Re: Anything we should steal ? - Definitely
The much under appreciated IBM TSS/360 operating system also had memory-mapped files, decades before the FS-inspired System/38 (iSeries these days). Basic problem with TSS was that it was well before its time, and the S/360 model 67 hardware was never adequate to run it. While it was possible to get a 32-bit addressing version of the model 67, no S/370 models offered it, so customers such as General Motors who had built their early automobile CAD system on TSS were unable to migrate TSS to S/370 and had to rewrite/restructure their CAD software to run on the 24-bit virtual of S/370, and also lost the ability to have memory-mapped files.
