Hi all
Got word from Steve Davidson in NH (USA) that he is without Internet access most likely due to what is left of Sandy. He'll advise when he's back on the "air".

Lets call it for what it is - "legacy" is a term that people use in a
polite but derogatory manner to imply that the future direction they
prefer is not that which they view as the current direction.

I had a PDT-11/150 many years ago, mid-80s. It was kinda fun, but
also kinda pointless. The only thing you can run on it is RT-11.
I had one too back then and had a blast! RT-11 is terrific (infinitely
better than contemporary microcomputer OSes), and anyway a 150 will run
pretty much anything an 11/03 will run (but with 30 KW of memory instead of
just 28) so it's really pretty flexible. I wrote a FORTH-79 system on mine
(including a stand-alone 4-user version with a blinky NULJOB display on the
two LEDs), and a PDP-8 cross-assembler, and one side of a two-user "pong"
game that worked over the modem, and ported Small-C to it, and did a zillion
other things I don't even remember. Something or other with a Microsoft
serial mouse plugged into the modem port? It was such a great machine!!!

Hello!
Actually, Dave, and you too John, those are two of many reasons why
I'd give one of my lives for finding one of those things. I naturally
have other reasons that're too numerous to mention. In fact I have to
updated my website at http://www.gregg.levine,name which insists that
on the equipment wanted page its just the PDP-11/23 and the PDP-11/53
who're wearing those interesting features, to now include one of those
little devils.
For example Dave if you come across the guts to actually build one of
the PDT-11/150 and such like but have nothing for it to do then I'll
be glad to accept it, of course there are other issues a foot.

Has anyone actually managed to get this to work (i.e. RSTS/E
+ DECNET 4.1)? :)

I'm kinda shocked to see that you wouldn't be able to run NetBSD
/on/ a VT180 ;)
Z80...no MMU, 16-bit address space
Ah, right. I keep forgetting how old the Z80 actually is and the fact
it doesn't offer too much in the way of anything beyond small
embedded stuff now.
And lots of VERY enjoyable retrocomputing.
Hmmm, I've been reminded of that project someone accomplished once:
simh + a phone + a vt100. But instead someone could go: simh +
raspberry pi + VT180 ;). Hide the pi within the cabinet, implement a
little piece of software to go between simh and a real serial
interface (or can simh interface directly now?) and run VMS "in" a
VT180.
That's certainly doable. With most any of the VT family, I'd say.
Was CP/M in ROM on the VT180?
Nope, booted from 5.25" floppy from an RX180 disk subsystem.
You'll be able to see one when you come visit, though I can't find
the floppy cable.
Aww, shame you can't find the cable. :(
Yeah. I have the pinout, and it's DC37<->DC37, which I should have
some of somewhere, so I will make one if it comes down to that.

I have a feeling you'd want something more valuable than an iPad

Perhaps not...are you looking to unload the iPad? I'd hook you up
with a sweet system for that.
Yeah, I'll part with the iPad. Don't have much use for it now save
for as a musical instrument. I can include 2 keyboards, one docked
and one Bluetooth. 2 cases as well, keyboard is built in to one of
them. Wall charger and sync cable included. Hell, I still have the
box...
Hmmm. Ok. Let's take this off-list. (tomorrow...about to crash here)
Yeah, okay. Tomorrow.

Have any interest in a USB/eSATA SATA drive dock?
Nope.
Unfortunately, all that remains is the keyboard and processor. And 6G
of laptop DDR3. It was a fairly broken laptop. I /might/ still have
the display, too.
That's, umm, not terribly useful. ;) What happened to it??
It had several issues. The power system was touchy...it would be fine for months, then it would sometimes endlessly turn itself on and off (for a better description I'd need to consult logs...it's been awhile), graphics would glitch, disc drive loved oftentimes not working, it couldn't boot from USB CDROM. It couldn't do hardware-assisted virt, the NIC might not have been GigE, short battery life. It wasn't very old either...
Even more amusing? It was a product model that did not exist. The model did not appear on the manufacturer's website.
So I scrapped it for useful parts.

You like CP/M machines because they ROCK. That's all there is to it. ;)

You can alternatively look for a VT103 as well, since that is pretty
much the same thing as a PDT-11/130.
If you do some wiring on the Qbus backplane, you can do 22-bit. Throw in
an 11/93 CPU, SCSI and what else, and you'll have an awesome system in a
VT100 body.
This is probably a better idea, but it will likely need some
beefing-up of the power supply. The power supply in a VT103 is a bit
underpowered for bigger hardware. It can be done, though.

I've got an Intertec Superbrain sitting around on my desk in London but no software for it - that'd make a pretty nifty OPA0 too I think.
I think the drives are fubar'd though and they're some weird quad density format, so I thought I'd _carefully_ disassemble the machine and put like a modern machine into the casing, booting into some souped up CP/M emulation thingie...
