You can send them to mine if you like, I don't have one, and I'd love
geniune Big Blue RISC machine of my very own..... Do they come with an
O/S?

Alan Kay is also still around and quite active in the Squeak community,
Squeak being a portable revival of Smalltalk. He's now at Disney, believe it
or not.
Which leads to the question... anyone on this list have any Xerox Stars
(running Smalltalk, of course)?

RTs were pretty bad. They were s l o o o o w w w...
And they had the most bastardized version of anything
daring to claim any kinship to UNIX that you can imagine.
The manuals were terrible. I suspect that if you were from
an IBM mainframe world, being forced at gunpoint to consider
PCs and UNIX and such, they were heaven-sent. But to
those of us already working with workstations and micros,
they were the Red Menace that Senator McCarthy warned the
world about - they just happened to be Blue.

Quick vignettes...
1) I contracted for IBM here in Austin for a while. There
was an RT on the austin.ibm.com network named "doorstop".
AFAIK, about all it was being used for was to answer the
pings for "doorstop".
2) At PSW, Frank King (the IBM upper manager who more or
less built the IBM workstation division) had just been
installed as president when we took him on a tour of the
premises. As we escorted him into the secure lab, his
eyes lit up as he saw an RT.
``An RT! Wonderful! What do you use this for?''
Tom Stewart pushed it in front of the door to hold it open.
``A doorstop? What else?''
3) During the time I was at IBM (14 months) I saw rooms and
rooms full of RTs. I kinda have to laugh, thinking about
what they were paying for space. One of the graphics labs
had about 30 linear feet of wall space, 10 feet high, just
stacked with the processor boxes, because they were running
out of other places to put them. I never figured out what
they were doing with them - whether they couldn't give them
away, or were afraid to, or what.
If I had one, I would probably protect it. If I had two, I
would protect one. For the other, I would have an auction.
The high bidder would get to step out back onto the rifle range
(why have 5 acre sin Texas without a rifle range?), and put a
7.62mm bullet into the RT's evil, beating heart.
And in Austin, there would be *lots* of bidders. I might not
make $6,818.00, but I'd make enough to pay my ISDN bill for
a while...

Nah, I'm sure there are 3rd world countries that would take them.
But after they had them a while, they'd be even more pissed at
the US than they are now... 8^/

And the computer was ....
You guessed it the COSMAC Elf! And IIRC, the article was "Build a COSMAC
Elf for Less than $100"
Anyone got the issue date?

Working on a work-around at the moment wherein we need to store 5 digit
numbers, but the database (deployed at nearly 400 stores around the western
US) has only 2 bytes for this field. Unfortunately, COBOL only allows
values up to 9999 to be stored in a two byte field, even though 2 bytes can
(in theory) hold numbers from 0 to 65535 (or -32766 to 32767 or so).
So we need 4 bytes for COBOL to be able to deal with the new data. But, to
roll out a database change like that to the stores would take 5-6 months
(can't just muck around with live production systems, you know, and you
can't do anything while the stores are open (i.e., taking in $$$).)
Interestingly, the numbers we need to deal with are all less than 32000, so
they will fit in 2 bytes. So the work-around will be to store the data as
two character bytes and convert that within the program into a temporary 4
byte field. So what happens when the numbers get bigger than 32K? Well,
I'm sure the system will have been replaced by then... 8^)
(Actually, it will have; the new, replacement system was supposed to have
been finished by now. We're just patching the old system until it's done.)

In the late 1980's, I worked with a company that wrote software for leasing
companies. Companies that leased big computers and heavy equipment. In
addition to getting to know amortization tables intimately (I used to know
the formula to compute payments/periods/rates/etc. by heart!) I got to know
the y2k bug pretty well -- most of the leases were 10 year leases. We had
a y2k version out by '90 or so.

You don't have a monopoly on that. We seem to have the same problem.
It's probably due to the fact that mostly nincompoops run for office.

Hey, check this out! I was just watching Jeopardy and the first
contestant said he was a collector of antique computers! Alex asked him
what his oldest computer was and he said it was the first one he ever
owned, which was a kit he bought thru Popular Science for $99. His name
was Dennis. Is there a Dennis lurking on this list?? :)

Seth, Doug,
Thanks, you're right, I'm confused. Looks like I'll track down NetBSD for my
DECstation, and look into buying a VAXstation 3100 at some point.
Thanks again,
- Joe
