About Ontel OP-1 systems and Ontel company, Bob Hanrahan sent us this testimony:
Memories of Ontel, Woodbury NY
I worked for Ontel Corporation from 1979 to 1982, designing various controller boards for their line of 8008/8080/8085 based computer terminals.
The OP-1 computer family included their high end 64K DRAM system called the OP-1/64. The OP-1/64 had a 10 card backplane (similar to VME) allowing it to be configured as a terminal, word processor, stand alone computer, etc.
The OP-1/64 (also available as a downgraded version OP-1/32 or 48 for 32K or 48K DRAM) was later replaced by the OP-1/70 model. The 8080 CPU card and (2) 32Kbyte RAM memory cards were replaced with a single 8085 based CPU board with on-board 64Kbyte dynamic memory.
The OP-1 family employed a discrete DMA controller (Direct Memory Access) allowing fast direct memory transfers to/from peripheral controllers, significantly reducing CPU overhead for such tasks. For Word Processing applications Ontel provided a controller called a Word Move Controller (earlier called a Byte String Controller) which provided a method of rapidly inserting or removing characters (bytes) to/from memory for very efficient text editing.
The Intel CPU performance of that era was not powerful enough to perform these tasks using software in a reasonable amount of time. CPU based string moves for text editing would cause an unacceptable lag when an operator hit the insert or delete keys. The DMA controller performed transfers at 11 µSec/byte using a TTL based state machine. I remember designing a prototype DMA controller which moved data at 1.8 µSec/byte, considered fast for 1981! Ontel was ahead of its time in many areas, advanced Word Processing being one of them.
During 1981, the OP-1/70 was joined by a lower cost OP-1/R single board version (no card cage) which employed custom IC’s developed by the staff at Ontel. The OP-1/R (R stood for remote) looked the same as its big brother yet it could only support a single peripheral controller board, thus it was typically configured as a remote slave terminal with basic features.
Later we introduced the OP-1/50 which included 2 integrated 5.25" floppy drives with a smaller card cage in the same plastics. Finally around 1982 we introduced the OP-1/15 which was the first system to take on a new more modern look. The OP-1/15 used the same basic OP-1 backplane architecture, saving space with a much smaller and lighter switching power supply.
The OP-1 was custom configured and often custom painted for a specific customer. Large customers included Olivetti, Telefunken, CDC, would sell the systems with their own software for a specific application under their own name.
The Ontel systems were designed and built by a group of very talented (and fun) employees in Woodbury NY (Long Island). Much adrenalin ran through the company, from engineering right down to the production floor all knew we were involved with something big, something that would grow over time.
Ontel expanded rapidly during the period from 1979 to 1982, from about 200 employees (15 engineers) to about 900 (90 engineers). The founder and president at that time was David Ophire (where the system name OP-1 came from) who I believe came out of ADDS. During 1981 the company was sold from Ceasers World (owners of Ceasers Palace) to a group whose name escapes me. David and other executives were replaced by a new management team which seemed to dampen the innovative culture that existed at the time.
During 1982 we were planning to move to a higher performance (and cost) 16 bit system which was to employ new color graphics technology becoming available in new video IC’s. We evaluated the Zilog Z8000, Mot 68000, NS 16000 (later called the 32000), and the Intel 8086. Intel won, not based on performance. I don’t believe a 16 bit machine was ever sold by Ontel.
Ontel had a very strong software team who designed a very sophisticated development platform, allowing customers and third party programmers to develop system applications. The team also developed diagnostics that provided sophisticated self test and debug facilities used to ensure high quality in a system of this complexity.
The Ontel OP-1 series employed an internally developed Operating System which was ported to a tape drive during their early year, then to an external 8" floppy, and later 5.25" floppy drives. Options included large CDC drive systems for large data center applications (96 MByte total on 6 large 18” platters!).
The DOS looked much like the MS-DOS PC development platform not yet developed at that time. The team ported an early version of MS Basic, I recall when Bill Gates and Paul Allen visited Ontel to install and sell the package around 1980, kids at that time. During the peak we were selling around 10K systems/year. Around 1982 the company was sold to Visual Technology, a Boston based company who eventually closed the doors on the Woodbury Long Island facility.
We learned a lot at Ontel and I truly enjoyed the time shared with so many great people. Having lost contact with all but a few, I still think about many of them.
From my 2013 posting, forgot to mention the operations support of the OP-1 systems included troubleshooting$fixing$replacing parts: Picture-tubes, fly-back transformers, capacitors, resisters, keys, keyboards, circuit board sockets, I/O ports... pretty much anything and everything on the OP-1 !!
from Test Technician KHALID KHAN, Ontel Corp, Woodbury: 1978-80. email: email@example.com: I was a night-shift technician hired by TOM CORNETTO, the supervisor. First day I met PAUL MATULONIS a lanky bearded guy who was a very intelligent decent human being, and a helpful friend. He trained me in the schematics and trouble-shooting of the 1164 pc board, and in the use of the WETTEST software routine to check it. Mostly it turned out that boards failed because of solder shorts at back on the reverse side. Soon, we all figured that out, and became PhDs on that, and could fix ANY board without looking at the schematics or hooking up the Oscilloscope. The test floor was very social and we made good friends as well as sometimes argued too. This was 1970s New York Saturday Night Fever disco era. There were some nice chicks at Ontel. At times we used to find excuses to stand near the pc-board repair girls and joke with them and get some double-meaning answers. A real fun girl was JENNIFER STONE who talked bawdy at times and provided fun. At other times management caught some girls and guys making out in car in the parking lot. Other girls JUANITA and JESSE. The wife of one of the executives was DEBBIE BORSCINO, who was a hottie everyone noted. Among my friends was BOB SHORT, a Karate black belt under Sensei Teriyuki Higa of Okinawa Kenpo Karate School in Hempstead. Bob looked exactly like actor/body builder William Smith. Another friend was STEVE RICARDI who also trained in Kenpo Karate under master Higa. You could get a job at Ontel Corp if you just knew how a 74F74 Flip-Flop chip worked. In Long Island snow fall, going back at night at end of 2nd Shift, in my Buick LeSabre, my car used to slide sideways on the road. Sometimes, I stopped somewhere to get a 50 cent slice of Pizza and a cup of hot chocolate. Much later, I met Bob Short again in Silicon Valley in California, one day when I was teaching Filipino stick-fighting Serrada Eskrima at Tony Janovich''s Danzen-Ryu School in Santa Clara in San Francisco south-bay Silicon Valley area, when master Bob Short walked in. I eventually ended up in Hollywood working as a on-set technician at low-budget films, and at glamor films. I met many famous stars, and was personal assistant to Russ Meyers'' heroine.

Khalid Khan, ONTEL Test Technician
During the years ''78 to 80'' , I was working for the italian Company Olivetti and together with Liciano Mazzeo, I was in charge of the quality assurance of OEM products. From Ontel we have been buying a word processor versione of the OPPO.1, I travelled a lot at that times to Woodbury, almost every month, and I had the privilege to know David Ophir, Moshe Nadby, David Shiffer, Frank Kirby, Bruce Komusin and many other ingeneers which I don''t remember the name of. Everybody have been very good cooperative people and I''ve spent an unforgettable time with them from both the view points: professional and friendly. All my greetings to all the people that shares with me the memorie of the Company and of the people that worked in it. Alberto
