Hello (again!).
I'm very pleased with my VAX 4000/300 thus far, but I'm about to get a
KZQSA card from someone, and I need to move my TQK70 controller over on
the Q-bus so that the KZQSA card can fit into the machine. However,
when I did a test run of this, the card was responding (show dev showed
the card), but it wouldn't find the TK70 tape drive attached to the
TQK70. Is there a jumper I have to set? Or did I screw up in some other
way?
Thanks.
Phil.
Hello, all:
I'm looking for a copy of the docs for the Cromemco Dazzler video
board. If anyone has this, either paper or electronic, please let me know.
Thanks.

I was sent a set of GOOD scans of the ET-3400 mods and have created a PDF
file. It's now on the classic computer documentation DVD that I'm selling,
but also I've asked Howard Harte to post it to his site, so hopefully
everyone will be able to download it from there soon (perhaps by tomorrow
(Thursday, 9/9)).
I'm willing to scan any LOOSE (unbound) manuals and produce high-quality PDF
files, I have a high-end 2400 dpi scanner with an ADF (sheet feeder) that
can do over 200 page per hour (of double sided-material) unattended.
Contact me if you think that you might have something not in the collection.
Originals (or copies) can be returned. Bound documents are much, much more
difficult, although I've done more than a few.

Hi Bill
Looking at the parts on the board, it is a multi channel
A/D board. It looks like a Standard Bus but I think there
should only be 50 pins. The TSC 800 is a dual slop A/D
( slow but very good resolution ). The AD667's are analog
somethings by Analog Devices. They might be D/A's or analog
swithces.
It looks like there is a bunch of input amplifiers. This could
be for anything from a simple A/D to a temperature measurement
board.
Anyway, it is definitely and analog interface board.

... wrote a short piece of PDP-8 assembler to do that on the ASR33 for
my nieces. Several of the visitors who have seen my PDPs have asked
for a bit of tape with something punched on it.

I stand corrected :-) I've only seen one of those panels with the
screws before, and it was plain grey.

Say, I found a mighty swell book today at the local ham swap.
Title: The "Compulator" Book - Building Super Calculators & Minicomputer
Hardware with Calculator Chips (How to mate the COMPuter with the
calcULATOR) by R. P. Haviland. Several copies are available on ABE,
Alibris, etc.
NeAt-O!

I think he has the mad hatter syndrome.

Hatters really did go mad. The chemicals used in hat-making included
mercurous nitrate, used in curing felt. Prolonged exposure to the
mercury vapors caused mercury poisoning. Victims developed severe and
uncontrollable muscular tremors and twitching limbs, called "hatter's
shakes"; other symptoms included distorted vision and confused speech.
Advanced cases developed hallucinations and other psychotic symptoms.
The popular top hat of the time were made from beaver fur, but cheaper
ones used furs such as rabbit instead. A complicated set of processes
was needed to turn the fur into a finished hat. With the cheaper sorts
of fur, one step was to brush a solution of mercurous nitrate on to the
fur to roughen the fibres and make them mat more easily, a process
called carroting because it made the fur turn orange. Beaver fur had
natural serrated edges that made this unnecessary, one reason why it was
preferred, but the cost and scarcity of beaver meant that other furs had
to be used.
Whatever the source of the fur, the fibres were then shaved off the skin
and turned into felt; this was later immersed in a boiling acid solution
to thicken and harden it. The acid treatment decomposed the mercurous
nitrate to elemental mercury. Finishing processes included steaming the
hat to shape and ironing it. In all these steps, hatters working in
poorly ventilated workshops would breathe in mercury vapor.

Haven't we all heard about putting on your thinking hat to solve a
problem. Aren't computers just big problem solvers, so by induction a
thinking hat is just a computer.
Personally I hope my wife thinks I'm just "eccentric", not mad. I tell
her it's better that I collect computers instead of wild women, drugs,
gambling, cars, guns, horses, and speeding tickets.

Hi
Now be nice Dave. You know you might need one of those boards
some day. Joe is a great resources.
