The Telcon Zorba was a late entrant into the world of CP/M portables. By the time it was introduced the Kaypro and Osborne machines already dominated that market and the Compaq, along with others, were making inroads into the DOS portable marketplace.

These factors probably contributed to the short production run for the Zorba although it's quality and it's ability to read disks from almost any other CP/M system helped it become fairly popular while it lasted.

The Telcon Zorba with the case closed

The Zorba packed up nicely into a case about the same size as the old Osborne 1.

The Telcon Zorba computer cover

The Zorba's also came with 5-sided slipcovers to protect the outer case from damage. The handle poked through the top and a strap ran under the keyboard to secure it further. There was a side pocket big enough to hold disks and some documentation.

The Telcon Zorba disks

These are the 5 original disks that shipped with the Zorba. A CP/M master, Wordstar, MailMerge, CalcStar, and more. As you can see, this machine is pristine enough to have its original drive protectors included.

The entire Telcon Zorba collection

The machine also came with a full set of manuals for the machine and the MicroPro software as well as a "Learning the Zorba" tutorial on tape.

Wow, a walk down Memory Lane.. I just want to say Hi to Bob, George, Grant, Thomas (Telcom) and Alain (Modcomp). I was in test at Telcom for a couple years then moved onto Modcomp when I had had enough of Syd and Fran, I remember Fran would walk around the plant in spandex pants and often have her hands in them scratching her backside. I very unique couple, indeed. I don't remember the name of the guy that they hired to drive the truck, their car, and do lawn work at their house. He seemed like a really nice guy that took alot of crap from the Simons. I would love to say howdy to any of you guys again... Drop me an email. I might still have a original 6 CRT hanging around, but Alain would need to get out his tube of RTV

I have a Zorba with many disks and some manuals that I'm looking for a good home for. This was my first computer that apparently cost my parents over $1000 used. Unfortunately, when I plugged it in today the screen works but it can't ready any disks (disk error 10H: Track 00, Sector 01.) If you are still interested, send me an offer.

I have a Zorba thats been sitting in the closet for about 10 years. The screen used to work but just now I attempted to boot and there was no display. When I hit reset I see a hint of text but then nothing. I have no software for it. If anyone is interested enough to send me a few bucks for shipping, drop me a line.

To Lucky----- Who are you trying to kid??? Syd and Fran were/are morons -- overbearing, demanding and rude---

The most sneaky people I have ever met..

Others followed after the Zorba came along -- (wannabe importants)

I was Vice President of Telcon for many years, and the orig designer of the Zorba and MANY other Telcon products..

Many claim to be... I have the orig schematics and proto w/w board which was created in my garage in North Lauderdale... Not by the staff who came later.....

So I read these blogs laughing at the people who claim to be the great knowledge base of Telcon Industries...

I do remember Grant -- Good programmer -- I rec a lot of early Atari games from him and information on how to mod the box to use eproms.. My sympathy to the people who came later and had to tolerate those two...

One of the first computers I programmed on in GWBASIC. Recently inherited it from my late step- dad who purchased it new. Still runs great! (Just got through reading through some old WS docs.)

Was I wearing rose glasses for a couple of years? What about everything from barbeques, showers, holiday events, birthday parties, baby showers and more? Syd & Fran kept an open door with endless encouragement & emotional support. Syd’s endless innovative & creative ideas provided opportunity for everyone to be a star. Fran keep him grounded while running the business. At times they were loud and crazy but always together. Telcon during the Zorba days was fine, the pay good, the owner's were no different than any other husband/wife business and until I read this site I thought the group I worked were excited to be part of the Zorba history. I wonder if the negative comments here have come from the green eye monster within. After all, Syd and Fran Simon were in their 40's when they sold the business based on the Zorba (still in the R&D stage) for $5 Million and retired. That was an achievement that not many can match.

I have a Zorba with all original docs. that was modified to run MS-DOS. The internal screen does not work but have external monitor that works. Also have all of the Oracle of Zeus and other manuals. I don't want to throw this computer away if someone wants it. Just pay the shipping cost and it yours.

What wonderful memories I have of this series. The disk drives were the weak link and they were proprietary, which made it awful to try to replace. The quad drives would write disks that could be read by other quads, but other Zorbas with DS/DD disks would often find that their drives would crank and crank trying to read DS/DD disks written by the quad drives. They were the BEST door stops money could buy in the early 90s!

I've been reading the Zorba comments with interest and concur with the observations on the Simons. My company is did the CPM bios for the Zorba. It was an interesting project.

