What about something like an exhaust hood over the 11/70, and a fan?

Hi,
I usually hate organizational issues, but I think us VAX collectors
need at least a semi-formal organizaton. Why?
- Most importantly this could help convince those that either
decomission or scrap VAX hardware to give it away instead.
(Yes, the last wave of decommissioned VAX 6000-600 and
7000/10000 is coming up, plus the tail of older models that
might occasionally still be in use.) Also think of all the
overpriced DEC hardware suppliers who soon have to get rid
of their stocks that no business customer needs anymore.
- Second this would give one point where we could organize trades
and consolidate shipment issues ("VAX trecks")
- It could help us negotiate good truck rental rates. Penske has
perhaps the best rate you can get, but not everyone gets the best
rate (i.e. 10 cents per mile) because that's for business customers
only, normally. But usually with an organization (and a little ad
on the web-site) you can get good deals on vehicle rentals.
And it goes on.
- We could promote semi-public collections like little private museums
that some of us are building.
- Finally it could help in right out fundraising for covering such
expenses as electricity and internet connectivity for cyber-
museums and public use VAXen.
We don't have to start all over but can take something that already
exists. (I'm also not looking to become a chairman of anything,
one of the typical incentives for people suggesting new organizations :-)
For example, I think this can start with a web site. Some of us already
have vax related domain names which we can use, like Isildur's
vaxpower.org. So, a www.vaxpower.org could be it. There's also the
VAX rescue squad, put in my several futile attempts to sign up
I realized that this project seems rather dead. I don't know if this
should be anything tightly connected with DECUS, because DECUS is
(a) too COMPAQ or whatever.com oriented, (b) too VMS oriented, and
(c) seems to have too much overhead (organizational structure,
membership fees, unrelated agenda items). But I could be wrong
about that.
Another question is if this should not be a DEC/VAX only group
but rather a vintage computer stuff group, like Sellam Ismail's
site. May be this could be it. What's important is that this site
would help accomplish above-mentioned goals, and that it would
be a showcase of our VAX collections and simply an address book
of the kind that the VAX rescue squad wanted to be. Something you
can point to when negotiating with a source. A network of friends
you can call up and ask for help in rescuing someting in an
otherwise remote area. Also a set of rules of conduct dealing with
shared hauls, (like what if: you agree to help with a haul from
a friend accross the country and agree on keeping certain things,
but suddenly a PDP-8 shows up in that lot? These are things that
could help maintain friendship and integrity and reduce grief.)
So, what do you think?
regards
-Gunther

I was just about to say, I seem to recall that my old Northstar used them
(although I can't remember if it was an Advantage or a Horizon, it was a
black boxie CPM machine with screen, keyboard and floppy drive all in one
unit).
I also think the Apple II had a hard sector option (had to load a special
disk to activate it... or was that 13 sector... or are they the same
thing?)

Are you talking about a MS Windows box here??? As a PC builder I must say
that if I were into serious gaming I would absolutely buy a game console.
Say you buy 3 pricey, high-quality games for your PC. Chances are one of
them won't like your video card. Or the version of DirectX you're running.
Or the gamepad you're using. Or the motherboard's chipset. Or it'll step
on another game by replacing DLLs. Or it'll change the sound settings so
the other games have problems.
Not my idea of *fun*.
On the other hand I suppose you could consider the "real" game to be
getting more than 3 high-quality games to run on the same Wintel box ;>)

