>>Hi, Bill.

>>My five cents...

>>I'm not sure what the logic was in selecting machine numbers back 
>>in the 1960s.  There did see to be some order to it however.  I 
>>believe that they were all assigned by the product marketing folks 
>>in White Plains.  Development had their own names for unannounced 
>>machines like NS, FS, Shark, etc.  (This was good because some of 
>>them never saw the light of day.)
>>
>>I seem to remember hearing that the 70xy machines were the 
>>"high-powered" machines.  Those numbered with the odd numbers (701, 
>>7030, 7070, 7090) representing the more scientific (academic) 
>>marketplace and the even numbers were perhaps more business related 
>>(7040, 7080).  The last digit changed when there were improvements 
>>with the same processor -- 7044, 7072, 7094, etc.  (This falls 
>>apart slightly when I remember the bank I worked for planned to 
>>install a 7070 to do commercial banking applications.)
>>
>>Machine numbers beginning with a 1 were priced lower and had much 
>>smaller processing power.  Included here were the 
>>1401/1440/1460/1240 and 1620/1710.  In the mid 1060s, the 1800 and 
>>1130 were introduced using some of System/360 technology.  The 1130 
>>was to address the 1620 marketplace and the 1800 the 1710.  (There 
>>were a lot of communications devices in the 10xx number range too 
>>-- 1050, 1060 families come to mind.)
>>
>>System/360 came along and most of its machine numbers were in the 
>>2000 range.  Processors began with 20xx, disk with 23xx, tape with 
>>24xx, card I/O with 25xx, remote I/O with 27xx, control units with 
>>28xx.  (29xx was reserved for RPQ devices which became a bit more 
>>main line.)  System/370 used the 3000 range of numbers.
>>
>>Things went a bit wild in the late 1970s when the 8100 and 4300 
>>were announced.  There are a lot in the 9000 range today -- which 
>>had been reserved for RPQ devices.
>>
>>I believe that there is a problem today with some machine numbers 
>>being recycled -- as some of the "printer company" devices show.
>>
>>But to answer your question why "1130" was chosen, I have no idea 
>>why that set of numbers was selected.  Hopefully, someone else may 
>>have better insight.
