This is a poll, please Vote.
As a Mainframe programmer, have you ever seen a Mainframe - the Big Iron / Dinosaur or even the new s/z-series!
Please don't lie, just vote from heart. |

Yes, a 4381 and later a 3090. I used to have tape-reels with test files in my drawer.
I even survived a VSE to MVS migration! Logging off my VSE session on fridayafternoon and logging into MVS on mondaymorning. I did not realize at that time how unique that experiance actually is. And, after working with iccf, I really, REALLY like TSO! |

I got opportunity once and it was wonderful experience.
It has even robot shape moving element inside which we can see while retreiving the archived element..dataset when you try to restore
I can't explain in words and never forget that experience |

Yes robot arm actually..to mount/move tape dataset, as tapes are not permanently in 'service' of Mainframe ulike DASDs. |

| For a long stretch of time, no. The datacenter was located remotely from where we all worked, and access to it was strictly limited. Recently, at a newer company, I've been to our datacenter a couple of times. Got to touch it and everything. |

| My first one in 1967 was the Honywell Bull Gamma 10 using relais. After that Control Data Corporation CDC3300 and CDC3500 followed by IBM's 360, 370 and a lot of successors. Even returned to the floor a few times to operate while being a project manager while the operators were enjoying a nice dinner I had them brought during an implementation. |

| I started programming in 1966. That's all we had were mainframes and programmers ran their own jobs. It was a 16K machine. |

I agree that it has tapes but it's a production mainframe server which I have seen in Melborune in Mainframe datacenter.
It's about 7 ft height and 4 ft width and don't know it's one of the best exp i ever got as a mainframe professional |

| My mainframe history goes as follows. IBM 360 Model 40, IBM 370, IBM 4361, ES 9221, Multiprise 2000, MP 3000. That first 360 had 256K of memory, with an additional 256K in a standalone box next to it. We ran DOS. No spoolers, no Queues, nothing. You read in a card deck and the program would run. You had to pre-load the printer with any special forms required as when the program wrote to the printer, it wrote TO THE PRINTER. 800 FCI rated tape drives. 2314 disk drives. Card decks galore. Those were the days.... |

rich customer You had
my first one was a 360 model 25 with 16 kb of central storage
card reader
card punch
line printer
2 x 2311 disks 7 mbytes each, made for humans... 100 cylinders 10 tracks per cylinder
the card punch was a price trade off
to run sort the supervisor had to be reduced to less than 6 kbytes,
and the only way to do it was to take away the dasd supprt for sysin/syspunch
and real storage was much more expensive than a card punch...
so when cataloging the object of a subroutine
the first step was to run an assembly with object deck ( punch not spooled )
take the deck, for large assemblies better not to have the soap bar syndrome
compose a new card deck with the proper CATLR card
put the thing in the card reader
a real pain in the *** |

but I bet my cpu list will beat all 
ELEA 6001 amazing decimal mainframe with
variable length instructions and variable length operands
each byte had the usual stuff + parity bit + the stop bit
the instruction address part was written in reverse order so to save space,
the unspecified digits were taken from the previous address,
the register were standard memory location,
to save the full range of register You simply had to point to a different storage location
it was built by OLIVETTI and the cobol keywords were in italian
GE 115 GE 415
ITEL AS/4 AS/5
CDC 6600
and the IBM list
7090 7094
360/25 /30 /40 /50
370/115 /125 /138 /148 /158 /3031 /3033
4381 4391
3081 3090/200 3090/400
S/7
9021 1 model
9121 2 of hem
9221 1
9672/ a few of them - at least 4 models |

Just an amendment statement to PeD's experiences with all those iron pieces, and also to top them ! :-)
In the late 19sixties in Cologne, Germany, i had a frantic, light animally amusement with a sex addict blond female operator on a IBM360.
A greatl experiences !!! Just something you never forget.
360/370, 4331/4341, S/370, S3/90, i saw them come and gone.
But never had such fantastic moments again.
@PeD >>...champ bottle in a mainframe ???
Were used to store our bottles of red wine in the false floor to keep them in the right moderate temperature.
Regards, UmeySan |
