Gary:
You have posted to a discussion group. Your friend
meant to give you my personal e-mail address
(weese(a)mind.net), I think.
(I believe you are writing to me, as I haven't seen
LNW stuff mentioned in the last month by anybody else
on this group.)
I'll write this both to the group, to clarify, & to
you personally.

A IIcx for C$25 isn't that bad, assuming it has a decent size hard drive
(80mb+) and some ram (4mb+). If it comes with a keyboard and mouse as well,
and/or video card, you're doing pretty good. I would definitely pick one up
at that price for Rachel's classroom. (The IIci is a little nicer, but a
IIcx is very acceptable.)
Note, if anyone (especially in the SF bay area) comes across mac stuff cheap
that they're not interested in (especially monitors!) I'm always looking to
get more computers into her classroom. (In case I haven't mentioned her
before, my girlfriend (Rachel) is a 1st grade teacher in Daly City. We've
put 10 or 11 macs in her school (8 in her class) so far, mostly based on my
scrounging (or buying) parts and refurbing them.)

I know that this is a little off-topic, but here it goes. I'm reading
the book "The Soul of a New Machine", a book about the development of DG's
Eclipse minicomputers (great book, BTW). In there, they talk about a
"microcoder," one who is responsible for developing the microcode for the
processor.
Inutitively I know what microcode is. I think of it as hard-coded ROM
for the instruction fetch unit of the microprocessor. Since I haven't been
formally schooled in computer science or microprocessor design, I'd like to
understand (in 500 words or less <g>) how microcode works, i.e., how is it
implemented and how does the microprocessor access it.
I know that this is probably a topic that is worthy of volumes of paper,
but the Reader's Digest version will do! Thanks.

This should make for some interesting reading...
I just says "PDP-11/40 system engineering drawings".
The dates on the schematics inside say 09/22/72.
Oh! This also includes the terminal?
I guess this IS the "system" schematic...
I was told that when you bought a PDP-10 that DEC included the operator's
chair... and that the schematics for it came in the printset.
I wonder what the part number would be for a PDP-10 console chair...
Is this bull? Did they REALLY include the chair?

I'm 30 now, started playing with a Bell+howell apple][ in junior high
school. Bought my first computer, a Timex Sinclair 1500 in 82, my freshman
year in H.S. Everyone thought I was a big weenie and I was never socially
accepted. in 85 I finally got an XT, I wanted an Apple][ but they were
going by the wayside so I decided to get the XT scrictly based on software
availability. I was a manager at Pizza Hut, things were looking grim for
my future, I couldn't afford to go to college and was married. Then I got
sick of all this and joined the Coast Guard, went to MST School in Virginia
for the Coast Guard, 30% of MST's are system managers of some sort. I
thought I might get lucky, I did, I scored a 99% on the computer section of
the course and was made System Administrator of the 4th floor of Coast
Guard Headquarters in Washington DC. I then got out of after my tour, I
now collect older systems as a hobby, im way past 40 systems now, I have no
idea how many I have, my new wife , hehe, another long story, tolerates it,
and Im a network engineer for the Dept of Labor. I owe all this to Sir
Clive Sinclair and my mom for encouraging my interest. I make about 43k a
year, own my own home, not too bad for 30 and not a day in college.
Good luck, and don't give up.

Does anyone remember seeing adds in popular electronics back during the 1970's
about the NRI computer .
A few examples were on page 37 of the 3\77 issue , .page 15 , 11\76 page 11 ,
2\76 .

For "fantastic" substitute "legendary." During my years as a support tech
(roughly 1986 to 1994) it was an article of faith in my firm that a "bad
disk" was a failed controller about two times out of three. This could be
difficult to explain to end-users, who generally knew what a hard disk was,
but rarely what a controller was, or even that they owned one.
It was also entertaining telling an end-user that, once they had a new
controller, they'd have to low-level the

I've got some TK-50 drives that I want to use a couple of in my MicroVAX
II, they are all filthy, with big dustbunnies crawling out of them. I've
picked up some of the proper foam swabs for cleaning tape drives, and a
bottle of "Radio Shack Professional Tape Head Cleaner Fluid".
I took the worst one tonite and striped it down, gave it a good cleaning,
blew it out good, got it nice and spick and span. I've got it put back
together now, and it _looks_ great.
My question is, was this a good idea? I started thinking about this when I
went and put the thing that looks like it has two magnets back in from of
the tape drive head. By taking this apart like that have I messed up the
drive alignment or anything? Are there any particular gottcha's that I
need to be aware of. I'm already aware of how the tape leader needs to be
attached and what to do if it gets sucked into a drive (had a tech show me
on a DLT4000 drive a few months ago).
Of course my plan is to install it tomorrow night, and give it a try. It's
called I really want to get a good backup of this machine prior to starting
to play with it (I know nothing about VMS, but have the System Manager, and
User's manuals).
