And the Internet turned fifty last week

 

Hello!
Read this and react:

"
Depending on how you look at it, the Internet turned 50 years old last
week (
) . On October 29, 1969, the first message was transmitted between two
of the four nodes that made up ARPANET, the Internet's predecessor
network. ARPANET was created after a million dollars earmarked for
ballistic missile defense was diverted from the Advanced Research
Projects Agency budget to research packet-switched networks. It's said
that ARPANET was designed to survive a nuclear war; there's plenty of
debate about whether that was a specific design goal, but if it was,
it certainly didn't look promising out of the gate, since the system
crashed after only two characters of the first message were sent. So
happy birthday, Internet, and congratulations: you're now old enough
to start getting junk mail from the AARP ( ) ."

Drew,

Well I arrived at SP4. The VM Share archives have the summary from some off the release notes which largely agree¡­.

A short VM/SP history summary:

    • Full Screen CMS
  • VM/SP 6
    • Shared File System (SFS)

Thus, the LCM+L 4361 running VM/SP 5 has all of the above except SFS.

I think the primary reason for GCS's existence was to support running VTAM natively on VM/SP; previously it had to be in a guest machine such as VS/1.

By VM/SP 4 IBM had a revised version of the RSCS Program Product running under GCS.? It also had TCP/IP (running on CMS). The 4361 doesn't have either installed (they do have the media) because of a lack of the associated hardware.

Timothy,

I am not sure when XEDIT appeared, SP1 I think or REXX . Whilst folks have written a screen mode editor and installed a portable REXX on VM//370 they don¡¯t interact in the same way that XEDIT and REXX do on VM/SP which means many things don¡¯t work.

?

Also note XA mode isn¡¯t virtualizable in the same way that 370 mode is.? VM/370 relies on the fact that the Store PSW is a privileged instructions so that a user mode program can¡¯t tell it¡¯s a use mode program.

Some of the instructions introduced in XA mode expose the machines state back to a user mode program. This means you can¡¯t use the same trick. XA mode also introduced a new instruction called ¡°SIE¡± which stands for ¡°Start Interpretive Execution¡±. This means tweaking VM for XA mode isn¡¯t easy¡­. Much simpler to run LINUX barefoot..

Thanks. I did not know that VM/370 do not have XEDIT.? XEDIT appears in VM/SP Rel 5 or before so that I think.

?

I looked at ESA IO and S370 IO instructions on Hercules sources? Both IO mode can coexist together so that it is possible to rewrite CP (VM hypervisor) easy. ?I have to take a look on CP sources on VM six pack distro. Also can extend DAT management to allow paged memory space in 31-bit mode.

Well, licensed code is not needed.? So can port open-source MSYS into VM/370 for POSIX shell and implement BFS specification like unix filesystem. ?I am looking for BFS specifications. ??POSIX shell and BFS first appears in VM/ESA and later.

Thanks but I already read that. I was able use PF and PA keys on x3270 and Vista TN3270 that I purchased for $30.

?

When it displayed ¡°HOLDING¡± or ¡°MORE¡­¡±, I just press PA2 to continue (ctrl-home on Vista TN3270 or Alt-2 on x3270).

?

Also I use PA7 and PA8 to scroll text information up and down.

?

I learned new thing about dirname like ¡®A¡¯, ¡®S¡¯ and ¡®Y¡¯.? Same way like much ¡°C:\¡±, ¡°S:\¡±, etc.

?

Example: LIST fn fe fm where fn = filename, fe = file extension, fm = file mode or dirname

?

List * * A to see user directory

List * * D to see games directory

List * * S to see system directory

List * * Y to see installed software

?

Tim,

VM/380 mode simply allows access to more than 16Mbytes of memory. The memory above the ¡°line¡± is real, non-paged memory, so must be shared among all VMs that use it.

It does not implement XA or ESA mode IO so you can¡¯t IPL a LINUIX system. That would really need a major re-write of CP the VM hypervisor. I can¡¯t see it happening.

You can IPL LINUX directly under Hercules though,

The POSIIX shell is licenced code so I can¡¯t see how it could run without a licence.

There isn¡¯t even XEDIT in VM/370R6 (the release go R1->R6, SP1-SP6, XA SF, XA SP, ESA) so R6 is something like 10 release behind VM/370R6

Re: Listserv, Relay, Xyzzy and TCP/IP.

 

From the original author of the Pascal version of Relay:
Between VT moving away from VM/XA as part of Y2K and the demise of
Bitnet, it's been a long time since I've been sure I knew where the
RELAY source was. Even if I had a copy, he'd need a legal copy of
the Pascal/VS compiler to build it (I used that because Clarkson had
a license for it, and the licensing on the runtime allowed me to
ship a
RELAYV2 MODULE that had the runtime linked in. The C compilers for
VM didn't allow that.) I admit being surprised that anybody still
has an RSCS network large enough to make running RELAY worthwhile.
Also, unless he has a VM system that does IUCV, the Relay code won't work.
And if we're talking VM/370 R6 that won't fly. If he's on VM/SP R6
that would be a different story.
Someone is working on RSCS and IUCV for VM/370 R6. I have good
knowledge of pascal language so that I can port that to other modern C language.

There are many IRCD source codes on github and others for Internet.

Does anyone have any copy of Relay V1 (REXX version)? I know that
Relay V2 is Pascal version. I used Relay on BITNET while I was student at University.
I had not heard any replies yet that I recently asked for.

Good news! Standard pascal compiler supports Pascal/VS as compatible so that Relay V2 pascal files can be compiled into module files.

Who is author of Relay V2 so that I need to contact?

I have Xyzzy chat programs but no original source elsewhere. I lost them (includes source codes) to drive failure. I need to contact author to get another copy. I can't find him through Internet so far.

Thanks,
Tim
