Hi,
For quite some time I've been pondering getting either a PDP or a VAX, I'm
wondering about a few things. First and formost would be how does one go
about finding one :^) and what kind of price can I expect?
Also, what would space and power requirements be? Yes, I'm aware they vary
in size from tiny little things, up to systems that require a full sized
computer floor. I'm thinking a system that would fit in a garage as far a
size goes.
Also what would be a good source to familiarize myself with the various
models as I embark upon my latest quest?
Thanks,
Zane

Anyone ever run STiK on an ATARI ST? I have it up and it works, but I
can't seem to get a DNS resolution, If i manually put in IP's its works and
connects, say to IRC. But I can't get it to resolve names against IP's I
have the entries in Default.cfg that the docs SAY that works, but it dosn't
appear to.
Line is NAMESERVER x.x.x.x
and NAMESERVER0 x.x.x.x
obviously, in my configuration I have the ip's for our nameservers.

There was a game called "Night Driver" that was similar. It too was simple
graphically, with a pair of dotted(?) lines scrolling downward to indicate
the edge of the road. It would bend right and left -- curves -- and you had
to steer between them. Had a real steering wheel and an accellerator pedal,
possibly a high-low gear shift as well. I know there was a sit-down model,
there may have been a stand-up version as well.
It was incredibly simple, especially compared to some of the high-end,
need-a-pentium-and-3d-video-card games out today, but it was actually a lot
of fun.

<No, not really. I just call up California Digital (310-217-0500,

There is that. Myself I only have two sets of 8" to worry about one sa800
on the cp/m crate (rarely used and that drive is generally powered off)
and my RX02s. Around here 02s are easy to find and I have spares for
everything on it. I also hardly use that, noisy, I have hard drives,
rx50 and rx33 as well. It's there for compatability.
Nearly every system I have has been migrated toward 3.5" drives or up
scaled 5.25s where possible. Exceptions are the Vt180 where compatability
is required and the odd 360k floating around. The PDP-11 and vax DEC
hardware it's not a choice for the most part and I keep them compatable.
Three goals are accomplished, single 3.5" media, more storage than 8 or 5"
formats and power down with media in place is not problematic. All 3.5"
PC/PS2 compatable drives have write interlock on power fail.
One unique thing I've done is to embed two PS2 720k 3.5" floppies inside a
kaypro as 782k hard disks. They are drives A: and B:. They have power fail
but, their bezels are specific to the IBM case. They can be found
real cheap as a result and are a deal. Using Advent turborom in the
5.25/96tpi mode puts 781k on them. By putting them on a bracket inside the
case they are captive and amount to a slow small hard disk from the user
side. For CP/M use 1.5m of on line storage not including the 3.5<782k> and
360k 5.25 on the front pannel makes for a fairly roomy system. That system
has a 2meg ramdisk so it can boot and copy the floppies to ramdisk for
speed. Advantages include if the media fails pop the cover and put in a new
disk and it's less likely to crash the disk if dropped.
The only other storage I keep around is the TU58 dectapeII as it's serial
and can be plugged into anything that can do RS232/423. At 256k a cart its
not big or fast.
What I'd like to find out how to do is use the floppy interfaced tapes
for non-PC systems. These drives in the smaller storage sizes can be found
cheap and even new ones aren't too expensive.

Ah. Yes, we used to call the 50-pin version a telephone or telco
connector because, well, that's where we used to find most of them:
going to a 5-line office phone, or on the side of a punch-block.
But HP-IB and Centronics printer connectors didn't have enough pins to
be called telco connectors. Besides, HP-IB used bigger, stackable
screws, and Centronics printer connectors had those ears. It wasn't
'til I saw the 50-pin Centronicsish SCSI connector that I started to
get confused.

Since no-one seems to have answered this, I shall put my bit in. I am no
PDP expert, though.

The 11/15 and 11/20 were two variants of the original PDP11 CPU, which
came out in 1970 (I think). The processor itself may have been called
the KA11, but I am not sure of this. The difference between them was
system configuration, AFAIK.

PDP 11/10 is usually an 11/05 variant (again the difference is
configuration of the system), dating from c. 1974 (and full of TTL -
74XX device codes and 74XX date codes can be very confusing). But I
have heard rumours of an 11/15 variant of that name. No doubt Allison,
Tim or Tony will tell you all about this. One day I shall get my 11/10
working...

AFAIK it will require a current loop interface. Some quite late
terminals had this feature - I use something called a Westward Graphics
Terminal.
