Bawls is good, but at my local store, I've run into a variant I like
more - "Antarctica" Guarana soda from Brazil. It's stocked in the
International aisles at the grocery closest to my own house (a Giant
Eagle) and the store closest to a friend's house in Cleveland - so
it's not just us.
It tastes a bit like Bawls (vs tasting like a cola or lemon/lime
drink), but I think it's smoother and less sour.
It's around $3.something for a 2L, so not particularly inexpensive,
but a nice treat.

I have yet to throw it into the rotation for a serious hacking
session, but with a day job sucking up evening hours, too, it's been a
while since I've been able to get my head into that mode for extended
periods of time. Summer is looking good (since I am consulting in the
educational world right now).

I just came across your question about CMC.
My personal knowledge is that it was a competitor of my company in 1968 when it came out with a minicomputer-based system with multiple keyboards to replace IBM keypunch machines. Two of its competitors were Inforex and Honeywell. Another competitor at the time was Viatron but that company didn't last long.

Also,? in October of 2009, Autodesk lost its suit against a man who bought a copy of AutoCAD at a garage sale and then tried to sell it on eBay:

Undoubtedly tape is cheaper (not just per byte but also per drive)
but it's not random access.
Clever things were done with tapes, usually in batch mode. The RAMAC
made it possible to think that multiple files (not in the computer
sense but in the business sense) could be updated simultaneously in
real-time.
It is a fallacy to confuse the cost of a storage unit with the value that
The data on it provides. Clearly as the cost of storage has dropped new
applications that previously weren't economically feasible open up.
e.g. When I got started in digital music in the 80's, the most technically
advanced mixing systems began using hard drives instead of tape for digital music storage and manipulation.

I've wondered this for a long time and maybe someone here can shed some light.
Back in 1975-76 I was using the PDP-11 and Oregon Museum of Science
and Industry (OMSI) and they had a thing called "OMSI RT" on their
system. It was an RT-11 run time system (RTS) under RSTS. They were
selling V1A for $2350 a copy (I still have a copy of the on-line help
file giving the information).
The product ran the Fortran compiler, MACRO, Pascal, etc., as the
later RT-11 environment from DEC did. OMSI RT claimed compatibility
with RT-11 V2 and also required a DEC binary license for both RSTS
(V5B or later) and RT (V2)
My question is: did DEC buy this from OMSI to (improve?) and include
in RSTS or was the DEC RT-11 environment created some other way
(either developed in-house or purchased from someone else)? Does
anyone know the origins of the RT-11 emulation under RSTS?
Thanks,
John
I have a VAXstation 3100 model 38 I bought on eBay for the princely
sum of ?0.99. Sadly it came without disks and I have no wide-SCSI
disks of <1GB.
But I want to get it working & looking at the old dead kit pile.
As far as I know you can't boot a traditional VAX from a disk of
<1GB... but could I put the core of VMS on a small slow narrow SCSI
disk, like an
80MB or something, and put most of it on the only Wide SCSI disk I
have, a 10GB...?
I was considering either attaching an external SCSI2 disk of 80-120GB,
or possibly trying to fit one internally if I can find an appropriate
convertor. I have a fast/wide 8GB or 10GB disk I could use for main
storage, but I don't think I can boot from it... Can I?
My VMS knowledge is /very/ rusty & I was only ever a sysadmin, not a
developer. I've never brought up a bare system or anything.
Also, I have several external SCSI CD-ROMs, including 2 Apple units. I
seem to recall that VAXen want a weird block size, same as Sun kit...
is that correct? How would one tell if a certain drive could do this
or not? Is it a DIP switch setting or just a SCSI bus command?

Hi. First time poster.
I have a bad flyback transformer on a video board that I've been unable to locate. I've also been unable to find any information about this transformer, or the board that it's on. I have lots of information about what the board is inside of, but nothing on the board itself.
It's for a green monochrome Plato Display Terminal, called an AST-1 Student Terminal; even the original designer of the equipment, Jack Stifle at the University of Illinois, does not have any information any more on the video driver board itself. note: The AST-1 Student terminal was supposed to be a lightweight inexpensive replacement for the original Plato IV and Plato V terminals, and was manufactured by the University of Illinois
I've been able to find many defails from University of Illinois archives, including all schematics except for the video driver board.
The transformer is marked as :
VT-521, EIA-528-8521, type sb-1, E36324
I assume EIA 528 means Electronic Industry Association manufacturer 528, with the product (or factory ID) and that's an internal number. The only "cross-reference" is to a SUN microsystems display, but I have ordered that flyback and have found it to be the wrong one...
Here are the links to the photos that I've taken of the board:
http://customer.telswitch.com/plato/ast001.JPGhttp://customer.telswitch.com/plato/ast002.JPG
The first photo is of the "markings" that the manufacturer must have put on, the second photo is of the actual board itself.
The tube that it uses is a Clinton CE745w12h31vrz (which is a standard 745-style tube).
Thoughts?
Thanks!
Aaron
