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 icon_biggrin.gif

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.

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 !

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.

Prudential Insurance had a Univac, it filled an entire floor on Wahsington Street, Newark, NJ. They moved up to the IBM/360. the best part of the early operatins of computer were all the key punch operators. the pretty young girls the compaines hired to do the key punching. We used to hand write all the code into coding sheets. the sheets got sent to the key punching and you got back a box of cards.

My first programming job was programming EAM 80/80 wire boards at Prudential. The key punch operators were on the 4th floor it was heaven.

I started with a IBM 370/168 6MB of main memory, and about 50 DASD (3330, and later 3350) 16 tape drives, 2 card readers and 3 3211 "high speed" printers. In the beginning no TSO, just card punching. (What a mess when you dropped that card box! icon_eek.gif
Later we added 2 more MB, and even later we added a second machine. (First SYSLPEX experience), then MVS/XA came along.

Now I'm running MVS 3.8J on my laptop, under the Hercules emuator!

In 30 years in this business, I have only seen a mainframe a couple of times.

Back in the 70s there were several terrorism incidents, so by the early 1980s the physical security surrounding large data centres was all but impenetrable. No one, including the CEO and Chairman of the Board, was allowed in the computer room unless his job required him to be there.

A computer (mainframe) operator since 1974... slept near 3330 disk-drives,
migrating, a few years later to programming.
And just a month ago, we visited a banks computer-room.
Well, the 370's and 4300 series looked much better than Z series..
