I've been playing with the PDP-11 emulator some the last couple of days
under Linux (it's a lot quieter than the real thing), and am wondering
about having a second console. I see in the configuration that it has two
consoles, but I can't figure out how to access the second console. Any
ideas? Is it possible to hang a VT off the serial port and have the
emulator talk to that?

Like any other new processor. In fact, the microcode instructions
are nothing else than the 'real' instrructions of the CPU. And the
microcode of a CPU is nothing more than a basic, build in interpreter
for the 'official' instruction set. So the development is (almost)
the same as for any Interpreter you want to write fo a naked system.

Neither, you lucky dog! I have these cartridge adapter thingies that supposedly allow one or two Disk ][ drives to be used with it, but I don't think I ever managed to get it to read a disk (this is likely due to my ignorance, though none of this stuff was known-good when I got it). I may have a spare disk adapter -- you interested? There's also another cartridge-like adapter for a printer, and one more with another version of BASIC. I can check in my parts bin for spares if you want.

I hope you cannibalized one L3K to fix the other, and not to fix something

Yes, it donated some of its vital organs to save the life of the other one. ;)

I believe it is relevant to the list for people who might be in the area at
the time.
If I'm trveling to the bay area and see that there is a get-together going
on at the same time I would make sure to attend.
This invitation is not reserved to people living in the Twin-Cities but to
all and that includes travellers.
I used to do quite a bit of travel for work and had nothing to do with my
evenings. Sure the chances are slim but still it is worth the added
messages.
It sure beats IMHO discussiond about guns or other means of destruction.

Picked up a new stack of systems, one of which is an Ithica Intersystem
DPS-1. If you have ever seen one, it looks suspiciously like a PDP-11
console. Or at least it would if this one had its dress panel...
On the longshot front then, does anyone have a spare (extra, random,
looking for a home) front bezel for one of these units? Or even a (more or
less) complete chassis looking for a new home? It is also missing a couple
of switch levers. The nice bright orange ones.
This unit even has a bit of a history. Before it came to me it had been a
development system at Digital Research (yes, THAT one) In fact it came
along with a great deal of materials most of which have been forwarded
along to Tim Olmstead for addition to the CP/M Source Archives.
Apparently, they did not have much use for the dress panel on the machine
(hardware tinkering and such) and it had been lost for some time before the
machine came to me. (darn)
So... any help appreciated as always!

generally plastic is easier to work than metal. depending on the part
you can machine it out of a block of similar material. Used to make a

Well first off there are companies that if you supply the drawing and pay
dearly they will make the requested item.
I'd suspect the Gunsmith would possess the tools needed. It doesn't take
a larg machine shop to do many of the processes needed to make a firearm
same applies for computer.
A case can be made of easily machined plastics or even wood and painted
for protos. I made a system box years ago out of wood to simulated the
look and feel of a quality epoxy glass resin, no majik other than knowing
how.

> Oboyoboy! Do these folks have any Barrett Light Fifties?
I always wanted to try out a rifle that could remove a shooter's
shoes
for him! kaBLAMMMMM! ;]
Nope, out of luck, all they have are pistol and submachine guns, after
all, it's an indoor range, a .50 BMG would go right thru the wall and
the building next door too. Indoor ranges don't have the backstop for
any rifle rounds, so no AKs, FALs, Galils, any of the good stuff either.
BTW a friend of mine makes a printed circuit type card for a
computerized chronograph used to measure 20mm rounds for an ammo
manufacturer. They actually fire the round thru the card, and use the
break in the circuit to control the chronograph. Because of the size
and amount of gas generated by a 20mm round, a regular chronograph using
sky light doesn't work, not accurate enough. The card is actually silk
screened conductive ink on cardboard.
Yeah, I'd like to have a Barrett too, but $5K is a bit too steep for me,
unless someone would like to trade for a nice IMSAI with front panel?
Then there's the cost of dies and a reloader for .50BMG rounds...

>Sad. That was probably perpetrated by those Israeli guys in Las Vegas
who
rent out machine guns for an hour or whatnot so you can blast away at
stuff. I'm not kidding, this place exists. Northwest of the strip I
think.
There are at least two places west of the strip, Shooter Supply (the
nicest one) and The Survival Store, that rent out or sponsor machine gun
events. Both are close to my office. I think there are a couple more
on the east side of town. These ranges are very popular with Japanese
tourists. Typically they rent out Uzis, Thompsons, MACs, and the usual
generic batch of 9mms.
