Is there a difference between a DecStation 3100 and a VaxStation 3100? I
saw some of each today at one of my favorite money pits (escaped for under
$200 today!). Are they Vaxen or something else? I'm not too interested
(I'm an HP 3000 guy).
Anyway, the place I saw them is called HMR Global Recycling. They
basically take a *HUGE* warehouse full of old PC's and Macs and ship them
overseas everyday. But they also sell some stuff to the average joe. It's
mostly as-is, especially for the odder stuff. They have the DEC stuff,
plus some Sparc stuff, misc. Apple (mostly mac) stuff, and the occassional
wierd thing.
Sometimes they have good prices, and sometimes they don't; it depends on
who you talk to and how they're feeling. You go in, look around for what
you want, then find someone to tell you how much they want for it. There
is no set pricing, or anything, they seem to make it up as you go. They're
open to negotiation; I am generally able to talk them down a bit.
Anyway, today I picked up:
4 DB25-Cen50 SCSI Cables (HP) $2.50 ea
5 Mac Mice $6.00 ea
10 Mac Appletalk kits MIB $2.50 ea
4 250MB 3.5" SCSI HD's $17.50 ea
1 6 HH drive ext SCSI case $20.00
1 HP 9114 disk drive $10.00
and the best of the bunch...
1 GRiD Compass 1101 $15.00
Anyway they have a web page (not much, last time I checked) at
<http://www.hmr-usa.com/>, and they're located on 23rd St., just East of
3rd, near Army (or Ceasar Chavez for the tourists.)

Being one of the first generation hackers...
Some of my better hacks was blueboxing and using it to call MITS about
hardware bugs. The college dorm pay phone that always gave money back
(the trick was truly hiding the diodes used so TPC didn't find them
easily). Running a VLF (160khz) site, using FM on CB in the early 70s
when it wasn't full of "breaker breaker". Though the three 12v car
batteries used to power the 26v line on G's minuteman missle computer
in the early '70s was pretty crufty. Sending 4800 baud data through a
repeater while a principle engineer from RCA was telling us it couldn't
be done. It can be handy not knowing you can't. ;) Sometimes it was as
silly as putting a speaker to the link lamp of a PDP-8 front pannel and
coding music. By the early '80s hacking was going to disrepute as the
tech wars style came in. Early hacking was serious doing it on zer0
budget, the technically difficult with bailing wire or the subtle
application of brute force. Most of all hacking was doing it with minimum
docs and piecing the picture from it's smoke signals.
that was hacking as I knew it. the last remnents I see todat is people
talking about getting an old PDP-8 or 10 and using a modern IDE disk so
they can power it up and run it affordably.

I forget who wrote half of this, but here goes:

PGA = Professional Graphics Adapter, as Kip Crosby so rightly pointed
out. When I was at IBM this was called PGC (C = Controller).
FWIW, the PGC was three circuit boards bolted together, the two outer
ones going into adjacent slots of an XT motherboard. It had an 8088 as
graphics coprocessor, and did 640 x 480 x loads of colours.
But back to the original question,

No, it isn't PGA. (Although most of the chips on the cards are likely
to be PGAs, in IBM custom metal cans, as I recall...)
The IBM 5272, the 3270PC display, was a very nice monitor. I don't know
the pixel resolution, but I'd guess at 800 x 400. Unfortunately, AFAIK,
it only did 8 colours.
The 3270PC display card did TEXT MODES ONLY - it was aimed at emulating
the 3279 terminal. You could buy two add-on cards for it that went in
the slots either side in the motherboard.
1. The PS card. This provided emulation of the Programmed Symbols
option on the 3279. Very nice graphics, but only as a terminal, not as
a PC (although presumably you could have written PC drivers for it...)
2. The APA card. This provided support of the All Points Addressable
modes of the CGA. These CGA modes were displayed in the top lefthand
corner of the screen. And the only 8 colours reduced the capability
somewhat as well.
It looked very good, but AFAIK IBM never supported it properly. Pity.
Later IBM released the 5370 series machines. These included the
3270PC/G and the 3270PC/GX. These had full graphics capability, the G
on a monitor the same size as the 5272 (but with I think more colours);
the GX had a graphics coprocessor (5378) in a box the size of a PS/2
model 30 and a 19 inch monitor (5379) with lots of pixels (1280 x 1024 I
think, but could have been only 1024 x 768) and I don't know how many
colours (but might have been 64).
But your description of the 3270PC sounds like you've got only one of PS
and APA, alas.
Hope this helps
Philip.
Well, since we're on this subject... how can I resist once more
mentioning...
Slide Rule Trading Post
http://www.comcen.com.au/~adavie/slide/
On my site you will find a link to JavaSlide on the main menu. That's a
JAVA slide rule I wrote some while back, so you can reminisc even if you
can't find your old faithful. Its quite good, actually.
There's a society called the Oughtred society, with around 400+ members.
Each devoted to their slide rule collection. I know of some people with
700+ units. Me, I have 30, including a 7 foot long Pickett classroom rule.
Cheers
Andrew

there are many models of ps1 computers, that its hard to say. the first
2011/2121/2123 were of proprietary nature, and later ps1 types were just
standard 486 pc types. later models had power management and suspend functions
like laptops do. if its a 2011 or 2121 type make sure the monitor works, since
the cpu gets it power from there.

Thanks to all who responded to my request to form an east coast

stay in touch. Would still like to meet more old computer enthusiasts.

OK, well, about to enter high school, I've got this to say: 13 is for
7th-8th grade, so it's 14 minimum for high school. There are, of course,
exceptions, like in Kansas and Florida they enter school a year older, etc.
Actually, here, in 7th grade, we've got 2 14 and one 15 year old(s). And,
people ARE much smarter, but they didn't learn anything in school, if
they're like me.

The age range for highschool in the US is 13 - 19 (approx). You
usually enter around 13 or 14, and finish four years later (older
but in general, not much wiser). 8-P
