I have two VAX machines here running VMS under the hobbyist program; it's
been a whlie since I messed with OpenVMS seriously and in my haste to get
going, I foolishly installed DECnet Plus rather than DECnet Phase IV.
Now I have a two-node cluster, but the nodes don't seem to be aware of each
other outside of "SHOW CLUSTER". I can't perform network operations
including PHONE, SET HOST, etc. It just always tells me that "the remote
node is not currently reachable".
Is there a quick way I can uninstall DECnet Plus and replace with Phase IV
without having to take all the time out to reload both of these machines
>from scratch? I know there's gotta be at least a few folks on here that are
conversant in VMS :)
thanks for the answer, my comments inline:

They are in fact Century Data T80 (80 MB) but the MAI manual states 20MB
? I have scanned the service manual, this as well as the manual from
Century Data is available on bitsavers

I will take more photos when the machine is here, may take 2 weeks
because i will be vacation for a few days.

At least the schematics of the 200/410 32K memory board shows -5 V (on
page 6.73) connected to the memory IC's. They are shown as 2107B, have
not yet found a datasheet for these.
Both machines are from around 1980 so they should be similar, when not
identical. The larger machine has another disk controller containing an
additional CPU, will see if the large one arrives.

That would help, thanks.

Thre is not much information available for these machine, i have started
some small description some years ago (http://www.ardiehl.de/basicfour),
maybe i can add some information you provide.

yesterday i got a complete MAI Basic Four 510, similar to the 610/730
including 2 14" removable disk drives including a lot of disk packs. Due
to the size i have yet transported one drive, the printer, terminals,
disk packs and the documentation only. I have to pick up the CPU, the
2nd drive and the remaining stuff over the next weeks.
Now i'm looking for the service manual since there seems to be a defect
in the cpu power supply, the main fuse is blowed:
M8001XX System 610/730 Service Manual
Anyone out there having these or similar manuals ?
These ones would also be very interesting:
M80651A System 1350 Service Manual, Vol I
M80652A System 1350 Service Manual, Vol II
M80781A System 1600 Service Manual, Vol I
M80782A System 1600 Service Manual, Vol II
The new ones i got (Disk service manual and owners manual for the
610/730) will be scanned and send to Al within the next weeks.

I have a Northstar Horizon that almost has a buyer and I would like to
send him some disks to use with it. Would one of you Northstar users
please contact me privately? I would like to get boot media and some
spare hard sectored disks.

A: Because it fouls the order in which people normally read text.
Q: Why is top-posting such a bad thing?
Q: What is the most annoying thing in e-mail?
A few of you may recall that I was, some years ago, working on a KA630
emulator and was stuck getting the ROM code to like the console SLU.
(I want to eventually get it to the point of running NetBSD/vax and
possibly other VAX OSes.)
I now have it passing POST! It gets to the point of
Performing normal system tests.
It can't go any further yet, both because I haven't implemented any
potentially bootable peripherals and because I haven't implemented
console serial input (and thus can't type any commands at the prompt).
But, progress is being made!

Hopefully someone can save this from some horrible "steampunk" fate.
Way too nice for that. Hopefully the price will keep it from such a fate.
Delurking for a brief announcement:
I was recently contacted by an individual whose deceased relative was a
long-time computer professional, as well as hobbyist.
The individual asked me to help disseminate the bulk of the relative?s
collection, which numbers in the hundreds of items, including CPUs,
software, documentation and associated peripherals.
I've been helping the individual catalog and list everything. A small
sampling of the items:
a Hero Jr. robot
an AT&T PC that she describes as a "UNIX computer"
stuff from Cromemco, Apple, Wang, Microsoft, DEC (manuals only), Tandy,
Texas Instruments, etc.
I know this isn't very specific, but there's too much to list here
Here's a link to a Microsoft Word document on my Dropbox of everything
available. The individual is looking to sell, rather than donate:
Please contact me off list and I'll put you in touch with the seller and
you can negotiate privately.

I figured out how to extract the drives. The chassis is not designed to
make it easy; you have to remove the key switch and "Quay" faceplate, which
extends downward just enough to block sliding the drive out the front.
Both drives are the 77618022 variant, with PWA (PCB) P/N 77615454, which is
not described in the manual. It has a few less ICs and several more
potentiometers than the PWAs in the manual.
The drives appear to have been manufactured in late 1979, so it seems odd
that they wouldn't be in the mid-1982 9406 manual.
