1980's to 2000. I just read through your page. This recalls almost immediately all the Residencies in Raleigh from the 1980's to 2000. ... the IDNX, Token Ring LANs, IBM Routers, 2220 Frame Relay & ATM Connectivity, Network Utility and ..... All these Residencies were great weeks/months for me and will always be in my memory. I'm retired since January 2010. Here in IBM Switzerland, the "official" retirement age is when you finished 62, so my retirement was regular, not early retirement.

On the technology side, I'm keeping my various computers at home up to date. The 2 main projects are:- I'm running an Asterisk, a full function PBX in software on a 6-Watt mini-PC  (Linux open source) for my IP Phones at home - and, working on new HW and SW to control my heating system. The current controller is more than 20 years old and uses dbase which needs to be replaced as well.

Upcoming:  I may teach a few CISCO courses. The courses are all 1-week courses.

Updated discussion: August, 2019 .... Martha and I and the families of our two daughters are doing well, we are grateful for that.

At the moment I am also busy with the preparation work for the replacement of the heat pump. The old heat pump ran smoothly for 39 years and has more than 50,000 operating hours. It is still running, but making sometimes an unhealthy noise and the efficiency is of course by far not as good as the new machines and so I will replace it in the near future.

To IBM, I have almost no contact with the exception of our old network team. We meet every two months near the IBM building in Zurich in a pizzeria for lunch. I often think back to the residencies in Raleigh ...   There have always been wonderful times. ….

Comment from Dave Shogren:

(Heat Pumps): We had gas in Minnesota (so, rarely air conditioning).  When I moved here, my friends explained that normally the houses have “Heat Pumps” and I said “What is THAT” and they explained that the heat pump was also for air conditioning – and, you will need to replace such every 15 years if you get lucky – and: They were correct: One made it 15, one made it 12 and we are now on our third.  50+ -- you have been very fortunate (however, I know you do things yourself and get things done correctly).  Good luck with the next 50+!

From Gallus:

Regarding the heat pump: yes, I have been very fortunate that the pump ran smoothly for 39 years and is still running. Here they usually give them around 15-20 years as well.

I remember, (It was in the last millennium) a few months after we had installed the heat pump, I was at an exhibition and met there a heat pump service technician. I asked him: if a heat pump is defective, what is broken most? He said without thinking: the electromotor if it is not equipped with a soft-starter. Then I went home and developed and installed a soft-starter. That certainly contributed to the long service life as well.

1982 & 1986-thru-1989. It's nice to have some words in the Internet to remember some period of our common life.
  • Rowan str. Building 622 In 1982 .... Tape Reader/Writer on a 360/40 working in DOS!
  • And of course between 1986 and 1989.

I am still in touch with Jean-Louis P.

Say hello to your family and friends; ... the best of my memories.

Stay tuned, if you are interested! In the meantime, thank you in advance for contacting me - if you have memories of!

1985-1988 I am happy that through this site we will be able to renew the relationship we had with you and other assignees working for the ITSO. I started my assignment in August 1985 and stayed in Raleigh for 3 years. The work in the ITSO is considered as the most beautiful time my family  and I had. Short time after returning from Raleigh to Israel I accepted a package, retired from IBM and moved to South Africa and stayed there for 3 years.

Since 2006, I participate in residencies at the Poughkeepsie ITSO writing communications server Redbooks and "The new mainframe Networking text book."

Today, I act as an independent consultant in the area of IBM MF networking.

I participated in 4 residencies in Poughkeepsie ITSO writing Redbooks.

Early 1980s We worked at Rowan Street in the early 80's. For me, it was Token Ring and OSI. Those subjects have kept me busy for many years beyond my assignment. In the 1990s I worked for AT&T-Unisource Communications Services (AUCS).

Eventually, (again, in the mid 90's), AUCS was sold to Infonet. From then on I was asked to perform systems and network simulations for them (Infonet). The tool was/is supplied by Opnet. (refer to opnet.com).

After a couple of years of serving interesting customers and their misbehaving (slow) systems and poor response times, Infonet sold their Services Business to Vodafone. After that, I was in their training dept. In the middle of the that I left the company. At that time I was 61. Vodafone scrapped the simulation business 8 month after I left.

Next, I worked on my own, with the Opnet tools. Very costly though!! It was/is difficult for customers to subcontract to me and to pay for the Opnet tool as well.

So... since 2002 I am freewheeling. After a year or so, from approx early 2004, it means voluntary work. Mainly helping people with their PC problems and driving seniors whenever they need a ride to their appointments. All that (computer-services and voluntary driver services) is organized by the Bennebroek Community.

Aug 81 - Aug84 and various others (even back into the 1970s). I (even) remember lunchtimes at the 'Deli King' with suitable fondness and lack of clarity. Token-Ring IEEE 802.5, SNA PU type 2.1, APPN,  SNA LU type 6.2 and APPC. My first interaction with WTSC Raleigh was with Dave Shogren and Snap/Shot. My job at that time was predicting network and systems performance using a number of tools including simulation and analytic techniques. This was in the 70s, about the time of the infamous Five vs Snap/Shot discussions or wars. Influential to me at the time were Dave Shogren, George Bachouros, Jack Harris and my UK colleague Richard Revell. I enjoyed that so much I applied for a 3 year assignment which began in 1981.

My WTSC Raleigh Mgr, Jack Miess, suggested I switch my assignment from performance modeling to then emerging LANs and peer SNA protocols and products. I agreed and floundered for many months before gradually finding my feet with help from Dan Pitt and Dan Warmenhoven out in RTP, Harry Dutton (an Australian WTSC assignee), and Patrick Abbott and Luke Wilson from UK FSC. I had few residents; but, Gerard Joseph from Australia did sterling work on the APPC redbook and immeasurably helped my understanding. Again, I have to mention the "Deli-King" and our business lunches there.

