No, I suppose there isn't, assuming one knows what the term means at
all, because it's common in modern processors.

I don't know much about the inner workings of Alphas, so I didn't
mention it. Nor do I know all that much about the inner workings of
R4K prior to the R4600, except that I know an R4600 will outstrip an
R4400 at the same clock speed (modulo cache differences) and an R4400
will outdo an R4000 by a fair bit. In fact, the earliest R4000 chips
were embarrassingly slow. I don't think R3000 or R4000 had speculative
execution, but I'm not absolutely sure.

I'm sure you're right. I've almost deliberately avoided knowing too
much about Intel chips post-8085, except to find out what MMX really
does, and discovering along the way that Intel do seem to have changed
their minds a few times.

I have them as well. I should have a grandfather tape or two around also.
Jay, have you ever seen any documentation of what the added instructions do?
I turned up some docs from Sam on RTE4, and at that time they were MMU related
and may have included queue and some of the OS scheduler.
I found a post online that you once had a Tektronix 7854 Waveform Calculator
(http://www.classiccmp.org/pipermail/cctech/2003-January/007249.html) I
have a mainframe that needs one. do you still have it?

I thought the R4600 was, though maybe it was early 1994, but actually I
wasn't claiming any particular date -- just that they do speculative
execution.

I meant the Pentium family. Yes, I knew the Pentium Pro was the first
-- and it didn't work all that well so Intel changed the branch
prediction algorithm for the Pentium II.

We received a letter (on real paper, envelope and all) here at Virginia
Tech yesterday from an elderly couple who need some help converting from
old 5.25" floppies to somewhat less old 3.5" floppies. The letter was
address to the "Computer Department" but for some strange reason it
ended up in my cube. Other than plugging a few cables into the new G-5
Cluster, I have no experience at all with Apple stuff. If any one on
the list can help these folks out, I'm sure they would appreciate it.
Here is the text of the letter:
-----------------------------------cut------------------------------------
213 Heady Avenue
Louisville, Ky 40207
10 November 2003
To the Computer Department
Virginia Polytechnic Institute
Blacksburg, VA
Dear Computer Genius(es),
Can you help us? This is a serious request.
We have an old Apple II c or gs word processor (old = 1985).(We are also
old, 65 & 70.)
We have important data on about 30 5.25" full floppy disks from it,
which we are trying to "CONVERT" to the newer 3.5 disks. It would take
years to retype it all.
We need all kinds of "exact" help - people have been "trying" to help us
and we can't get anywhere, i.e., we have an antique and expensive Apple
II 3.5 disk drive bought from a reseller. Now we are having trouble
finding the old single sided 800 KB 3.5 disks we believe it takes. IF
we find those disks, we need to know the process for transferring the
data.
IF THERE IS ANYONE IN THE COMPUTER DEPARTMENT WHO REMEMBERS HOW TO DO
THIS ANCIENT TECHNOLOGY - and where we can by the SS 800 KB disks - and
could they please help us with simple step instructions?
Our e-mail can be used to send instructions (simple, please)
dkelly(a)worldnet.att.net
We would be very gratefully if anyone can help. Thanks for reading.
Sincerely,
(s) Dave and Wanda Kelly
Dave and Wanda Kelly
---------------------------------cut-------------------------------------
So, it looks like they need a source of disks and some instructions on
how to copy the files.
If any one can help them out please send them email direct to the
address in the letter.
