I used one of these in honors CS302 Intro to Computer Programming (in Pascal) Fall 1984 at UW-Madison. We were the last bunch to do so.

The Terak 8510/a is a desktop workstation with an LSI-11 compatible processor, a graphical frame buffer, and a text mode with downloadable fonts, used in the late 1970s and early 1980s in some U.S. universities. Despite the lack of a MMU, it was capable of running a stripped version of UNIX version 6. It was the first machine for which the UCSD p-System was developed.
The Terak 8510/a was the first graphics desktop computer system. In conjunction with the UCSD p-System, it provided immediate graphic feedback from simple programs encouraging students to learn. Three entrepreneurs created the company in 1975: Brian Benzar, William Mayberry and Dennis Kodimer. The products were manufactured in Scottsdale, Arizona from 1976 thru 1984. Sales reached M and Terak was publicly traded in 1983-84. Besides the original frame-buffer-centric 8510/a, other products were developed: color graphics and a Unix workstation. Eventually Terak succumbed to two forces: the sales juggernaughts of Sun, IBM and Apple plus venture capitalists with little expertise in the computer industry. A Terak computer was on display at the Boston Museum of Science and also the Jefferson Computer Museum.
What is a Terak?
It is an early personal computer made by the Terak Corporation of Scottsdale, Arizona. It was sold from about 1979 until 1985.
One of the first models was the Terak 8510/a shown above. It was based on the popular PDP-11/03 processor, a 16-bit CPU. The Terak 8510 could have as much as 128K of RAM with the PDP-11/23 option. For storage, it has big eight-inch floppy drives that go klunk-klunk, in IBM 3740 format, holding roughly 256K, 512K or 1 meg each. Hard disks of five to forty megs were available. The Terak featured both RS-232 and 20 milliamp current loop serial connections, so you could connect to the printers and teletypes of the time. The keyboard included a numeric keypad and arrow keys arranged in a vertical column.
The Terak was advertised as a "Graphic Computer System." It featured a monochrome 320 x 240 square-dot display and relatively advanced video features such as a purely bitmapped display, allowing a customizable character set, the mixing text and graphics on the same screen, and raster operations like continuous smooth panning and scrolling. The system included a twelve-inch composite video monitor. It even had programmable sound and a two-inch speaker. The main system box was robust metal, weighing about forty pounds.
Available operating systems included the UCSD P-System and RT-11/85 version 4.0. Languages included Pascal, FORTRAN IV, APL and BASIC. Someone even ported an early version of Unix to the Terak.
In November 1981, an 8510/a with 56K of RAM and one floppy drive was ,935. And extra floppy drive was ,570. You could even upgrade to color graphics at 640 x 480 by eight colors for ,550. A ten meg hard drive was ,985.
The Terak was popular for teaching Pascal to college kids. As such, all the oldsters who were in college then and used this computer have a great affection for it, meaning they can no longer remember how slow they were. Its flexibility in character sets led to its use as a text editor for Russian and Hebrew.

I have several Terak 8510/a and hundreds of floppies. I bought the first one in 1990 for about at a University of Wisconsin–Madison Surplus equipment sale. At one time, the UW had about a dozen Teraks in the computer science and math departments, including about eight that were available to students in entry-level programming classes.
I have old Terak sales literature, and several years of issues of TUGBOAT, the Terak user group newsletter. Many of these disks and all of the ephemera were donated by gracious former Terak users and owners. TUGBOAT had a collection of public domain software. Sadly, I only have a few of these disks.
Two of the founders of Terak have visited this page. The first was Bill Mayberry, still living in Scottsdale. I hope to speak with him to learn more about the history of the company. Dennis Kodimer followed. The third founding member of Terak is Brian Benzar.
The Museum grows
If you know of someone who still has a Terak hardware or software, please have them contact me. I will give their material a good home, and will gladly pay the shipping charges, which can be considerable given the weight of the Terak
Teraks are becoming more and more rare for obvious reasons: most people have no use for computers with the horsepower of the original IBM AT, especially one that isn’t an IBM AT.
In July 1997, I got a second Terak from the UW Surplus. I’m not sure it works. The main floppy is single-density, not double.
I also received a donation of a Terak 10 megabyte hard disk drive. I’ve found another nearby person who might be willing to sell his Terak. Someone else donated a case-less Terak, covered in cat hair, but perhaps good for spare parts.
In June 1998, UW Surplus comes through with another Terak 8510/a for , and another visitor donates an 8510/a in exchange for my effort in recovering approximately 100 floppies of vital data.

I finally got a bigger bookcase for my office. I still have books on the floor and double stacked on the bottom row (and even books behind them)… time to start giving them away.

Novell Marketing Video for Linux playing on the popular Mac vs PC videos. What is Linux? See: en.wikipedia.org Some points for Linux off the top of my head: – Free (as in speech). I have the freedom to tweak the system as I wish. – DRM Free – Superior method of software updates, installation – Solid stability (servers I run have been up for 1+yrs, my desktop 1+ month) – Can scale down to very old/obscure hardware (I have a Linux file server running an old 266, 24MB ram – Virtually Spyware/Virus free – Variety of system tools not available in Windows. Extensive programming interface. – Very cool eye-candy ahead of other Operating systems. Youtube search “compiz”, see the upcoming KDE, see the current version of Gnome. – I know exactly what my computer is doing. Can’t say the same thing with Windows, OS X – Although I agree gaming is lacking, I personally don’t game on PC but what I do see is the amazing benefit of being able to have access to the thousands of OSS packages out there. – Luxury of using technology backed up by contributions and usage by companies such as IBM, HP, Sun, Google, many governments, military orgs, NASA, universities, super computer research. Outside the desktop Windows presence is not the greatest. – Constant updates to all my software. You can choose to run cutting edge or run stable. – Ability to decide what to install and what not to (can’t say the same thing about XP) – Freedom of not depending on one single vendor. I know my needs will not be …
*MOST RECENT UPDATE 6/12/10* This tutorial, if you can’t tell, is severely outdated. I will save you the frustration of trying to follow it by telling you to find another tutorial. There was annotations on it awhile ago, but youtube deleted them after attempting advertising… Sorry. *ANOTHER UPDATE–PLEASE READ* Many of you are having version compatibility problems. If this is the case, try downloading GIMP v. 2.4.5! Also, Many of you are experiencing slow motion images. Here is the fix: On the basename it goes “frame_[######] (40ms)” You are suppose to ONLY change the ‘frame’ part of the basename not the whole thing. The numbers are the frame number that will be plugged in and the (40ms) is the frame rate. That’s what you change if you want to change the speed. If you want to keep the default video speed don’t change that number. Only rename the ‘frame’ part. Use this link to download GIMP: sourceforge.net The GIMP animation package (GAP) can be found here: registry.gimp.org It is an installer for WINDOWS operating systems. There is none I know of for MAC or UNIX based systems. Mediacoder: mediacoder.sourceforge.net [Please Read] I added annotations to make the video clearer. Hope this helps!

www.apple.com You may wonder : why would Mac have so little virus ? and guess this is probably due to smaller market share than Windows…. The reason is actually the underlying UNIX FreeBSD system that MacOSX uses as a base and that simply makes it impossible to have virus on Mac.
