Hello and welcome to the forum,

Suggest you talk with someone in the Computer Operations group (or your manager) and ask for a bit of a tour (if your office is somewhere near the computer room and not a remote site).

Hi Dick,

She is from Pune (a city in India), a "tour" seems to be a distant dream.

However, she might try to get in touch with CDAC or Maple (local Mainframs coaching cetnres) they have got their own Mainframes, I've heard.

Hi Anuj,

Yup, i knew Pune is in India, but not that this would be a remote site

I've been some places where the IT staff is "just down the hall" from the data center and most of the people had never seen the inside of the computer room.

started on a 370/125, worked on 3033E, serial number 000002 - so many ECs (engineering changes) that it didn't have doors on it because of all the wires going from one frame to the next. Then countless boxes after that. Only ever saw one 360 in production on a manufacturing line. Used 3084 TCMs as paper weights. Mainframes were just big boxes. Now they are just small boxes.

Hi,

I started with MVS 3.7 on a 370/158. Most beautiful machine I ever saw was a 370/168 MP. Storage was on 3330 and tape was the reel stuff on very real units. Did a lot of working with punched cards, too.

Must admit, it's been some time sincs I actually saw a mainframe. Not that I actually miss it. After all, nowadays they're just as nice looking as a fridge.

Funny,
for all places I worked with VSE, the answer is YES,
and for all places I worked with MVS, the answer is NO.

so after all going from the 3080/3090 ( water cooled series ) where there was a chance to use it as a refrigerator
to the new technologies, was a step backwards, not forward

and the piping was quite sophisticated, all the pipe junctions were with safety valves
( You could attach and detach everything with the water cycling at full pressure with just a few drops of water )

1976

IBM 360/40 - 48k main storage (carbon core - pre transistor) running DOS - no screen, just golf-ball tyewriter for Master Console printing onto lineflow. All punch card input. IPL's involved a large blue button with IMPL written on it! All the red checklights would go on on the facia if a vacumn cleaner was started anywhere near it!

1977
IBM 370/125 running DOS POWER/VSE. Luxury of a master console screen. Non luxury of tray after tray of card input and endless prinnting of multi-part lineflow paper on a 1403 followed by decollating it.

1980 - for a few years.
370/158
370/165 (with crap CDC memory upgrade)
3031's
3081's - started installing channel cables at this point as well. Shit job pre fibre as the old grey and blue copper bus/tag cables VERY heavy, especially for 3420 drives as that had extra shielding.
3084
then some Hitachi's..can't recall the model numbers
3090's of various flavours

Now miles away from datacentre so never layed hands on any of the Z990 or Z10's, but they're pretty boring to look at these days.

I go back to 1401/1410's and 7094's so over the years I have actually seen probobably all of the 360's and 370's (except the very rare 360/95 and extremely rare 370/195 pipeline processors) most of the ES9000's and many of the early CMOS IBM's. I have seem several 800's 900's and z9/z10's. Have not seen a z11 yet but the consulting company I am with is working on capacity/performance issues for a State government right now and I may end up recommending they look at the z11's - not sure - project is just getting going and I haven't finished data collection.

Hi All,

I am not a Developer but the end user of ISPF (Focus). Struggling very hard to learn how things work.

First MainFrame? A Honeywell Dinosaur in 1970. Then, a bleeping 360 running MVT. Then IBM 370/168. Then a 3033. Then a 3091. (Yawn) So many allnighters.... back in the day, doing CICS installations and testing and coordinating with the VTAM Clowns. Oh what fun! (Nah, am Serious: It WAS Fun) And doing prohibited things (Late Night) was a total blast !

Michael Mays · Posted: Fri May 07, 2010 12:42 am

Mainframes have come a long way.
When I started in 1970, we ran 160 grocery stores on an IBM 360/20 with 8K of central storage. No disk, No tape.

Those were the days when men were Men, and machines were Machines!!<G>

That same operation now takes a computer at least a thousand times more powerful to do the same job.

My first was an IBM Z9 Enterprise Class on in November 2009.
