What model of IBM 370 computer was used at Human Genetics to run MTS? A 4341? A 4331? Something else?

Do you remember approximately what year the HG system was installed?

What role did the Computing Center play with the HG system? Did it maintain MTS? Anything else?

My memory on all this is very vague. I think it was a 4341, but hell if I can remember the dates. I think I consulted with them a few times, but don't remember being actively involved in the maintenance of their system. I can't find anything in my email archives where I communicated with the guy at HG (Paul Kopec) about anything MTS related.

I can confirm that it was a 4341 but I don't remember the dates.  It was around the same time as the switch to the 3090.  I thought that there was a note in the CC newsletter shortly after it was installed.  I found a reference to it in the index for Volume 2 (4:16) (which would be 1986, I think) but I could not find the actual newsletter issue online.

We managed the system - all software updates, reboots, etc.  I do remember that MTS didn't have a way to change to/from daylight savings time without a reboot.  I went over once on the Monday after the DST switch to reboot it and discovered that it hadn't been rebooted since the previous DST switch.  I think that it was still running when I left in 1989.

As I mentioned to Jeff in another message, I have an EMail archive of 367 messages related to HG.  I sent this to Jeff, I can send it to anyone else who wants it.  Here is a relevant message:

Subject: Machine configuration
To: Andy.Goodrich@um.cc.umich.edu

I have a tentative hardware configuration for the IBM 4361 along with a
tentative budget. I would greatly appreciate an evaluation by you and your
to make sure we are in the right ball park. We are pushing our budget a
little depending on the final discount from IBM. We were given a 44%
discount on the first try but it might not be as great this time due to
the exclusion of the operating system. One item that is not included
but should be considered is the Resource Manager. Steve Peterson from
Simon Fraser would be glad to help us get it going and we could include
some money for his assistance. I believe he estimated 3 weeks time. It
is my understanding that we could live with HASP for a while under the
proposed configuration if we are willing to sacrifice .24 gb disk
space for a spooler (ugh!). Depending on the estimated implementation
for the RM at the CC I believe I would rather wait and be running
the same version of MTS as the Center.

I also have a long message from Jim critiquing this configuration and suggesting alternatives.  I didn’t yet find one giving the final configuration they got, but it’s probably in there somewhere.  My EMail archive from that period is fairly complete.


And from Mike Alexander's e-mail archive:

Date: Fri, 7 Feb 86 11:28:34 EDT
From: Thomas.D.Berry@um.cc.umich.edu
Subject: Human Genetics
To: Jeff.Ogden@um.cc.umich.edu

At the Department of Human Genetics we are in the process of replacing
our PDP 11/70 computing system. We are considering either an IBM 4361
model 4 running VM/SP or a VAX 11/785 running VMS 4.2. Because this
facility will be supporting researchers from different parts of the country
(and different countries for that matter) we would like to do everything
possible to ensure the best possible link to the network. We presently
have two SCP's (11/23) which we are using to connect the PDP 11/70
and VAX 11/750 to the network as async hosts. I have worked out the
details the VAX 11/785 connection but I am unclear as to the options
for connecting the IBM 4361. At a recent IBM presentation Kathy Edwards
mentioned that you were working with the University Libraries to connect
their IBM to the network. We would be in a position to consider the
purchase of a PCP if that would increase the ease and/or functionality
of our connection.

                Thanks for your help

#3: IBM 360/40 at ISR

posted May 14, 2019, 4:59 AM by Jeff Ogden

When was the IBM 360/40 installed at SRC/ISR?  Was it purchased or leased? What OS did it run, OS360, MFT, MVT, DOS, something else?

I’m working to fill in a timeline of mainframe computers at U-M.


On May 10, 2019, at 6:49 PM, Gregory A Marks wrote:


I cannot think of any documents I have left that would provide those details with certainty. I can deduce likely dates from the following:

I started work at ICPSR in 1964. I think the NSF funding quest started in 1965. The 360/40 arrived once the new ISR building was occupied in 1965. It was in place for a period of time, maybe a year or more, before the 360/67 arrived at the Computing Center - my recollection about that is fuzzy. The timeline at https://isr.umich.edu/about/history/timeline/ suggests a 1967 installation, but I would guess earlier than that. So my best guess is 1966, but it might be early 1967.

