Here is a thread about Year 2000 IBM 370/390/ESA and future z emulators. FSI had been selling 390/ESA emulators through IBM, but would not get a license to emulate z processors. https://tech-insider.org/mainframes/research/2001/0308.html
PSI was trying to sell Itaniums running an emulator to run IBM Z operating systems. Lawsuits were filed and settled by IBM buying PSI. https://www.theregister.co.uk/2008/07/02/ibm_buys_psi/ Then Neon was selling zPrime to run DB2 on zAAPs, lost the lawsuit by the judge ruling IBM's contract controlled what could run on zAAPs, and was bought out by IBM. https://www.theregister.co.uk/2011/06/01/ibm_prevails_over_neon_zprime/ Then Turbo Hercules was set up to sell x86 rack mounted servers with an high speed assembler to run z systems for Test and Disaster Recovery. They shut down when the court ruled the contract covered what processors could run what software (Neon zPrime) and the EU dropped their investigation about tying IBM Z software to IBM z processors. https://en.wikipedia.org/wiki/Hercules_(emulator)#TurboHercules On Fri, Apr 10, 2020 at 12:28 AM Grant Taylor <0000023065957af1-dmarc-requ...@listserv.ua.edu> wrote: > > On 4/9/20 5:23 PM, Bob Bridges wrote: > > This is new to me.
