They wrote ALL the interface code from scratch while they were designing the interface. We stopped publishing the CAS. In the 4341 the channel microcode was "registered IBM confidential" and my copy couldn't leave the office unless I logged it out. I suppose you could try to decompile the diskette but, as far as I know, nobody ever did. In real life the technology cycle was going so fast any clone someone made would be obsolete before it made it to the field. 370 channel pretty much gave way to ESCON anyway. They did not have to reverse engineer, as there was a void before they did it. Amdahl never made profit because after the 470 v6 about the time Amdahl got a clone out, IBM dropped the price on their unit. IBM had already covered their design costs, while Amdahl had to try to recover theirs with a greatly reduced price. But IBM may have used other peoples code in some of thier projects. ATM's were first developed by NCR, and you have to bet IBM looked at them very closely when designing theirs. |

Unfortunately not or we woulfd have had a better feed module ;-) Unfortunatekly the 3624 and 3614 were built with as many IBM off the shelf parts as they could. NCR had a lot better ATM and it took IBM 15 years to build as good a cash register. By then they were repackaged PCs anyway. IBM had better salesmen also. Macy's San Francisco was looking at new POS (Point of sale) system and the NCR terminals were better and smaller wire to run. The NCR sales guy told Macy's that they would have to run the terminal wires in conduit past all the florescent lights, and the IBM sale guy said not needed with the IBM terminals. They needed the conduit also, but the IBM guy knew the fire department required the conduit. So Macy went IBM. |

I carried a 453 for about 20 years and I still have it, a parting gift when I retired. I have the portable 200 mhz Tek. ones designed for portability. Forget the number, as I loaned to a buddy a couple years ago and he asks me every once in awhile if I need it back. Got it at another company I did the sustaining engineering for. The vertical circuit was not working, and the unit had been written down. They gave it to me, and the Field service lady sent it into Tek for repair. So I got a nice scope. Rarely have need for it. |

I think IBM and Tek developed it jointly I know they are hard to break. I also got out of there with a Tek 465 and a Dranitz 656. I had a PT3 but I gave it away but I still have my 210 dataprobe TP line monitor. When IBM folded up the service business in the late 90s they chucked millions of dollars in test equipment. Now everything is just "cut open the box and plug in a new one". Nobody fixes anything. I saw the writing on the wall in the 80s and started filling my wallet with cards. IBM got me BICSI certified, I am a Fl licensed electrical inspector, I got HVAC trained in Installation Planning school and I got some LAN certifications, unfortunately mostly Token Ring and IBM software oriented. I also got pretty good with DB2 and the IBM version of SQL. With all that I was still out of any meaningful work in 96 so I took the deal. My only interest in computers these days is building and maintaining my own PCs. High school friend was an IBM regional specialist at the end. He also saw the writing on the wall and took the buy out. Fortunately for him, he and I owned a construction equipment leasing operation on the side and after I moved for work he took controlling interest and with a minority partner was able to pay for his boys college education. |

They needed the conduit also, but the IBM guy knew the fire department required the conduit. So Macy went IBM. It was a myth that flourecent lights affected the baseband LAN IBM used on the 46xx registers and the S loop on the 36xx registers was tougher than that. I did a lot of tests in the lab on both. The S loop ran so slow you couldn't break it. We wired with STP and it would run on doorbell wire. The baseband LAN run with CAT3 was immune to anything a ballast could throw at it. It only ran at 1mz. We ran UTP all over shopping malls and fast food joints here without much regard to anything. (no conduit, just "plenum rated cable") They worked fine. Later when I acually got certified as an electrical inspector I know most of that wiring was not legal. I think the IBM salesman must have known that the San Francisco regulations required conduit. So he had the best of all worlds. A good LAN and the ability to say no conduit required even if it was. He was just a better prepared peddler. |

That almost sounds like a Chicago thing. In Florida (and Md) you can run low voltage cable in a plenum Tbar ceiling if it is plenum rated. You just need to support it above the ceiling tile. That is a National Electric Code requirement. Usually it just got thrown up there tho. The Independent Republic of San Francisco. |

Usually it just got thrown up there tho. The Independent Republic of San Francisco. Let me guess, has to be installed by a union electrician too? It was so bad in Chicago that CEs couldn't run interface cables under the floor in the computer room. I was in the education center and I pulled a floor tile to move a machine over a square and the management had a cow right there. They said if anyone saw me there would be pickets in front of the building or something. They were all in a chase anyway. They also require EMT for all residential wiring there, no Romex. SF is a huge union town. But we could at least run our own cables. Worst computer disaster I witnessed was moving a system from one room to another. The original room had a missed wired plug for 110V 30 amp for a card read punch. The original FE had rewired the plug on the reader to conform to the bad plug without telling anybody or leaving a note. Moving the system to the other room, I checked the receptacles as to normal operations and found it correct. Left 110v on the frame of the reader. Luckily was far enough from the wall and any grounds to keep from killing anybody. Worked fine offline and after we turned off all the power and hooked up all the logic cables to the CPU and reader and when we turned on the power to both units, CPU 208 3 phase 208V. It looked like a scene from Voyage to the Bottom of the Sea. Sparks and flaming parts of PC boards flying out the open doors of the CPU and card reader. About $150k damage in 5 seconds. CPU never ran again. NCR ate the cost. Another install the Electrician (union) ate the cost. HE swapped one of the hot leads and neutral in one of the junction boxes before it got to the CPU receptacle. |

Another install ... the Electrician (union) ate the
cost. If any. HE swapped one of the hot leads and neutral in one of the junction boxes before it got to the Card Punch receptacle. My man pluged it in, and fire and copper squirted out of the socket. He went to sick bay for bandages, and underwear. After that I metered ALL new relocation, and wireing. The union guys at McDonald Douglass LB got to know me, and backed off after me telling them what happened. Oh, something "boat" http://www.densnet.com Den |

IBM never had any 110v equipment in the computer room. We didn't even bring a neutral to the distribution panels. Even the smallest stuff was 240 or 208v. Later they did start putting in 120v plugs for terminals but a lot of places just plugged them into the convenience outlets in the frames. (transformer fed) We had lots of 120V stuff. |