I recall only that it was the simplest form of OS/360. Looking at the Wikipedia piece on OS/360 at https://en.wikipedia.org/wiki/OS/360_and_successors I would conclude ISR had the simplest, OS/360:PCP which handled a single stream at a time.

ISR had a tape-based 1401 before the 360/40. As I recall, the nature of the job queue being one job at a time, first-come, first-served was the same with both systems.

I am planning to clean up a lot of old boxes of accumulated stuff during the summer. I think I threw away most of my ICPSR stuff about 20 years ago, but if I find anything relevant to your question, I’ll let you know.

Kudos to you for doing this work, Jeff.          All the best.          ...Greg

Thanks. Someone said that they thought that the 360/40 at ISR was used mostly as a remote batch station to MTS. That didn’t jibe with my memory, but I wasn’t around yet (I arrived in Ann Arbor as a freshman in the Residential College in the fall of ’68, took my first computer class in ’69, didn’t take my second one until ’72, and went to work for Interface Systems later in ‘72) so anything I know is at best second hand.

I suspect that the 360/40 was used as a remote batch station at some point as well as for running jobs directly. I’m guessing that a lot of those jobs were OSIRIS. Later the 360/40 was moved from SRC/ISR to the UNYN [a public site in the Michigan Union by the U-M Computing Center] where it was a full time remote batch station. The fact that the U held on to the 360/40 for such a long time makes me think that is was probably purchased rather than leased.


On May 10, 2019, at 10:47 PM, Mike Alexander wrote:

Thanks, that’s earlier than I thought.  I doubt that it was earlier than mid 1966 since there were very few , if any, 360s in Michigan then.  When I needed to test the code for the 360/50 we were getting I had to go to Chicago to find one that I could use for testing.  I’m quite sure there wasn’t one in Ann Arbor then.  That was in April 66.  This is consistent with Greg’s recollection.


#2: Timeline of mainframe computers used for academic computing at U-M

posted May 6, 2019, 6:37 PM by Jeff Ogden   [ updated May 15, 2019, 3:22 AM ]

1953 -- MIDAC operational

MIchigan Digital Automatic Computer becomes operational (August). MIDAC was operated by Willow Run's Digital Computation Department under the leadership of John Carr III. The project was under the sponsorship of the Wright Air Development Center, United States Air Force and the Willow Run Research Center of the Engineering Research Institute, University of Michigan. MIDAC remained the property of the Air Force until it was removed in 1958. [UMRNews76]

1956 -- IBM 650

The IBM 650 was installed in the Statistical Research Lab. [UMRNews76]

1959 -- Computing Center established

A "research and service activity of the Graduate School" and was intended to "provide consultation and computing service for teaching and research units of the University." [UMRNews76]

1959 -- IBM 704 purchased

The first computer installed at the Computing Center is for at least some operations 100 times faster than the IBM 650. [UMRNews76]

1961 -- IBM 709 installed

The IBM 709 computer at U-M's Willow Run Laboratories is transferred to the Computing Center in January and moved to the North University Building in August replacing the Center's IBM 704. [UMRNews76]

1962 -- IBM 7090 installed

A transistorized, or solid-state, version of the 709, but six times faster, replaces the U-M Computing Center's IBM 709. [UMRNews76]

1963 -- Computing Center moved

Reporting changed from the Graduate School to the Office of the Vice-President for Research. [UMRNews76]

1966 -- IBM 360/40

Installed at the Survey Research Center within ISR to replace a tape-based IBM 1401. Ran OS/360 rather than MTS. [GregMarks19]

1966 -- IBM 360/50 installed

As part of U-M's CONCOMP Project an IBM System 360 Model 50 is located at the North University Building (NUBS). This system is used to support peripheral operations for the 7090, development of a IBM channel interface for the PDP-8 Data Concentrator, and for early MTS development work (May). There wasn’t room in the machine room for both an IBM 1410 and the 360/50, so the 50 had to take over the work of the 1410. [UMITD96]

