I don't remember whether it was one of the docents at Haus zur
Geschichte der IBM Datenverarbeitung at Sindelfingen, or at the
Computer History Museum at Mountain View, who told me that IBM was
developing a machine to be designated 1480, as part of the 1401-1440-
1460-1410 series, with newer technology, roughly contemporaneously with
the 360. When IBM decided to put all its eggs in the 360 basket, The
1480 team somehow survived and produced either the 360/20 or 360/25. An
8k machine would be a bit weird in this series, since 1410 was already
100k. Does anybody know more details about this?
Samir Husson wrote a book about the 360/30 that described the
microcode. Has anybody built a 360/30 from FPGA? Does anybody have the
360 and 1401 microcode for it? How about the Compatibility
Initialization Deck to run the 1401 microcode emulation?

What model of a 360? 8K sounds a lot like a Model 20, which the
purists
may not consider to be a "real" member of the family. I had not realized the IBM 360 was 60 yrs. old
this month. I
worked on
such
a computer in the late 60s in Toronto. What one could do with 8
Kbytes of
ram was remarkable!
Happy computing

Real time sharing, not a 16K PDP 8?