I have a Zorba computer with a 9 amber screen and dual, quad density floppy drives. This was my second Zorba computer. This machine starts up and displays the Zorba logo but, as best I can determine, the floppy drives need to be realigned. Same thing happened to my first Zorba but was able to send it back to the factory to get it repaired. I would like to sell this Zorba computer along with the manuals, schematics and software.

Sid Simon and Frannie Simon what a pair they were. The previous poster is actually being polite in his description of them. The daughter was a real gem too. The biggest thrill at Telcon was when the bank would actually cash your payroll check. On more than one occasion they didn't.

(Submitted April 1, 2007 13:12:00 by Thomas Bonge)

Sid Simon was an ass and his wife was a bitch. He was about 5'6 and a fat dumpy little pig. She was about 5'10 and thought she was still the raving beauty she must have been 10 years earlier. He drove his workers unmercessly and when they couldn't work any longer she started throwing her tits around to get them to work harder. When they would walk together she would be looking down at his bald head.

But that was one FANTASTIC machine.

Anyone have a brown working model for sale?

I owned a Zorba model 7 from about 1983 until 1985. It was my second computer (first was a kit built Northstar Horizon) and a very nice workhouse. My wife used it to produce her MS thesis having it connected to a typewriter with parallel interface. If I could own another complete Zorba system, I would.

Hi, just stumbled across your page - dusting off old memories - I was a contract engineer to Sid Simon prior to the Zorba release, I wrote the BIOS and although the hardware was complete, I fixed a few things. I remember Sid always saying when will we be done? - I added the baudot (5 level) decoding capability to make it compatible with his news terminals but it took some time. A few years later a friend and I formed Advanced Concepts Engineering and made hard disk add-ons for most desktop and portable CP/M machines including the Zorba, both external and internal, 10 and 20 mb. I don't recall selling any Zorba kits, the Kaypro and Osborne were too strong by then. One other remembrance, when the first lot of Zorba cases arrived from the molder, I was in the building when they were opened and everyone said BROWN!!! expecting something more techlike. Sid's wife chose the color and nobody knew until they arrived. So brown it was. -Grant

Paul O'Nolan, I remember you from ZEUS days. I still have the ZEUS t-shirt. I did software mods for the Zorba, my first and last foray into assembly language programming.

I have a Telcon Zorba however it is slightly different than the one you have pictured here. I understand that at one time they produced a version where the drive bays and the screen were swapped, possibly to allow the installation of a larger 9 in. screen. Also the circuit breaker is relocated to the left side of the panel between the reset switch and the power connector. If you would like pics and more information on this variant, let me know. jrosstheman(at)

I had worked at ModComp (Modular Computers)with Randy during the Zorba production days. I spent way too much time gluing small ferrite magnets along the yoke of the small displays to straighten out the image. The Zorba was an incredibly labor intensive microcomputer to produce, even at that time. I just dropped off my Zorba at our local recycling center today.

(Submitted September 12, 2005 16:52:38 by Brad Mathews)

Ahhh.... fond memories! The Zorba was my second computer (after C64). I got a very early one, heavily discounted, because my computer teacher knew a bigwig at Telcon. I guess they wanted to seed the education market - I was in high school at the time. I spent most of my time with C-Basic which seemed like I finally had a real programming language to me because you could actually complile it!

I used it until 1987 when I sold it for $200.

I was given a Zorba free of cost when a left my job at Modular Computer Systems, Ft Lauderdale in the yeat 1986. I had a whole lot of problems to use that monster and finally my son in law rescued me by taking away the thing to play with it. He too got sick of it and I guess it is lying somewhere in his garage.

More.. The Zorba was solid, but very costly to produce.The cases were always a problem and took many hours of rework to get then to fit right the Keyboard in the top was my idea. But I wanted a slimmer one that could be stored in the top and removed. then the software would be stored in the top (lid) also. I was shocked to see the pictures. The Zorba died because of the costs to build it and the delays to get it finally FCC approved. I left Modcomp in 1984 and have never seen one again until tonight. Thanks for the pictures Randy

In 1983, Sid Simon, Owner or Telcon (Fort Lauderdale, Florida) sold the Rights to the Zorba to ModComp, Modular Computer Systems. The case was changed from brown to Black. I was surprise to see the brown one, When I worked there (Telcon), only been a few dozen of them had been sold. By the time Zorba was sold to ModComp, I was working as an engineer with Modcomp and dreaded the day I was told that we would be required to make the Zorba FCC compliant. The only way to do this was to coat the inside of the case with an RF shield and to have a special AC cord made. the AC cord was designed by an associate of mine Vern Hargeaves, who also worked at Modcomp. The Zorba was sold to Modcomp for 5 million dollars. I was in charge of the video portion and getting the CRT's to work. we had tons of them that we had to glue (RTV) magnets to the tube just to get the text straight. More later... Randy
