DATAPOINT CORPORATION
Datapoint 2200

In the very late 1960's, 2 professors at Case Western Reserve University in Ohio came up with the idea of a high density integrated circuit which would be programmable. Its purpose would be to a programmable/adaptable physical interface. They took this circuit design to various IC manufacturers and were turned down by all of the existing IC manufacturers. The reason? The chip was too specialized and would never have enough widespread applicability to be financially worth developing.

Having failed to convince any IC manufacturers, but still believing in the concept these 2 professors pressed on and went looking for manufacturers who would have an application for the new chip. They found such a firm in Computer Terminal Corporation (CTC), which made a variety of lower cost computer terminals which were compatible with the various computer companies. CTC was interested in the chip because it presented a way to make one terminal that could be programmed to behave like and handle the protocols of a variety of different computer manufacturers. [This was the days of Snow White (IBM) and the seven dwarfs: Sperry, Burroughs, Honeywell, GE, Control Data Corporation....] CTC agreed to pay two different chip makers to produce the chip. Both chip makers decided to use a new technology, called PMOS, to produce the chip. CTC agreed to the use of the new technology, but was concerned about speed to market, so they set a time limit on the chip delivery. Skip ahead a year or so.

Both chip makers have encountered new technology problems with PMOS and have failed to meet the CTC deadline. So the contracts are canceled and CTC builds the chip via discrete TTL logic and puts it into a programmable desktop terminal called the Datapoint 2200.

One of the chip makers, Texas Instruments, shelves the project. The other chip maker determines that they are approximately 85% complete on the project and that while the project will never break even, it will cost less to finish the chip, put it on the market and recover some of the costs. They do this and about a year later, a bell goes off in the financial department. The chip, called an Intel 8008, has broken even and is now making a profit. So the chip manufacturer, Intel, goes on a field trip to visit customers who are buying the chip, to find out what it is being used for. In so doing, the customers have lots of suggestions on ways to improve the chip, which Intel does and thus the Intel 8080 is born.

In the meantime, back at CTC, they have introduced the Datapoint 2200 to the market. It becomes an extremely successful product. So much so, that CTC changes it's name to Datapoint Corporation. They go on to invent another new technology to connect all of their low cost computers together. It was called a Local Area Network (LAN) and was the most popular LAN until around 1980. While the initial Datapoint 2200 did not have a microprocessor in it, it had the programmable equivalent of an Intel 8008 and it funded the initial development of the first microprocessor. Thus it is the first microprocessor based computer.

The Datapoint 2200 had a small built in CRT screen, keyboard and 2 cassette decks. There was a run light and 2 other lights on the keyboard. When the machine halted, you could not tell where in the program it had done so. So you put in the O/S cassette and rebooted. You then did a memory dump and tried to deduce what had went wrong. Primitive by today's standards, it was the first computer on a desktop.

There were also an optional disk drive using Shugart 8" floppies, single-sided, single-density. It was the first commercial computer to include them! Languages included Databus and Datashare ("COBOL-like" business computer languages, interpreted to allow multiple 80 character by 24 row dumb CRTs to share tiny partitions of RAM memory in the main system unit), a Basic interpreter, and RPG II compiler.

Datapoint is still in business, but is only a small fraction of their size in the mid 1970's

Thanks to Tom Meserole for all this info. He started programming DataPoint 2200 systems in 1972 while in college!

We are seeking information and pictures of all other Datapoint systems!

I worked for Datapoint at two production plans (Waco, TX and Ft. Worth) and the R$D Center in Plano, Texas. I worked on the 8200 line, Card Test/Repair, 1500 and 1800 lines. I liked the code names for them 8200''s were known as Jalepeño, the 1800''s were Tortilla''s. We also produced a version of the 1500 for Honeywell with their nameplate on it. At the R$D center in Plano, TX I worked on the phone switch. More specifically I worked on the Port Regulator Board. That thing was awesome. The switch didn''t work so good, but the Port Regulator was really good. I worked for Datapoint until they burned me out. When we closed the Waco plant and moved everything to the Ft. Worth plant we got so far behind on production. I would work at the R$D center for 8 hours then go put in another 8 or more hours at the production plant. We worked 7 days a week just trying to keep up with production. I was mistaken for a parts expediter because I didn''t wait for stuff to be delivered to our stations. I knew how to operate a forklift so when we needed additional boards to repair I would mount up on the forklift and go get boards waiting for repair and take them to the repair area. I knew field technicians were needing the boards as soon as possible. We would have to wait four or more hours for the expediters to get stuff to us. I wasn''t waiting for that! Man, It was good finding this. Brings back a lot of memories!

Hello All, I am trying to locate an former colleague. Her name is Karen and she worked in Product Management I think. It was awhile back (late 80s, early 90s) and my memory is a little fuzzy now, lol. Does anyone know who I''m talking about?

Worked for Datapoint from 1982 fresh out of Tech College til 1995 when Intelogic Trace filed Chapter 11. Remember the old"Wizzie " HDD''s and Cynthia drives, and the Dataproducts drum printers as well as the GE band printer$ Use to love going to training in San Antonio, WangCo school was the best!
