I could swear I used a 8/I running TSS/8 in '70. Might have been '71. But
might wrong about that.
Anyone have any idea when the first 8/I's got shipped?
(this one had 4 8/L's strapped to it with those nifty green storage
scopes and a funky joystick. we had a lot of fun playing a 'snowball'
game written in a focal varient called COLPAC)

Got all the websites moved. If any of you have trouble with your website on
the classiccmp server please email me directly.
Now I'm working on the last bit... going through the archives and rebuilding
them. A bit more of a pain than I'd normally think, because the mailman
archive rebuild program doesn't handle large files which of course the mbox
files are. So I'm having to break them up by date ranges and import
individually. There doesn't seem to be much in the way of programs to
manipulate and break up mbox files, so I'm writing ditty's to do it.
Once I'm done, the archives should be back up, and searchable with HtDig!!!

Well I seem to be heading towards a usable computer. Sat down with
the manual and re-learned nspeed. First task was to write a script
to create links in the working directory to all the utilities on
DP0. Used the BUILD command (builds 'command tail file lists' in
unixese), and wrote an iterative macro to hash it up.
(There's no "path" to find executables (.SV); it must be in the
current directory or directory specified. Directories in RDOS
aren't heirarchical like they are in unix-derived paradigms;
they're like little partitions, you more or less "mount" them with
the DIR command (mounts the directory and makes it default
directory) or INIT them ("mounts" them so you can copy to them,
for instance.) You specify how many directories you can have
mounted at the same time at SYSGEN time.)
Build makes:
ASM.SV,MAC.SV,FDUMP.SV,FOO.SV,BAR.SV, [and so on]
I needed:
LINK ASM.SV DP0:ASM.SV
LINK MAC.SV DP0:MAC.SV
...
The nspeed command is:
32<1BTABSAJ#C
$ $BS0ILINK ^BA DP0:^BA
$-1LT1L>
Here's one of those maddening things that I'll figure out someday,
and has some dubious reason. The command:
S
$-1D
(Search for a CR)
S
$
(Delete 1 char before pointer)
-1D
Works fine maually. It doesn't work when iteration < and > is used!
That's why I change all occurrences of CR to space in buffer A:
#C
$ $
That works.
^BA
means 'insert the contents of buffer A'
-1LT1L
minus one line; type out line; plus one line, so it
prints the results of edits as it goes.
The leading 32< ... >
Means 'iterate 32 times' because I didn't feel like coming
up with a test for 'end of buffer'. Eh.
Now to write a HELLO WORLD program!

I understand all that but AC power is cheap and so is a fan to dissapate
the excess heat. It's surprising to see a company spent money for features
like this unless there is a very real requirement for them. Even HP doesn't
go to this length with their power supplies.

Oops. I guess it was late and I was tired. I had it setting right in
front of me and I still got it wrong. I should have said EM-180B. I'd sure
like to find a pod for it but it doesn't look likely. BTW I'm assuming
that the transformers for the various models all put out the same voltage.
Is that true?

Well,
Well born in 1963. I had always been interested in electronics and
such. My first computer experiences were in high school. The school had a
TRS80 Model 1 and
accounts on the university's PDP11/45. I had bought a CoCo 1 with
4K! This was in my senior year. I go to the same university. It was
Western Kentucky University (WKU). They still used the PDP11/45 with
RSTE. Additionally, they had access to UK's IBM 360 via a smaller PDP11
with a card reader.
So I got started with card readers and terninals. We ran a pirate exchange
with the microcomputer lab etc. Fun times. I ended up buying the
PDP11/45. Unfortunately a unplnanned move ocurred and I could not find
anyone to take it. So sadly it went to the scrappers. This was before the
Internet. I did keep the console panel.

Now this *might* lead to something interesting.... A few thoughts (in no
particular order)
1) Given the nature of the list, compatability with a _reasonable_ selection
of classic computing enviroments needs to be maintained. This should not
preclude the usage of _newer_ technologies where appropriate.
2) "Conversations" should be easy to follow, with minimal requirements on
the behaviour of the user. For example if there are 100 consecutive messages
on a topic (each one in direct response to the immediate previous one), and
someone replies to message #68, then it sould be easily identifable as such.
3) Bandwidth (client and host) as well as storage requirements need to be
considered.
4) Digest, "Immediate Message" and On-Line Access would all be useful user
interfaces.
5) Searchability [by members and services such as Google] is important if
this is to be used as a reference site.
6) Organization (above the distinction between ccTalk and ccTech) would be
beneficial. Being able to filter messages for a specific computer vendor or
other simiular trait would be helpful.
7) Maintenance/Management issues should be kept minimal since there is no
paid sponsorship for the list [to the best of my knowledge].
8) Elimination of redundant information (i.e. duplicated from post to post
to post) while still retaining context.
That is just a start from my "wish list" view of communications. There are
many issues with making any changes to the method of communication that
would need to be addressed, and members feelings would be among the top.

Which reminds me of how my 80s modem-only line was listed in the
phone book: as "Barn". (I was in the city at the time.) The phone
company wouldn't let me call it "modem". I recall they had a list
of approved descriptions for a line, and "modem" wasn't on it.
So I picked "barn" instead.

I am a young 'un born in 1986. I have always been interested in
computers right from playing my dads PC1640 and Commodore 64 right the
way up to (trying to) build a SPARC based POV-Ray cluster.
I am a UNIX nerd at heart and hate anything with a Micro$oft logo on
it. I have volunteered at the Bletchley Park computer museum since June
2003 and I have loved every minute of it and every week I learn
something new :).

...yeah, and?
Anyone born 1966-01-01 through 1966-02-25 (and part/all of 02-26 and
02-27, depending on timezone) is now born 1966 and age 39.

Back when I was a kid and couldn't afford a real computer, sometimes I
would call the dialup number to the timesharing system (1) and whistle
into it. If you whistled the right way, you could get the other end
warbling and it wouldn't hang up until you ran out of breath from
whistling.
(1) we didn't have any _real_ computers at school, either, just several
ASR33's, a CRT Terminal, a Silent 700, and 'acoustic couplers' to
connect through.
