As far as I can remember, every straight 8 I've seen in the wild and
almost every picture I've seen has the dark plexiglass panel with the
paddle switches similar to those on the 11/20. However, I have a copy
of the user's manual dated 12/64, and the picture of the machine on
Page viii has what appears to be a simple brushed aluminum panel with
little light bulb covers sticking through it and the switch register
switches are all ordinary mini toggle switches.
So my question is were there any ever shipped with that style of front
panel, or was that picture of a prototype that was revised before any
shipped?

I snagged this record off eBay because I knew it had to at least be
interesting... thought you all might get a kick out of it:
http://yahozna.dyndns.org/scratch/softwaresounds/
(mp3 and raw wav available)
It's entitled:'Software Sounds - "Music for the Computer Professional"'
and is apparently the creation of a man named Laz Bouros (who apparently
never made it as a rock star but is today an Executive Consultant, if
the Internet is leading me true). There's no date anywhere on it, but
it has to be from the early-mid 80s.
It came with a small pamphlet describing the both the record and the
record label, which I will transcribe for you:
------
The Company:
Software Sounds is an independent Canadian record company dedicated to
developing a new market in the record industry through the use of an
innovative musical product.
The Market:
The millions of computer professionals who operate, program, design, and
manage computer systems throughout Canada and the U.S. provide a dynamic
yet untapped market for the music industry.
The Products:
"Computer Songs", in a soft rock format, with lyrics that capture the
human struggle as well as the lighter side of the computer world, are
the new musical products.
The Writer:
Laz Bouros, a computer consultant and composer, has spent many years
working in the computer environment and has written many songs on a
variety of themes.
-------
Alas, music for "the millions of computer professionals" never caught
on, perhaps it couldn't compete with Devo andKraftwerk?

I have a fully functional 2/120 and disk tower, with a 2/50 client.
I would be happy to help with any issues that your system might have.

I have to agree with the above.

On the other hand, I regard protective ground as something that seemed like
a good idea at the time but what protection it would provide and how did not
seem to be adequately thought out until much later versions of the standard,
if at all.
When making up an serial cable, I usually leave it out, not out of laziness
but because I think I'm probably as well or better off without it.
(at least that's my excuse and I'm sticking to it!)

Peter Coghlan.

Well, if you check out some of the other classic computer lists I think
you'll find that the above environment is still very much alive and you'll
find some of those 'silent' folks over there instead, as I'm sure some folks
on here who also belong to those other lists can confirm; the day rarely
goes by when Chuck doesn't help someone with advice, an uploaded file or
two, even on occasion a small custom program over on Erik's Vintage Computer
List, and there are many, many other people helping each other out, trading
parts, building new add-ons, sharing experiences etc., there and on other
lists like the Cromemco list, Club100 (R-S), CBM-Hackers, etc. etc.
Sure there are more 'collectors' these days who are interested in $$s, but I
think that's really almost a separate issue altogether and I don't see much
of that on CCtalk anyway.
I'd say that it's not so much the hobby that's changed, but the mood and
character of this list, or perhaps it's only remained the same while others
(especially the VCF) have sprung up where newcomers are warmly welcomed,
birthday greetings are exchanged, 'PeeCees' and Microsoft products and users
are not disparaged or insulted, nobody quibbles over top vs. bottom-posting,
name-calling is discouraged, and for the most part people talk about classic
computer issues. As I said, you'll find some of the folks who are now
'silent' here hanging out over there instead, not to mention those folks who
are on several lists in addition to this one and generally much more active
on the other lists; even Gene tends to be much nicer on the VCF ;-)...
I have talked to several people who thought it would be useful to join
CCtalk, but after reading through a few days' worth of traffic decided it
would be a waste of time...
That's really my point when I climb up on my soapbox...

Subject: Decwriter power supply transistors R3004
Hi all,
The LA-120 Decwriter that I got off Craigslist a couple of weeks ago has
a dead H7150 power supply. Transistors Q1 and Q2 are open and shorted,
respectively, and fusible resistor R4 is open. I'd guess that failure of
Q2 led to the other two parts going.
Q1 and Q2 are high voltage NPN power transistors in TO-3 cans, labeled
__
81 [ti logo] 41 (or maybe 4I but I'm guessing for a date
code, 41)
R3004
BRITAIN
DEC part number appears to be 15-12782-00. The printset identifies them
as "NPN 100W S1325 15". I can't find any substitution info online. There
is a NOS pair for sale on eBay. So that's one option. Does anyone know
what the modern equivalent(s) are? And what if you do, where did you
find the reference?
Thanks,
Brian
This is evidently the connector on the Kaypro keyboard:
http://www.digikey.com/product-detail/en/TM1R-616P44-35S-150M/H11390-ND/113…
Well, close to it, anyway. The original seems to be a Berg 616p
And yes, it's erroneous to call it an RJ9, but it's easier to find in
the store if you go that route.
Before I go plunk down $7.10/connector for 5 connectors (mouser has a
bit cheaper price, but their pic is wrong), anyone have a source that's
not so steep ($36.00)?

30 AWG is for modern wire-wrap. 24 AWG is for older systems and controllers
like the Classic PDP-8, PDP-9, TC01, TC02, TC58, and TC59.
