Hmm, it sure looks like it!

Louis,
Welcome aboard.
Joe's and several other collectors are in Orlando. I live in the Ft.
Lauderdale area but will be in Orlando that weekend. Once we get a little
feedback, we'll set a time and place.
Is Saturday September 8th OK for you?

Jumping in late, I know, but when I was at Georgia Tech (mid- to late-80s),
we were taught x86 assembly. There was a real focus on the concept that
"look folks, there's an awful lot going on under the hood that you might
want to be aware of when you write that Pascal (or C, or Lisp, or whatever)
program and the details matter". For that lesson, x86 asm is a pretty good,
if painful, object lesson. Much of GaTech was like that.
Oh, yeah...and we learned Modula-2 from Kim Kings book for undergrad OS.

Ah, one of my favorites, used magnetic core for the memory;
however, it would usually lose a byte or two on either
powering down or back on again...

Hi All,
I have a Zenith H-89 based computer control system which needs few ICs.
Any body know place to buy these?
D765AC
C8208 - CPU?
C8087-1
WD2123-PL - I guess western digital disk controller.
Thanks for any info.

This is fantastic -- thanks for sharing.
Being a musician, this conjures up all sorts of ideas for using computer
sounds to make music. I have a recording studio hung off my main
non-classic box, so I can add this to my List of Unfinished Projects. Some
useable sounds might be:
(printers, of course)
hard drive spinup & chatter
crt charge & discharge
floppy drive stepper motors
ps fans
cpu cooling fans
cd drives (opening, closing, and spinning)
scanner sounds
tape drives
ASR 33s
PAC readers
card readers
So what did I miss (classic or non)?

This might be of interest to somebody here (hopefully)...
Surplus Traders (www.73.com) currently has 35 Nabu computers for $29.00
a pop, plus shipping. Normally they do bulk sales, but they will sell
the Nabu individually. (Search for item CR356.)
I picked one up a while ago, and mine was still 'new', in the box, with
a factory seal. Then again, since this surplus, it might be best to
verify that the units are 'new' if that's important to you.
Unfortunately, I haven't really toyed with the Nabu hardware too much
(yet), and if anyone else has, I'd love to hear about it. Either way,
these machines are certainly an interesting part of computing history.
Here's a small blurb about the Nabu:

Well this is the weekend that I'll try and get the PDP 11/34 running
as well as the AS400's in the garage.
Anyone who will be in the Ottawa area is welcome to come and help.
I'd like to see some signs of life before packing the magnetic media
into the basement for the winter.

Anybody know a source of DEC rack header panels (the maroon/red ones)
with or without logo, or for the black "cover panels"? I've got a
maroon/red pdp11 header panel, and a "blank" maroon/red one, but not
the black panels to cover the rest of the cabinet..
