd)
5 < RXD Receive Data
6 < DSR Data Set Ready
> = terminal or computer output signal
< = terminal or computer input signal
--------------- --------------- --------------- ---------------
---------------
DEC's part number for the cable is BC16E-xx, with the xx being
the length. The cable is made so that the connector on one end is
mounted 'right side up' and the other end 'upside down'. In other
words, the key tabs on the connector are on opposite sides of the
flat cable.
//
---- ----
| |---------------------------------------| |

That is effect causes the signal lines to cross-connect or as I like
to say 'turn over' from one end to the other.

I had a DEC MMP cable that someone cut one end off so I wired it to a female
9-pin D connector to use with a PC 9-pin serial port. Wired as follows:
MMJ DE9
1 6
2 2
3 5
4 5
5 3
6 4
This was to use a PC as the console on a DECsystem 5500 and/or one of the
ports on a DECstation 3100. I actually did not connect DE9-6 to MMJ-1.
It worked fine without it. I later made a breakout box with two 9 pin
D connectors and an MMJ socket along with the means to disconnect and
rewire as needed. I found that it works fine without DE9-4 being wired
to MMJ-6. In other words, using only the two data lines and ground.
Your mileage may vary, depending on how things are setup.
--------------- --------------- --------------- ---------------
---------------
DEC makes several adapters to adapt the MMJ to 9/25-pin D connectors.
The H8571-A and H8575-A are MMJ to DB25 (female) and are wired as follows:
MMJ DB25
1 20
2 2
3 7
4 7
5 3
6 6 & 8
Also pins 4 & 5 of the DB25 are tied together
I have used the above using a standard DEC BC16E cable to connect to
a PC 25-pin serial port to use the PC as a terminal.
---------------
The H8571-C and H8571-F are MMJ to DB25 (male) and are wired as follows:
MMJ DB25
1 6
2 3
3 7
4 7
5 2
6 20
---------------
The H8571-B an MMJ to DE9 (female) and is supposedly wired as follows:
MMJ DE9
1 5
2 2
3 7
4 7
5 3
6 6 & maybe 8 (depending on which DEC manual you read)
I have never seen one, so have not actually checked how it is wired.
It should be noted that this is not wired correctly for PC 9-pin
serial ports, besides the gender of the 9-pin connector is wrong.
DEC says that this is used for connecting to 9-pin printer ports.
--------------- --------------- --------------- ---------------

And here is a summary on how the various signal lines match up to
each other on the different connectors.