Hi,
after my pretty good VAX treck last weekend (more details coming
up on my project web site at a later time) I finally have SDI disks.
I hooked one up last night and did all the checking as per the
RA9x manual (yes I have one plus many more, will scan those at
some time...) and it seems to be O.K. (even though it was pretty
messed up stored in a barn among lots of birds for many years).
Here is one para about where I am at and then I have some
specific questions for Geoff Roberts or Ragge or anyone who
has had experienced any luck with getting a 6000 up to operation.
I have bootable tape for Ultrix 4.1 and VMS 5.3 both TK50. None
of them work. I seem to have no luck with the TK70 and I have
no way finding out what's wrong. I tried to boot from that RA90
disk, even though I don't know what's on it. It has unit #0, so
I thought it might be a system disk. But that too failed with
some I/O error very early in the process. I also have a TU81+ and
VMS bootable tape on 9-track, maybe that's more reliable? Tonight's
project is to move the TU81+ into the basement and hook it up.
I'm afraid I'll get stuck there too and what then? Network
booting?
Here's some more detail and questions:
The TK50 boot proceeds for quite a while, although it never shows
any message on the console about where it is at before it halts
due to some unspecified error. However, about one or two minutes
into the tape running the system-panel's FAULT light comes on and
at the same time both yellow and green LEDs on the TKB70 board
extinguish. That's for about a second or two. Then the lights
go back to normal and the fault light turned off. Another 30
seconds to a minute tape streaming and the same light-spiel happens
again: fault on, TKB70 LEDs off, and back to normal. Now a shorter
time (like 10 seconds) of tape streaming and again. From now on that
repeats for about 4 or 5 more cycles and finally the system is
halted and console says: system halted due to previous error.
However, no error message is being printed. I have no idea where
I am in the process.
I have tried cleaning the TK70 read/write head of course. I have
tried a different copy of that Ultrix tape. It's always the same.
Is this bliking of fault and shutting off of both TBK70 LEDs
normal for media read errors or does it indicate something more
serious? How can I tell where in the process I am? Is there an
error flag somewhere in memory that I could EXAMINE to find out
what is wrong?
BTW: at first I had my CIBCA cards in and the boot process would
halt earlier: system would say "insufficient memory for CI" and
"10% or more of the memory is bad". Who is checking memory there?
I could not find anything in Ultrix 4.2 sources that would generate
such a message. And why would it anyway, because my system check
tells me that I have 512 MB of memory OK. Or does it speak of
10% of the CIBCA's internal memory?
Is there a boot flag that I could turn on that would cause the
loader etc. to be more verbose?
Has anyone tried booting Ultrix over the network? I am going to
try that but all I have is Ultrix on TK50 (that doesn't work)
and sources without any VAX running to compile them on. Is there
a cross compiler suite? I'd like to compile with the DEBUG
flag set.
Thanks for your suggestions,
-Gunther

Hi,
I have an Epson QX-10 in excellent condition, including the 300 baud modem
and the 8088 sisterboard upgrade, monitor, keyboard, software, technical
manuals, etc., along with a second cpu box for parts. Any thoughts on the
best way to find a collector who might be interested?
Thanks for your help.

I've not followed this from the start so I don't
know how deep into the HSC90 you want to
go, but the steps for upgrading an HSC90 to
an HSC95 may help.
1. Power off.
2. Turn the nylon catches on the card cage cover
1/4 turn each and pull cover up and out.
3. Swap modules to taste.
For removing the rear door:
1. Open door.
2. Release hinge pin by pulling down on release lever.
3. Slide door out and lift up: do not bend bottom pin.
I've never (knowingly) seen an HSC6x or HSC9x so
all I can say is that it sounds pretty easy so I
assume you are doing something other than
swapping modules?
The IPB suggests that the side panels "hang" on
the sides and, once the top is off, will slide upwards
until they are clear of their "hooks". There may be some
obvious screws involved too (it's not immediately clear
whether this is a different cab variant/rev or not).

Gee, I've been doing this all wrong; I offered several boxes of data & related books for free, but had no replies at all - just found a box that I overlooked when I tossed 'em out, so let me try adding a handling charge & offer them for $4.95 ea. & shipping :)
Zilog Microcomputer Components Data Book Feb 1980
Intel Microcomputer Systems Data Book 1976 (SBC's &c)
Intel Component Data Catalog 1980
Intel 8048 Family Applications Handbook Jan 1980 (Apps & Assembler listings)
Intel 8080 Microcomputer Systems User's Manual Sep 1975 (Apps & data sheets)
Rockwell Electronics Devices data catalog 1981 (AIM65, RM65, System65, R68000, PPS-4/1, modems &c
AIM65 4 Manual sets: User, Programming, Chipset & Monitor Listing
The Elementary Apple 1983, Wm. B. Sanders (Datamost) (Beginners's User/Programming)
And some Mostek & Synertek sheets as well; they were mostly into F8's and Z80's; you're probably thinking of MOS Technology for the 6502, and I just happen to have the
MOS Microcomputers Programming Manual
so after you get your $5.00, just send me 4.95 <g>

Subject: A couple old books, 6502 and Mostek
I found a couple books while digging in boxes at TRW.
Beyond Games: Systems Software for your 6502 Personal Computer. Ken Skier
This is a very early book, copyright 1981, covering a series of articles
>from BYTE magazine. Lots of low level nuts and bolts software, a monitor,
assembler, text, printing etc., but with a very basic approach, and over
half the book are reference listings etc. Has a few specifics for each of
Pet, Apple, Atari, and other 6502 computers.
Mostek, MOS Integrated Circuit Guide. Magazine sized, 138 page, blue and
silver book, copyright is 1975, but the only microprocess it mentions is
the F8, and I was expecting 6502. Covers several early memory chips and
some consumer calculator chips, very nice condition.
I am thinking about $5 for either book, but best offer and postage gets it.
