Gentlemen, I was playing with MS Kermit 3.15 today (don't ask), and discovered it supports a rather amazing number of networking protocols including DECNET and something called "SuperLAT" - anyone have any experience of connecting to a DECNET host or LAT host with this?

Subject: [rescue] PDP flip chips and memory boards, many lbs. worth
Reply-To: The Rescue List <rescue at sunhelp.org>
Some of you here know that I recycle old PC motherboards, etc. though
whenever possible I try to divert anything valuable/historical out of
the melt-it-down pile.
I have many pounds, well over 100lbs., of DEC PDP "flip chip" modules.
I have to charge for them, but would like to sell all of them, all at
once, to 1 person if possible, at a per-lb price ($8 per lb). Given
that these flip chip modules are not very heavy this works out to well
under $2 each, I think.
Some are in original plastic shrink wrap, but most are not, and have
been exposed to moisture but are otherwise complete; some have had the
resistors or capacitors on them "weep" which means they would have to be
replaced by someone competent with a soldering iron.
A random listing of the few that I pulled out:
A123
A206
A207
G728
K012
K026
K028
K123
K124
K134
K161
K202
K210
K303
K683
M113
M1502
M155
M207
M230
M502
M652
M7264
M783
M7941
M920
M974
There are many more.
Are there any PDP collectors on this list - I know there used to be but
perhaps this stuff is just too old these days.

This is why I like HECNET - instant answers to esoteric questions :)
Which reminds me - anyone have any tips on how to get remote XDM going on OpenVMS VAX 7.3? I can't find the setup files.
Basically, I want to point an XDM client on the laptop at the XDM server on the SIMH machine and get a graphical session that way.
Sampsa
Might this be what you're looking for sir:
http://lakesdev.blogspot.com/2008/09/running-remote-openvms-cde-desktop.html
Perhaps. Run @sys$manager:tcpip$configure
Select server options, the last one ought to be xdm. Its state must be enabled, it is probably disabled or stopped. Once you disable a service all files get deleted.
This all off the top of memoryn I have no access to my own systems now so i can't check all this.

No CHIMPY is a physical AlphaServer 800, and VMS on it recognised the memory upgrade automagically.

DELLVX is the emulated contraption - I wanted to be able to talk from the main host machine to the SIMH box, so I run SIMH in a VM on the main host, viz:
DELLHOST - Physical Dell laptop, running Ubuntu Desktop 10.04), runs Oracle VirtualBox:
DELLVM - Virtualised Oracle VirtualBox VM running Ubuntu Server 10.04, runs SIMH:
DELLVX - Emulated VAX running OpenVMS 7.3
This way I can connect from DELLHOST to DELLVX by network, the DELLVM is quite lightweight as it runs Ubuntu Server (like 30-40 megs overhead).

That's a difference between alpha and vax vms, on alpha physical_pages is not required.
I can't remember. Is there some other parameter that do the same thing on the Alpha, or will it dynamically detect and manage this on boot?
About 7.3-1, yes that is obviously a type since there is no such vms version for neither vax nor ia64.
Thanks. I was wondering if I had missed something.
The last vaxes, the 7000 and 10000 series supported 4 GB physical memory. I wasn't aware of more than 32 address bits in the hardware.
Well, earlier VAXen only support 30 physical address bits. The NVAX supports either 30 or 34 physical address bits (software selectable which mode it should operate in). How many address pins actually were brought out from the CPU chip, as well as out from the CPU card, I don't know, which is why I said "in theory".
It might be that the 7000 and 10000 only supported a max of 4 GB, but that would be a restriction of the physical design in that case. The extension of the VAX MMU done for the NVAX brought the size of an address up to 34 bits.

The address field in a PTE can be either 21 bits (traditional) or 25 bits (extended). Add to that, the address within the page (9 bits), and you'll end up with either 30 bits, or 34 bits of physical addresses.
32 bit physical addresses have never existed on a VAX.

As for memory, VMS (on VAX) supports up to (in theory atleast) 16G of
physical memory. However, that requires the extended memory mode PTEs,
which only came with NVAX, so no luck with simh.
The "older" layout supports a max of 1G, but I think all architectures
machines split that into 512M of RAM and 512M for I/O space.
Oh, and when you add memory, you need to run an AUTOGEN afterwards, to
change a bunch of parameters to the new hardware config (whould be
obvious ;-) ).

That is one of the things AUTOGEN will do for you, yes. :-)
As always, you do not need to run AUTOGEN, you can always trim the parameters yourself if you want to. After all, that is all that AUTOGEN do as well.

Well, I didn't write 7.3-1, I asked if it really was correct that Sampsa was using it, as I believe 7.3 was the last release for VAX. :-)
And I said "in theory", since I'm not sure any existing VAX ever brought out all 34 address bits, but there are really 34 physical address bits in the VAX extended addressing mode. Check the spec.
The address field in a PTE can be either 21 bits (traditional) or 25 bits (extended). Add to that, the address within the page (9 bits), and you'll end up with either 30 bits, or 34 bits of physical addresses.
32 bit physical addresses have never existed on a VAX.

The last release for VAX was 7.3. Anything later is alpha or ia64. 7.3-1 was only released for alpha.
The address space for VAX is 32 bits, no page bits. And 2**32 is 4G. Where did you find 16 GB?

As for memory, VMS (on VAX) supports up to (in theory atleast) 16G of
physical memory. However, that requires the extended memory mode PTEs,
which only came with NVAX, so no luck with simh.
The "older" layout supports a max of 1G, but I think all architectures
machines split that into 512M of RAM and 512M for I/O space.
Oh, and when you add memory, you need to run an AUTOGEN afterwards, to
change a bunch of parameters to the new hardware config (whould be
obvious ;-) ).

Hello!
I believe you are right. Sampsa, what in the Name of the Force, and
the fellows who mind Time, are you running VMS under? Simh was ported
to Alpha, it's not happy there, but it works.
And I do recall a reference to an Alpha emulator, its only problem was
one of scarcity. No not the one you told us about not too long ago, a
different one.

Yes they are, but I don't have the coding skills or time to develop a JIT for it :)

If I had the code-fu, I'd love to write a JIT for SIMH, imagine the performance we could get out of it with that...

Sampsa,
What kind of a laptop and what OS are you running? The 3900 series systems ran about 38 VUPs and the 780 ran at 1 VUP...

Cool, I now have a 14 VUPS laptop with 512 megs of RAM. Just trying to get DECWINDOWS to work, I'm assuming I can get it to display remotely even though it has no graphics hardware built in, right?

Try modifying PHYSICAL_PAGES, perhaps the microcode that comes with simh was modified.
