Despite its nice and rational design the keyboard was unsuitable for an intensive typing.\
Notice the small template on the numeric keyboard which allowed to use the numeric keypad for dialing.

I worked at Convergent Technologies from 1980 until 1991. The Workslate was notable as an early user of surface-mount technology. It was Convergent''s first use of SMT.
The Workslate is also notable because before its introduction, Convergent could do (almost) no wrong. Everything we made sold like crazy. After the failure of the Workslate and the almost simultaneous failure of a customized Unix workstation for AT$T, it seemed we couldn''t do much of anything right. The company was sold to Unisys in 1988 and most of what remained of it was disappearing by the time I left in 1991.
Despite all that, the Workslate was a remarkable first step into tablet computing. If it had offered BASIC programming and had a word processor, it may have succeeded. (It is hard to imagine, but in 1985 people really, really wanted BASIC$ and the inclusion of a word processor was considered too premium at that time.)

I was a Convergent OEM in the early 1980's. I have a complete WorkSlate system including the Parallel port adapter and battery pack (needs new batts) I even have the classy leather poutch.\
I bought it new for $1200 and I was an OEM. Convergent really screwed up on the marketing of this product. Some genius talked Convergent into marketing this totally new product through American Express instead of their OEMs. How dumb was that? If they had gone to the OEMs they would have sold a ton.
If you notice the keyboard has a "DoIt" key. The President of the fledgling company Allen Michaels used to roam the halls of the company at night and spray paint "DoIT" everywhere, hence the key name.
Mine still works but boy is it slow.

The Workslate was my second computing device, the first being a Tomy (toy) computer which allowed rudimentary Basic programming and little else.
I bought it cheap in 1984 and used it extensively for a couple of years until I replaced it with another orphan, the Pied Piper, which was light years ahead on account of its 1.2 mB built in floppy drive and the ability to add an external one.
As opposed to the so called portable Osborne, the Workslate was a marvel for its time, comparable to a netbook (my preferred device for the past 4 years) in terms of portability and also sufficient functionality.
I used my WorkSlate as a remote terminal for EaasySabre, the Library of Congress and as a smart terminal for Western Union''s foray into document delivery which was a sensation at the time, years before FedEx also failed with a similar gambit. Instead of buying a crappy and expensive dot matrix printer, I used to send everything over the 300 baud modem and Western Union would print out contracts on laser printers that almost nobody else had at the time and mail to specified recipients. Yes, you could save a contract or 2 to the microcassette drive!

I first heard of the Workslate when it was on the cover of Mexhanics Illustrated. The following year, I purchased two of them for the company that I worked for. The outside representatives could use them to do calculations while at a customer''s location. No other portable computer existed that would allow this. I created several master spreadsheets that utilized the upgraded 50k memory.
Due to the limited memory, I learned how to created a compact, efficient spreadsheet! As supurvisor, I kept one at my office and the other one was used by my only rep that i could trust with a computer at the time! Those two units, especially the one I used, were used up until 1992 to run the speacilaized spreadsheets I had created and maintained each year with updated information.
When my position with the company was eliminated in 1992, the spreadsheets were recreated in Excel on a desktop computer and the Workslates left the cmpany with me. I supsequently sold one of them to a person in NY whose unit had died and he wanted to replace it for the speacialized application that he used his for.
I still have the other one and the portatble printer that was made for it. It was a "spreadsheet in a box" and worked well for that application. And, yes, it had character!
Thanks for the memories!

Someone asked about determining the polarity of the NiCd battery for the Convergent Technologies Workslate.
The NiCd battery I have is a WK-101 4.8 V 500mAh. It measures 4 1/16" X 1 1/4". As you view the battery there are a series of arrows on one side with the label "This side up". When oriented this way on a flat surface and the arrows pointing North (or away from you) the polarity markings are on the end toward you with "+" on the right and "-" on the left. There are no other polarity markings. The battery is made up of four 1.2 V cells connected in series. The end oppposite the end with the markings is open and and the cell ends are exposed with the "-" end of a cell on the right and the "+" end of another cell on the left.
The AC adapter is supposed to charge the NiCd battery when the battery is installed in the Workslate.
Hope this helps.

text: I have one I purchased way back then, printer and all. It''s still one of the coolest computers ever made. It was very ahead of it''s time. One of the reason (IMO) that it failed was a lack of IBM PC compatibility. That was the direction everything was going, aside from MAC of course. Another cool computer of the time was the GRID. Good times...

In an episode of season 1 or two they do a quick 2 second shot of him typing and you''ll see it.

I have one of these I am looking to pass along to a good home. It is complete with the printer, hard case, cables, two packs of un-opened color ink styluses, and 9 tapes with programs, one or two even in the original shrink-wrap.
It is basically in mint condition - although I have not had time to power it up. Also have a branded binder with the user manual for something called TransSlate which apparently is a method to tie the WorkSlate to an IBM server.
I am not looking for any money other than the true cost of shipping. If interested, let me know!

Back in 1982 or '83 I had a Sord IS-11, which had a 25x80 screen and a decent word-processing app. But when I got one of the remaindered Workslates -- was that '84? whenever the prices fell -- I sold the Sord to get the Workslate. The keyboard was pretty funky, and the word-processing made no sense whatsoever, which was not the best thing for a freelance writer, as I was at the time.
But it had an aesthetic that I remember to this day.
Actually though, I realized a little bit ago, after being reminded of this machine, that it had so many limitations in its vision that I've also lived many a year without thinking about it. Some of it -- the green and yellow labels popping off the black, the marketing by cool factor -- was timeless. But competency and utility from more mundane solutions is a good idea too.

text: I first saw a Workslate when I was living in Hawaii - too expensive for me then. I later bought one from DAK (or similar "surplus outlet" store, probably for about $100. It was my second computer, after a Timex 1000. I really liked the 1-2-3 metaphor which helped me with contract pricing negotiations. I started lugging my original Compaq to those sessions and didn't use the Workslate, giving to a friend still in Hawaii. Wish I had kept it! I'll look for the original ad or receipts, which I probably still have.

Convergent Technologies of Santa Clara, California introduced the Worslate the same time as the Tandy [Model 100](/museum/tandy-radio-shack-trs-80-model-100-102/). Although it was about the same size of the Model 100, the Workslate was primarily a spreadsheet machine. No other software could be loaded except some application which was adaptations of the basic spreadsheet program.
The Workslate used a CMOS version of the old 6800 processor and 16B KB of RAM. RAM size couldn't be extended and allowed a limited 720 cells spreadsheet to be filled. The keyboard with circular rubber-keys was hard-to-use for text entry. However, with its phone book, memo pad, and financial calculator, the Workslate was designed for those who only wanted a business tool and didn't want to learn about computers.
Also built-in were a tape drive able to record and play data's or voice annotations, a 300-baud modem and a printer port.
The Workslate was first launched in the American Express Christmas catalog, and was sold as a high-tech novelty product. But no one was interested in buying a limited spredsheet machine for $895. Convergent Technology planned to sell 200,000 units within a year, but only 5,000 systems were sold in the U.S.A plus some hundreds in Europe. The product was discontinued in July 1984, and the company lost about $15 million.
If you notice the keyboard has a "DoIt" key. The President of the fledgling company Allen Michaels used to roam the halls of the company at night and spray paint "DoIT" everywhere, hence the key name.