Later-on, I sang for the 'Hughe Grunt' blues band from 1998 to 2007, playing mainly pubs and village halls in and around Hampshire and South West London, and I'm very proud of a 7 track CD we recorded in 2002.

I finally took early retirement from IBM in January 2003 to work with my daughter, son and son-in-law running a number of 'gastro-pubs'. Needless to say my experience as a customer of the 'Deli King' helped enormously in this regard!

I also remarried in 2003. I left the world of work altogether in 2008, and in 2009 my wife and I emigrated to Dublin, California where we now live. My wife works for Cisco in Advanced Services, and I keep house, visit wineries in Napa, Sonoma, Paso Robles and Livermore Valley, entertain friends and family when they visit, and try to keep up with my 3 kids and 5 grandchildren.

1992 and 1993. I can’t forget the 2 short stays that I spent in Raleigh in your team. Wonderful experience - and I also remember your good wines. I left IBM in 1996. After that I came back to the university: In Fribourg ( Switzerland) for 3 years : The study of exact sciences had led me to work at IBM. After, the time came to study human sciences.

My wife Mijo is still working for PTC (American company based near Boston). We are living in Palaiseau, 20km south from Paris.

Our daughter spent one year in NY and at the end of her stay we made a tour in the west of US 2 years ago.

Now, I work as a psychoanalyst and also as an associative volunteer.

I am travelling, almost every year in Indonesia and Philippines. Two years ago I traveled in the west of the US. .

Thanks to my exercise bike I keep a good shape.

1970s-1990s. I remember very often on the nice time I had at the WTSC Raleigh and at the SNA lab in Raleigh around 1979. . I left the company (IBM) in 1996. My last IBM job was product manager in Germany for AIX-SNA  products.

After, I worked at a network company as business partner of AT&T, which was the owner of the IBM network. We sold and installed the network connections for a lot of customers with the IBM routers and the terrific speed of 64kb, or a multiple speed up to 256kb. It was the time when SNA was gone!

Now, I enjoy the life as a retiree since 2004.

I still have a connection to Raleigh - since 1979 when I did interesting work at the SNA lab. I had to program the Maintenance Device to test the 8100 Loop. All the guys told me that this will not work until Joe Jarvis came and he said, it’s no problem: We only have to change a little bit of the micro-code. Indeed, it worked fine and since then we share letter communication.  

Now, at the age of 74 I married again (My wife Ute passed on in 2009 of cancer) to my new wife, Charlotte who lived for several years in the US, mostly in New Mexico. During the last 5 years we made very nice vacations with an RV around the Rockies visiting many of the nice National Parks. This year we will make a tour around the South East states.

San Jose and Raleigh
1980 San Jose - the IMS/VTAM interface with Irmgard Stelkens

1983 Raleigh - SNI for Eddie Kaufmann with Karl Rentschler

I returned to the UK in October 1993 just in time for an early retirement package, leaving in Jan 1994. Soon afterwards Fritz wanted Netda/2 help for a German Army project so I worked for IBM Germany's Consulting Group for some weeks in 1994. On an expenses basis I also spent a several weeks in Raleigh over the next few years to work on Netda/2 with development.

Our daughter is married and lives in California so most years since retiring we've had trips to and around the USA. Like Harry Dutton I have an interest in family history and looked after the Sussex Family History Group's website for about 12 years in addition to one of my own.

I discovered racquetball on a 1980 residency in San Jose and played in Raleigh regularly with Roberto Chamoun until he returned to Brazil, and also with Jorge Ferrari and Dave. On returning to the UK I took up the UK version, slower ball and played on a squash court, but my hips told me to retire at 80 as the pandemic arrived.

I keep in touch with Gail, Dick, and occasionally Jorge.

Dick Hippert was my manager until he retired in 1991 and then ... . I took over Ross Leighton's slot, and some of his furniture, and worked mainly with Fritz Pfrang and Francisco Gayo and Roberto Chamoun in the Network Design tools area. The last product I worked with was Netda/2.

The opportunity that you and Barry gave me in Raleigh were really important to me. I remember adding it to my resume ("International experience") and most of all I cherish the opportunity to interact with people from all over the world.

1993 (I think...) My specialty was networking and I worked on NetView/6000 redbooks both times. My mentors were you (Dave Shogren) and Barry Nusbaum.

1994.... On my second trip, I worked with Jerry Badalassi from Australia

I left IBM in 1995 and my career took different turns but always related to the tech industry (telecom, cable TV, cybersecurity) in various companies: Motorola - my longest tenure, Accenture, Arris, Nokia, and now, Fortinet.

Early-Mid 1990s

I attended a couple of your classes on NetView/6000 and a residency at Raleigh during the 1990s.

Note back to Ban from me (Dave Shogren): In fact, I think of you often (as I drive past the “Navaho Drive” and Wake Forest Drive (near the beltline of Raleigh) and remember your staying in a hotel in that area (and, of course, the wonderful restaurant lower-level of one of the buildings; the restaurant is long-gone now) – and, your/my discussions (I can’t remember the discussion topics – but, I KNOW you/I had good discussions and projects). All good memories.

Memories fade – but, general matters continue and you are part of that memory(ies).

I was posted to Plano, Texas last year 9/2023) and have always wanted to take a trip to Raleigh for precisely the reason you state - All good memories indeed.