1966 -- IBM 360/67 installed

This single processor system was eight times faster than the previous IBM 7090. The 360/67 was the first IBM mainframe to support virtual memory and other features to support time sharing. Serial number 2. The IBM 360/50 was removed when the model 67 was installed. [UMITD96]

1968 -- IBM 360/67 upgraded to two processors

The U-M Computing Center obtains a dual-processor (duplex) IBM S/360-67 (August). It replaces the earlier single processor 360/67 which was designed to be field upgrade-able, but in fact was not. The original plan was to upgrade the half-duplex 360/67 by adding a second CPU.  That’s why U-M got the half-duplex instead of the slightly cheaper simplex model 67 initially. In the end, IBM decided they would rather replace the whole half-duplex 360/67 rather than try to field install all the fixes that hadn’t yet been installed on the half-duplex.  It was going to be a major job to install all the fixes and the result would probably be less reliable than a new machine.  So MTS was shut down for a weekend and IBM moved out the half-duplex and moved in a duplex.The IBM 7090 was removed earlier to make room for the duplex 67. [UMITD96]

1974 -- IBM 370/168 installed

Installed at the end of fall term 1974, the 370/168 was, on average, six times greater than that of a single processor on the 360/67.

1975 -- Amdahl 470V/6 purchased

Installed in July the new computer is on average between 1.6 to 1.7 times faster than the previous IBM 370/168 mainframe. It was the first mainframe computer purchased by U-M, the previous mainframes were leased. Serial #2. Main memory increased from 2 to 4 megabytes in July 1976, from 4 to 6 megabytes at the end of December 1977 and from 6 to 8 megabytes in November 1978.

???? -- Amdahl 470V/6-II upgrade

The 470V6-II offered up to a 15% performance improvement over the original 470V/6.

1978 -- IBM 370/148

A system used by the IBM sponsored Word Processing Project, it ran MVS rather than MTS and was not generally available to campus students, faculty, and staff.

1979 -- Amdahl 470V/7 purchased

An Amdahl V/7 with 8 megabytes of real memory that was 50% faster than the Amdahl 470V/6 it replaced in March. Real memory was increased to 12 megabytes early in 1980.

1980 -- Amdahl 470V/8 purchased

The Amdahl 470V/8 replaced the V/7 and provided 10% to 15% additional capacity. Real memory on the system was increased from 8 to 12 megabytes. In September 1981 real memory on the V/8 was increased again to 16 megabytes.

1982 -- Amdahl 5860 purchased

Serial # P1 (first production machine) began production service in November. The 5860 provided a 40% increase in processor capacity compared to the 470V/8 that it replaced. The new system had 24 megabytes of real memory.

1985 -- Amdahl 470V/8 installed

This system was donated by Amdahl and became the second MTS system in March, called UB. It had 16 megabytes of real storage.

1986 -- IBM 3090-400 approved

A four processor system with 128 megabytes of main storage, 64 I/O channels, and two IBM Vector Facilities (VFs) with an option to add a third VF at a later time. The first factory shipped IBM 3090-400 was installed in October. Each 3090 CPU is roughly 1.5 times as fast as an Amdahl 5860 CPU. The 3090 replaced both the Amdahl 5860 (UM) and the Amdahl V/8 (UB). To continue to run UM and UB as separate systems the four processors of the 3090 were often partitioned into separate systems with two processors each with one partition often running under VM/370. [UMCNews86]

1987 -- IBM 4361 Model II

The U-M Department of Human Genetics ran MTS on an IBM 4361 mainframe starting in January or February 1987. U-M's academic Computing Center maintained MTS, performed software upgrades, re-IPLed the system, and did trouble-shooting as necessary. [UMCNews87]

1988 -- IBM 3090-600E upgrade

An upgrade to a six processor system with two Vector Facilities was completed in July 1988.
